Eric, back in the day (early 70's) we used to remove the U-Joints in a vice with the sockets as you did, which works fine, and no damage to the drive shaft. We didn't have the tool back then. I've watched about 8 other videos on how to replace &-Joints and all of them took two sockets and beat the heck out of them with a BFH, and that sent chills down my spine watching this, I mean really banging very hard with the hammer. Great to see a real caring mechanic doing things the correct way.
replaced my first ever uni joints today! for the ordinary dude who needs a vice and doesn't have one, buy a vice. for the ordinary dude without a vice but has uni join cups painted and rusted in - buy the tool and use an impact. with the paint and rust I'd say I spent about 97% of the time removing the old rusted cups and sanding the drive shaft and flanges clean, filing out burrs etc. installation was so easy by comparison, probably 10 mins a piece (I had 3 unis in a 2 piece shaft to give one an idea. I needed a vice, and this was the perfect excuse to buy one. if I had my time again I'd probably buy both. But I did it the hard way and I learned a great deal. thanks Eric! I watched a few vids and this was by far the best
Forgot how relatively simple this was, but most importantly all the little tidbits and reminders are what I appreciate the most. Top shelf instruction there brother! Thanks! Stay dirty!
Thank you. I broke a yoke on a rototiller. Replacing the yoke was fairly easy, but I had no idea how to install the U joint. Your farm style method (no special tool) worked great. Again, thank you.
Had my auto shop teacher show me a method to loosen those outside clips up real fast. Take that socket the fits just inside the hole of the yoke and place it right up against the clip. Now rap it with a hammer a couple of times. Breaks those clips loose every time. Another method you can use to push the cups out is take the sockets and use a large C-clamp to press them. Just in case you can't afford to buy the tool and don't have a vice. I've also used the hammer method as well. Sometimes you just do what you have to to get it done.
Have done 1350 series joints several times. Used to use a 6 inch bench vise and did it with a USA made 6 inch c clamp once. Both removal and installation. Bent that c clamp removing. No faith in the Chinese c clamps around now. 2 days ago I was struggling with a vise and 3 foot pipe extension on the handle. Didn't want to move. For the first time I tried the hammer method. So much easier! 2 lb hammer and 24 oz ball peen was all I used. 5 inch diameter carbon fiber covered aluminum driveshaft on a 1992 GMC C2500. C-clamp to install would probably work well. I repeat, had no trouble at all removing these u-joints with a hammer. Do your best to keep things squared up. Don't use heat on aluminum, they sometimes warp. No need for penetrating oil. Study a few videos, read some posts and grab your hammer! Otherwise take the driveshaft assembly in to a shop that does this work everyday.
If you have some experience, that is actually the fastest method. I've installed hundreds of u-joints with a hammer and workbench, but unfortunately my boss wouldn't approve of the beer
How timely. I just ordered a set of u-joints from RockAuto for my 2000 Expedition. I have some non-specific vibration that I can't track down. When driving slowly next to a reflective surface I heard a rotational creaking coming from under the car. It's videos like yours that give DIYers the confidence to be DIYers. Thanks Eric.
I really appreciate the video walk through, I consider myself "Mechanically inclined" but I've always been intimidated by U-Joints and this video gave me the confidence to do it myself this evening. Thanks!
I would also add that if you are doing this and not swapping the yoke, mark the relationship of the shaft and the yoke so that you put it back on in the same location and don't risk getting them out of phase/balance. Also if you ARE swapping yokes for some reason, make sure they will work. Bearing caps/cups come in many different sizes with very low (.001") tolerances. Make sure the yoke you are using is the appropriate size.
sobeforlife when you are swapping the rear u joints are the front and back of the rear different or do you get 2 of the same u joints? And if you already took everything apart and didn't mark where it was at how do you know where it goes?
I have to thank you for this video Ericthecarguy. I've been wrenching professionally 13--14 years, I'm master certified but U-joints are the one task that always give me trouble. Watched this a few days ago and used some of the tips and tricks today on a 2 piece drive shaft on a Tacoma.
I just called a local auto parts store to see if they offer services like pressing u-joints. But I forgot that auto parts stores are worthless these days and only want to sell you parts that don't fit. So then I remembered to check ETCG and was pleased to see the use of a bench vise, because I have one. You couldn't imagine my disappointment when I discovered my vise was about 1/2 inch too short fully open.
Those are great tips that will come in handy for many people, since U joint replacement is such a common thing. You had better luck with the snap rings than I did---on the rusty northern cars I worked on, I had to chisel mine out.
Lots of great advice in this video, such as making sure the clips are seated properly, tapping on the joint at the end, and direction of zerk fitting. Eric has great little tips that would be easy to skip over but are still important.
Eric, I've enjoyed your vids for a long while now. Full disclosure: I'm not a technician nor will I ever DIYer. I'm just a fan watching a "BOY WITH TOYS". I had a random thought watching this one today: You must own stock in and/or have cases and cases of "penetrating oil" somewhere hiding in the shop. It seems that use it "by the gallon"! Looking forward to Friday's installment. . .Keep on Keeping on!
I did mine today with the 20 ton Harbor Freight press I bought last month to do the rear wheel bearings on my 03 Mountaineer. One thing I haven't seen covered in any videos is the old snap rings breaking. Lots of fun when that happens. Six out of 8 of mine broke like that. Easiest solution I found was to get one side out entirely, then just press from the other side. Once the cup is out, it's much easier to dig out the broken ring. I had expected it to be a frustrating balancing act trying to use the press and keep the sockets lined up with the yoke, but it really wasn't that bad. The first one went that way because I was trying to keep a 30mm socket aligned on the bottom, and a 17mm socket on the top. The last three I did by just pressing the u joint from one side until it bottomed out, then I flipped it over and put the 17mm socket in the yoke hole and the 30mm socket on top so I could press the cup all the way through. Wasn't that bad at all, and my horrible clicking and grinding noises are gone. On top of that, it no longer feels like the brakes are on when I let off the gas. One was completely seized in one direction. I'm guessing I should have done this a long time ago.
Wow that looked so easy. My 2001 F150 had the axle side u joint snap at about 210k miles. It felt like the whole rear end fell out. I checked it, figured I could drive home. About a mile later the driveshaft shot out. So I put it in the bed, turned on the 4x4 which just made it front wheel drive at that point, and drove home. When the u joint initially broke it twisted the shackle. So I broke a clamp trying to press it. I hammered for an hour. Eventually I got a diablo demon steel cutting reciprocating blade and spent two hours and two blades cutting out the u joint. I wish I could have pressed it out like you. Geez.
Push the cross piece back and forth after each yoke install to push the cups apart and out against the clips. Gives the cross that little bit of clearance it was designed with. Once installed, grease them ON THE BENCH. you can use the vise to put pressure on the cross and push it against the cups....this allows you to get 100% new grease flowing out of EACH of the 4 cups all around each one's lip seal. Don't stop until you have replaced all the grease that came in it. If a cup doesn't flow grease, put pressure on two of the other three as much as possible and 'hammer' your grease gun with palm of hand or helper to 'pulse' grease into that last stubborn cup. I've wasted lots of grease trying to get new grease into every cup, but never replaced a joint more than once. When it's on the car, you can do the same thing; hang on the drive shaft with lots of your body weight to bury the cross into two of the cups and 'aggressively' grease the joint...keep after it until you see new clean grease come out of every cup. The last resort to clean a dirty, not flowing cup: carefully remove the rubber seal (slide onto cross without tearing it). move cross away as much as possible from the bad cup and grease. Then, spin shaft around so you can hit it with rubber mallet and force cross rapidly into bad cup....hammering action will force the dirty clogging grease out.
Your video helped me a lot, although I had one complication... my U-joints were so corroded that I had to use A LOT of pressure on the ball/U-joint removal tool - so much that it actually started to bend the yoke before it popped free. Re-installation meant using way more pressure than I probably should have to get the snap rings to seat. Rust belt truck that sat in the grass for 2 years, so it was probably worse than most. Now we'll find out how many miles the new joints last since I had to squeeze the tar out of them...
Thanks for this video. You're probably the only video that shows a sealed u joint install. Everyone else shows how to do it with a zerk fitting. My concern was that I wasn't sure if you needed to add any grease on the sealed u joints. Ordered the parts, will be doing this job on Saturday along with replacing the rear transfer case seal.
Yeah I did it with a hammer at a guardrail on the interstate. I knew it was bad, bought a few buy just was surprised to see my drive shaft fall off. So replaced it right there!! Good video!!
Eric, at 8:00 did you step over a 'careful' rule by placing the aluminum drive shaft in a vice? There are too many amateur DIY mechanics do not know the damaging force of a vice and will toast their alum shaft with super vice handle torquing. Good vid, Thanks. 122618.
I have alway put some extra high pressure grease into each cap when I remove them from the trunnion,that way if you accidently drop a cap or bang it around while installing it the grease will keep the needle bearings in place. just don't install the zerk fitting until the joint is fully assembled in the drive shaft. I have replaced u joints in the middle of nowhere using nothing but a hammer,flat screwdriver, socket and a solid surface to support the drive shaft as you tap the joint out, but that is a last resort.
Makes it so much easier when you drop a cap and the needle bearings go flying. You drop one of those suckers from a bench vice you mind as well start heading back to the parts store
Driveshaft or axle. Musta been a late night. Here I thought it was going to be ball joint press vs hydraulic press when I clicked on this. Oh well, good tip on grease fitting alignment towards driveshaft. Thanks Eric.
Hey Eric, maybe it's already been said somewhere along here, but I had a minor cringe moment when you were holding the aluminium driveshaft in the vice. I would kindly suggest using a couple of lengths of aluminium bracket cut to the length of the vice jaws and placed (or fixed) into the vice to make a set of "soft jaws" for the vice when working on softer metals. No doubt you are aware of the practice, and you made a point of telling us not to clamp down hard on an aluminium driveshaft, but I think it may be worth passing along such a simple technique. It has helped me to prevent marking up some old, expensive and hard to replace soft metal bits on some of my old motorcycles. Thanks for another great video, and stay dirty!
I've been told it's a good idea to put the zirk fitting so it is in compression. The fitting should be in the leading end of the driving yoke and trailing end of the driven yoke.
Some U joints that are lubed for life do require extra lubrication. Moog super strength ones come to mind. Mine were like the one Eric installed but the moog FAQ menntioned non-serviceable ones requiring extra grease. They say that for both styles what comes in the joint is just for shipping (assembly lube if you will) and that the caps need packed with grease before one begins.
A vice is not a press, I've seen vice Jaws explode from that type of use. Also, if the cup is stuck, you can bend the ear and screw up your driveshaft. You elude to that when you say you're afraid of screwing it up.
I did the u-joints recently in my 1999 S10 Blazer ZR2, there was surprisingly an original u-joint that I had to melt the plastic retainer out of. Pretty interesting, but also easy to remove. Just heat and wait for it to ooze out, and it comes out pretty fast! We used the sockets and vice method.
What about the hammer and vice method that every PTO shaft manual recommends? Place the cross in the vice open enough to only stop the cross and strive the opposing yoke below the cap and repeat in opposite orientation?
Good techniques. However, since you have a hydraulic press, why didn't you use it instead of the vise. Additionally, most vise manufacturers advise against opening a vise to the extent you did because it can break the vise (it is a casting not a forging (just saying, even though I do it myself)).
Eric I have used a air hammer and a Yard store in wichita ks or aircraft spruce in tulsa ok. I also use the tool to remove tie rod end tapers and ball joints much easier on me than 2 4 lb hammers.
Usually, that means that dirt got in when you replaced them, or somehow the grease got contaminated or washed out, or wasn't good enough in the first place. And they need replacement again.
Hey Eric.. do you think a 6 inch vice is large enough for working on ujoints? I have a 1st gen Colorado. I ask bc i need to do mine and I don't really have a space to do it. So I saw they saw a vice that you can attach to your trailer hitch. I thought that would be a good idea but I only see one for 6 inches.
Great job I have one question I have a 94 Ranger splash supercab 3.0 125 " wb It has two drive shafts with a carrier bearing Now the u joint behind the carrier kind of comes apart with 4 bolts I think 9mm bolts that holds the u joint what is that called, And is there possible to put one drive shaft in this truck
I was watching closely how you removed the old and installed the new U-Joints and will put that knowledge to use if I have to replace on on my vehicles.
Any recommends when the bearings are pressed in like in my newer mercedes? They say i need to buy a whole new shaft :( there isnt a snap ring, only the edge is kind of hamered in. Any advice?
What's your take on applying a bit of anti-seize to the outside of the caps and in the gap where the snap ring sits upon reinstallation on 4X's that are used in adverse conditions, i.e., water n mud on a regular basis? I've been doing this for 30-odd years with no ill effects and it really helps when you need to service the joints.
Is it advised to make sure you mark each end of the drive shaft in relation to the rear end and tail shaft of the transmission to make sure it goes on the same way it came off?
So what driveshaft is that exactly? I'm building an '81 Granada with the same wheel base, axle and trans combo. I heard you mention a explorer driveshaft just would like more details.
Eric can u tell me what that first shaft you worked on is out of? in other words what vehical is that yolk for? thanks for the help I have the same one I'm changing it out for one from a th350 but would like to know where it came from as its from a junkyard
Good tip on hitting the ears to settle the caps. I wish I knew that when I did my joints... that was a struggle. Ended up killing a needle and having to buy another $20 joint (I wasn't using the cheap kind).
Hi Eric, I really need your help. I have 1998 toyota 4runner 4 cyclinder manual. After I replace the drive shaft and the drum brake. It's start have a death wobble(it's come and go at the highway speed) I bought it to several mechanic(even a suspension specialist) but they can't figure out the problem is. When it's has a death wobble the brake wont engage properly(I need to pull over to complete stop to stop the death wobble before I can drive again)
i know you have a couple videos on idle control and fixing idle problems. but i good one i need help with. 97 del sol. wont idle at all. anything? will start, will drive, everything else good, but wont idle.
if you have a cheap vice i would refrain from using the vice from being the only tool. did it with my old harbor freight vise. a great way to make it easier on yourself and the vise is set it up with the sockets get it good and snug with just your hand, no pipe, and give either the vice or the shaft a good few whacks with the hammer just until you feel the resistance let go, and repeat.
Hey Eric ! On Honda CRV's '02 I changed it on mine a few times by a driveshaft transmission shop They weld the jointe to the yok Was wondering if it's a normal thing to do Now if i want to change the jont i need to take out the welds
I was shaking my head when you busted out that powertool, thinking: "Bet he's going to say don't use powertools." And then you damaged your part :-) Stay dirty and keep up the good work.
yeah they have 20ish needle bearings they are long with small diameters, older Mopars used to lose the caps and bearing retainers fairly often, and when they did sounds and feels like the car is being ripped to pieces.
Needle bearing. It's the bane of anyone's existence when they come apart. The cross is actually made out of 4 + 1 major components (non counting the needle rollers) 4 cups (with needle rollers inside) and 1 cross. The cups, are what get positively retained inside the U joints and the cross "floats" on those needle rollers. And yes, water, dirt, crap, wear and tear damage these in time, and you get that distinct noise, repeating and annoying (tho, with varying degrees of amplitude based on how bad the U join assembly is screwed up, oh, and i guess how large the needle rollers are, some cars have them quite big, when those fail they make a lot of noise). All that being said, this area is not my cup of tea, so, if you're really interested Google, wiki has a good article on it. The most interaction i've had with these was an old Merc that had been rusted in place at the joints. That was a PITA to change especially since they almost fused in place.
Also, as others have pointed out they do wear out. Sometimes causing noise. Look for orange dust around the bearing cups. I you see that, replace them.
I would like to know what that new elec impact you,re using. Looks like you got an upgrade or at least the batt looks different. I not gonna lie, I have missed a few vids, or at least havent been keeping up. Do you have a review?
Awsome video y'all thank you.. went to do mine and I think they gave me the wrong one for my 1988 Chevy 1500 cuz I went to tighten it all the way down once it was installed to my rear end.. and it was still loose.. I feel it should tighten down.. well it fell out going down the road.. I wonder if the auto parts store gave me the wrong one or what..
i use the vise method at home and the press at work. ive had some u joints so stuck and rotted in a driveshaft i first had to cut them out with a cut off wheel then press the caps out individually
Great tutorial. I've rebuilt a few driveshafts using a hybrid of these approaches, with a large normal C-clamp and sockets. It's fiddly getting the sockets to stay in place, but it's very doable. I'd add that in my experience not all zerk fittings are angled in one direction. Also some have circlips that you need a special pliers to remove/install.
Would recommend a wire wheel to clean up the yoke/driveshaft bores instead of a scotch brite spindle disc or sand paper. If an older vehicle had u-joints done previously, and the bores were recleaned with abrasives while replacing them again, they would probably be larger than specification, and could lead to the loose fitting bearing cups seen in this video. These style of cups are interference fit in order to prevent premature damage during driving, loose cups can lead to a plethora of problems down the road.
I asked this question over a year ago and didn't get a reply. I've heard under race applications you should install the grease zerk so it's under compression. Any truth to this?
Have you ever tried home made penetrating fluid the 50 ATF and 50 acetone? I didn't have a chance to try it but heard its a lot better then other penetrating fluids. what do you think?
What's up Eric. I've got a situation I've gotten myself into. I needed my u-joints changed, so I got my drivetrain off completely fine but when taking out and putting in the u-joints I had a lot of trouble. I think I may have pressed a joint through while it wasn't seated properly and removed some material from the inside of the yoke. I got the new ones installed, went for a drive and heard lots of popping. I checked, and sure enough my joints were now hanging out of the yoke and probably drive train too. The dealership was asking for $655 just to swap out the joints. I'm worried I've made a much more costly mistake. I think I can take off the drivetrain and bring it to a shop to get looked at. Any other options or advice would you have for a guy in my position? Thank you very much.
@@dericross341 Thank you for this reply. I do one every once in a while. I always wondered how a professional does them. Press or hammer. Now I know. Thanks again 👍

Method 3: beating the shit out of u-joints with shitty sockets, a sledge, and lots of beer.
If you have some experience, that is actually the fastest method. I've installed hundreds of u-joints with a hammer and workbench, but unfortunately my boss wouldn't approve of the beer
Brian X Method 4: log splitter
Brian X same and i cant get the last one in

Great video. Been years since i changed a UJ, under supervision. Your video brought it all home. Thanks from Mike in OZ.
what's crazy is you guys respond to video as simple like this. They are u joints please.eric is simply straightforward showing novice attempts
Those are great tips that will come in handy for many people, since U joint replacement is such a common thing. You had better luck with the snap rings than I did---on the rusty northern cars I worked on, I had to chisel mine out.

My concern was that I wasn't sure if you needed to add any grease on the sealed u joints. Ordered the parts, will be doing this job on Saturday along with replacing the rear transfer case seal.
Been a while since I've had to do this - this was a great refresher. Thanks!
Yeah I did it with a hammer at a guardrail on the interstate. I knew it was bad, bought a few buy just was surprised to see my drive shaft fall off. So replaced it right there!! Good video!!
Eric, at 8:00 did you step over a 'careful' rule by placing the aluminum drive shaft in a vice? There are too many amateur DIY mechanics do not know the damaging force of a vice and will toast their alum shaft with super vice handle torquing. Good vid, Thanks. 122618.
A large C-clamp and 2 sockets will work in a pinch as well. Done that in a parking lot in an emergency situation.
installing the new yoke didn't the cups go in to easy
without any pressure
is that going to be a problem ?
I have alway put some extra high pressure grease into each cap when I remove them from the trunnion,that way if you accidently drop a cap or bang it around while installing it the grease will keep the needle bearings in place. just don't install the zerk fitting until the joint is fully assembled in the drive shaft.
I have replaced u joints in the middle of nowhere using nothing but a hammer,flat screwdriver, socket and a solid surface to support the drive shaft as you tap the joint out, but that is a last resort.
what about the hammer, deepwell socket and block of wood while on your knees method?
Makes it so much easier when you drop a cap and the needle bearings go flying. You drop one of those suckers from a bench vice you mind as well start heading back to the parts store
Worked for me for years when I was broke.
I used a rock instead of a hammer.
@ paul: hahahahahhahahhaha!!! :)
Don't you just love Wilton vises? They're great tools. Nice video Eric, easy to follow steps with common tools.
Driveshaft or axle.
Musta been a late night.
Here I thought it was going to be ball joint press vs hydraulic press when I clicked on this.
Oh well, good tip on grease fitting alignment towards driveshaft.
Thanks Eric.
When I was a poor servant of Uncle Sam I used sockets and a hammer. You do what you have to do to get by.
Abunai One the poor servant part is true-I feel ya
You have a good camera man! Excellent explanations too. Thank you.
Excellent video! It’s also applicable to pto driveshafts on farm implements such as old snowblowers, which I’m working on right now.
Hey Eric, maybe it's already been said somewhere along here, but I had a minor cringe moment when you were holding the aluminium driveshaft in the vice. I would kindly suggest using a couple of lengths of aluminium bracket cut to the length of the vice jaws and placed (or fixed) into the vice to make a set of "soft jaws" for the vice when working on softer metals. No doubt you are aware of the practice, and you made a point of telling us not to clamp down hard on an aluminium driveshaft, but I think it may be worth passing along such a simple technique. It has helped me to prevent marking up some old, expensive and hard to replace soft metal bits on some of my old motorcycles. Thanks for another great video, and stay dirty!
Great video! It helped a lot to let me know what I'm in for in replacing the u-joints on my '95 van.
I've been told it's a good idea to put the zirk fitting so it is in compression. The fitting should be in the leading end of the driving yoke and trailing end of the driven yoke.
I've seen them shear when mounted in tension.

Excellent. Thanks for taking the time to show both methods.
When the cross goes bad. Does it sound like your brakes are worn out? As in kinda the same noise?
Some U joints that are lubed for life do require extra lubrication. Moog super strength ones come to mind. Mine were like the one Eric installed but the moog FAQ menntioned non-serviceable ones requiring extra grease. They say that for both styles what comes in the joint is just for shipping (assembly lube if you will) and that the caps need packed with grease before one begins.
videos don't get any better - well done
A vice is not a press, I've seen vice Jaws explode from that type of use. Also, if the cup is stuck, you can bend the ear and screw up your driveshaft. You elude to that when you say you're afraid of screwing it up.
That was the best instructional on u joints I've seen, thanks
Nice video. Glad to see some of the issues and how to deal with them. Thanks!
Exactly the info I was looking for. Excellent teacher. Thanks much!
lol..."yay, I'm a u-joint yay!" Eric do voice overs on cartoons. great informative videos as always!
Just had the U-joints changed out on my van. Damn Eric you were a week late with this video. Oh well next time I will know how to do it myself. -John
I did the u-joints recently in my 1999 S10 Blazer ZR2, there was surprisingly an original u-joint that I had to melt the plastic retainer out of. Pretty interesting, but also easy to remove. Just heat and wait for it to ooze out, and it comes out pretty fast! We used the sockets and vice method.
I've done these two methods and my favorite is using a hydraulic press. Freaking magical compared to the bench vise and the u-joint tool.
What about the hammer and vice method that every PTO shaft manual recommends? Place the cross in the vice open enough to only stop the cross and strive the opposing yoke below the cap and repeat in opposite orientation?
The Vise method is really useful! Much better than using a hammer. Excellent video, well filmed and explained.
Eric, any advice on correct replacement size on U Joints? I've got a 73 F100 but can't find a replacement guide.
Good techniques. However, since you have a hydraulic press, why didn't you use it instead of the vise. Additionally, most vise manufacturers advise against opening a vise to the extent you did because it can break the vise (it is a casting not a forging (just saying, even though I do it myself)).
So glad I found this video. I have the inside clips. was having a little trouble getting the new cap in far enough to get the snap ring on.
Eric your opinion on greasable vs sealed U-joints; worth the strength loss? Vehicle does lots of water crossings and heavy mud.
Eric I have used a air hammer and a Yard store in wichita ks or aircraft spruce in tulsa ok. I also use the tool to remove tie rod end tapers and ball joints much easier on me than 2 4 lb hammers.
I will probably never do this but good to know how. Thanks Eric.
Vjjjikk,l ...
On the GM driveshaft, after you torch the wax/plastic tab to remove the old u joint what holds the new u joint in place if there is no clip?
What does it mean if once you replace the u joint and the vibration goes away, but three weeks later the vibration is starting to come back.
Usually, that means that dirt got in when you replaced them, or somehow the grease got contaminated or washed out, or wasn't good enough in the first place. And they need replacement again.
1:53 Be sure to use your 12 point sockets like Eric is doing. That's about all they're good for anyway.
Hey Eric.. do you think a 6 inch vice is large enough for working on ujoints? I have a 1st gen Colorado.
I ask bc i need to do mine and I don't really have a space to do it. So I saw they saw a vice that you can attach to your trailer hitch. I thought that would be a good idea but I only see one for 6 inches.
Great job I have one question I have a 94 Ranger splash supercab 3.0 125 " wb It has two drive shafts with a carrier bearing Now the u joint behind the carrier kind of comes apart with 4 bolts I think 9mm bolts that holds the u joint what is that called, And is there possible to put one drive shaft in this truck
I was watching closely how you removed the old and installed the new U-Joints and will put that knowledge to use if I have to replace on on my vehicles.
Any recommends when the bearings are pressed in like in my newer mercedes? They say i need to buy a whole new shaft :( there isnt a snap ring, only the edge is kind of hamered in. Any advice?
What's your take on applying a bit of anti-seize to the outside of the caps and in the gap where the snap ring sits upon reinstallation on 4X's that are used in adverse conditions, i.e., water n mud on a regular basis? I've been doing this for 30-odd years with no ill effects and it really helps when you need to service the joints.
Hi eric..paul from the UK..gonna change the universal joints on my transit motorhome..love the video..you make it look so easy...paul..
I like using anti-seize and will do so when I do mines. Will make thing move much easier.
GREAT VIDEO FOR THE CLASSICS.HOW OFTEN DO YOU GREASE THE ZIRCS? WHAT ARE THE TOP BRANDS ?
Is it advised to make sure you mark each end of the drive shaft in relation to the rear end and tail shaft of the transmission to make sure it goes on the same way it came off?
yes. drive shaft is balanced that way.
So what driveshaft is that exactly? I'm building an '81 Granada with the same wheel base, axle and trans combo. I heard you mention a explorer driveshaft just would like more details.
Eric can u tell me what that first shaft you worked on is out of? in other words what vehical is that yolk for? thanks for the help I have the same one I'm changing it out for one from a th350 but would like to know where it came from as its from a junkyard
Great video. What happens if you push one of the caps too far? Do you just push it back with the other side?
Good tip on hitting the ears to settle the caps. I wish I knew that when I did my joints... that was a struggle. Ended up killing a needle and having to buy another $20 joint (I wasn't using the cheap kind).
Hi Eric, I really need your help. I have 1998 toyota 4runner 4 cyclinder manual. After I replace the drive shaft and the drum brake. It's start have a death wobble(it's come and go at the highway speed) I bought it to several mechanic(even a suspension specialist) but they can't figure out the problem is. When it's has a death wobble the brake wont engage properly(I need to pull over to complete stop to stop the death wobble before I can drive again)
i know you have a couple videos on idle control and fixing idle problems. but i good one i need help with. 97 del sol. wont idle at all. anything? will start, will drive, everything else good, but wont idle.
Good catch, you forgot the 3rd way, and 4th way. Third way hammer and socket in vise grips, fourth is get a nice guy like u to do it. Great vid Eric
i wish the one i was working on right now was THIS rust free!!! indiana boy here and mine is rusty gold and stuck! lucky dog!
if you have a cheap vice i would refrain from using the vice from being the only tool. did it with my old harbor freight vise. a great way to make it easier on yourself and the vise is set it up with the sockets get it good and snug with just your hand, no pipe, and give either the vice or the shaft a good few whacks with the hammer just until you feel the resistance let go, and repeat.
Hey Eric !
On Honda CRV's '02
I changed it on mine a few times by a driveshaft transmission shop
They weld the jointe to the yok
Was wondering if it's a normal thing to do
Now if i want to change the jont i need to take out the welds
Seems to exist u joint replacement for crv without welding, is it possible ?

"MORE!!!"
great vid Eric.
About the way it generally goes....nice demo and explanation of the different type and methods.
What do you do if the yokes have been squeezed in and you can no longer get the clips in their grooves on both sides, but only one side?
What's your opinion on installing u-joints so the grease zerk is under compression?
Great, informative, video. Thanks !
Why does the grease fitting have to face towards the dry shaft? Is this because it is easy accessible to grease?
I was shaking my head when you busted out that powertool, thinking: "Bet he's going to say don't use powertools." And then you damaged your part :-)
Stay dirty and keep up the good work.
thinking the same thing....lol
The old "do as I day and not as I do."
Dumb quenstion, why would you change theese? Do they have some bearings that wear out or? ;)
yeah they have 20ish needle bearings they are long with small diameters, older Mopars used to lose the caps and bearing retainers fairly often, and when they did sounds and feels like the car is being ripped to pieces.
the grease inside get contaminated over time and the bearings rust and seize. they get noisy.
Needle bearing. It's the bane of anyone's existence when they come apart. The cross is actually made out of 4 + 1 major components (non counting the needle rollers) 4 cups (with needle rollers inside) and 1 cross. The cups, are what get positively retained inside the U joints and the cross "floats" on those needle rollers.
And yes, water, dirt, crap, wear and tear damage these in time, and you get that distinct noise, repeating and annoying (tho, with varying degrees of amplitude based on how bad the U join assembly is screwed up, oh, and i guess how large the needle rollers are, some cars have them quite big, when those fail they make a lot of noise).
All that being said, this area is not my cup of tea, so, if you're really interested Google, wiki has a good article on it. The most interaction i've had with these was an old Merc that had been rusted in place at the joints. That was a PITA to change especially since they almost fused in place.
I needed to swap the yolk from one driveshaft to another.
Also, as others have pointed out they do wear out. Sometimes causing noise. Look for orange dust around the bearing cups. I you see that, replace them.
I would like to know what that new elec impact you,re using. Looks like you got an upgrade or at least the batt looks different. I not gonna lie, I have missed a few vids, or at least havent been keeping up. Do you have a review?
Awsome video y'all thank you.. went to do mine and I think they gave me the wrong one for my 1988 Chevy 1500 cuz I went to tighten it all the way down once it was installed to my rear end.. and it was still loose.. I feel it should tighten down.. well it fell out going down the road.. I wonder if the auto parts store gave me the wrong one or what..
i use the vise method at home and the press at work. ive had some u joints so stuck and rotted in a driveshaft i first had to cut them out with a cut off wheel then press the caps out individually
Great tutorial. I've rebuilt a few driveshafts using a hybrid of these approaches, with a large normal C-clamp and sockets. It's fiddly getting the sockets to stay in place, but it's very doable.
I'd add that in my experience not all zerk fittings are angled in one direction. Also some have circlips that you need a special pliers to remove/install.
Would recommend a wire wheel to clean up the yoke/driveshaft bores instead of a scotch brite spindle disc or sand paper. If an older vehicle had u-joints done previously, and the bores were recleaned with abrasives while replacing them again, they would probably be larger than specification, and could lead to the loose fitting bearing cups seen in this video. These style of cups are interference fit in order to prevent premature damage during driving, loose cups can lead to a plethora of problems down the road.
I asked this question over a year ago and didn't get a reply. I've heard under race applications you should install the grease zerk so it's under compression. Any truth to this?
did your original ford explorer driveshaft not work for you? or is that the original one you had?
Have you ever tried home made penetrating fluid the 50 ATF and 50 acetone? I didn't have a chance to try it but heard its a lot better then other penetrating fluids. what do you think?
I have made a small batch and it works well.
What's up Eric. I've got a situation I've gotten myself into. I needed my u-joints changed, so I got my drivetrain off completely fine but when taking out and putting in the u-joints I had a lot of trouble. I think I may have pressed a joint through while it wasn't seated properly and removed some material from the inside of the yoke. I got the new ones installed, went for a drive and heard lots of popping. I checked, and sure enough my joints were now hanging out of the yoke and probably drive train too. The dealership was asking for $655 just to swap out the joints. I'm worried I've made a much more costly mistake. I think I can take off the drivetrain and bring it to a shop to get looked at. Any other options or advice would you have for a guy in my position? Thank you very much.
I've always removed em with a hammer was how I was thought and never had any issues
I build driveshafts at my job. Got thousands under my belt. I always use hammer. Knock em out in a fraction of time. We all have what works for us.
@@dericross341 Thank you for this reply. I do one every once in a while. I always wondered how a professional does them. Press or hammer. Now I know. Thanks again 👍
What are you using for a breaker bar on the vise? Is it part of floor press jack arm?
Thanks for the great vid.
Yeah, is part of the floor jack! :)
This is a great example of a u joint fix up
