I installed a Tru-Trac in my own Chevy pickup. I bought a complete installation kit that included new, larger bearings and a shim kit when I bought the Tru-Trac. The installation was seamless and easy. Took just under eight hours from driving the truck into my shop to driving it out. Several things I'll point out in this video that are not 100% always true: one, the Tru-Trac is not a Posi. Posi is short for Positrac, which is the trademark name for GM's clutch-type LSD. The Tru-Trac is a Torsen-type (worm gear) LSD. Two, it IS possible to install the Tru-Trac without the shim kit. My Tru-Trac retained its recommended backlash using the factory-installed shims, and the shim kit was not needed. That may not be the norm, but it's possible you won't need the extra shims. If you can abide having the vehicle up on jackstands while you obtain the shims, I would not buy the shim kit until you find that it is required. Before you remove the bearing caps, mark them so you can identify left cap, right cap, up or down. You'll need to reinstall them exactly as they came out. When you press the bearings on the Tru-Trac, triple-check to make SURE you don't press them on upside down!!!!! You'll hate yourself if that happens..... You can omit checking tooth engagement. Tooth engagement is determined by pinion location, and since you don't touch the pinion gear when you instal a Tru-Trac, tooth engagement will not change. You only need to check/adjust backlash. Otherwise, this video shows some things very clearly and was well-presented. I'd recommend watching this and every other Tru-Trac install video you can find. Each one will show different things and have different tips. Remember, "If I can do it, you can do it." That's from Eric O. of South Main Auto; the best mechanic west of the Atlantic.
I’ve been putting of installing an LSD for years cause I don’t have a press and nobody around me will press bearings on customer supplied parts, and I sure as hell didn’t want to pay $1000 for an install. The socket to drive in the bearing was genius and Im mad I didn’t think of it earlier. I could’ve done an LSD install so long ago!! Man you make it look easy! Thank you for this video.
I always thought changing a carrier would be a pain in the ass, but thanks to you I have the confidence to change it myself! Thanks for the awesome video!
+Ali Haidar Thanks Ali! Make sure that you research the process of setting the pattern on the gears. That part can possibly get frustrating if you're not expecting it. A lot of times, when just changing the gears, the pattern will come out fine without needing to shim the carrier, but when changing to a different carrier, it's common to need to shim it to get the correct mesh of the gears. Making a pair of setup bearings with the old ones helps to make adjustments much easier.Good luck!
Thank you sir, makes what I've always considered an intimidating job a lot easier to understand. You've given me the roadmap to do it myself instead of finding someone else to pay, as I've always done in the past. Great video tutorial.
@@larryjohnson3033 Never heat up hardened steel (like bearings or gears) over 400 Degrees F unless the manufacturer specifically states a higher temperature ... Set oven to 400F to be sure and then it won't matter how long (just leave them over an hour.)
Nice video!! Way to show the kids whats up. Nice skills!! “Give a man a fish, and you feed him for a day. Teach a man to fish, and you feed him for a lifetime.”
Great video! It is sad that the backlash setup got toasted. You can't really do this job right without it. Thanks for taking the time though. It was still fun to watch. 👍
Great video, I used tips from this to DIY my own broken G80 diff. I want to give a good tip I discovered while putting the bearing on. Using a punch did not work at all for me and I was afraid it was going to damage the bearing. If you rent the ball joint press from advance autoparts, there is a spacer in there that fits the bearing perfectly and has room for the differential snout to come through.
Great videos man! I've done all this to my '78 C10 11 sec drag truck back in the early '90s. It makes me happy to see people building trucks. Chevy made such a welcoming canvas for such projects with the '73-'87 body style. Keep up the amazing work!!!!!
Hey man great video! You really do know your stuff. Im only 16 and have a 78 shorty stepside and your videos have really helped me a lot, they sure do get me closer and closer to having my ride back on the road. Keep up the good work!
Awesome video.........not saying that I would try it not knowing much about rear ends but I really appreciate that you were very specific on what you did and doing a visual description as you were talking just made the video so much better......thank you my friend
Two items: Safety: Put some boots on (not flip-flops) when you're working around dirty heavy equipment that could make a mess of your feet if something heavy and dirty (like the carrier) fell on them. Torquing down the Ring-gear: After all of the bolts are torqued to spec, go over them a second time to ensure they're all still at spec (usually they won't be). Repeat this step until none of the bolts move at the torque spec.
Really good video! I like how you take time to explain precisely what has to be done, as opposed to explaining after the job was done. Keep 'em coming....subscribed.
Thank you sir for the video! I don't have a very useful way to hold my carrier still to torque it down. The plan is to get a 3.90 gearset, pull the pinion out, put the diff in, use the brakes to hold it still while I torque it down, then pull the diff back out and install the 3.90 pinion.
good video man. i watch a lot of your videos when im stuck in a project and need to solve it. always with good information. video quality and a project is broken down in nice easy to digest sections. thanks again. Semper Fi!
Damn, I remember watching this when I was 16 in highschool looking at those prices in horror. Now I got the whole setup and installed thanks to this video that I remembered about from years ago 😂
Had to check this out before work! Good job, very informative. I plan on pulling up videos on the LS swap and rear-end upgrade shown here when I'm ready to do so as we have the same year/model truck. Keep doing what you're doing. It's greatly appreciated
+afattori316 Thanks brotha! Just remember to study how to set the gear pattern with shims. The difference made on the pattern by pinion shim vs carrier shim. That's the hardest part.
My only 2 critiques are leaving the axles in the tubes will usually damage the oil seal because the axle is pressing against it causing it to deform, and 2nd if you're reusing your gears you need to check the backlash before removing the carrier so you can shim the new unit to the exact same lash. Other than those, great video.
good video helped me explain it to my friend without having to do it myself. Wish i would have looked it up before doing it myself and having to call my old man
I'm getting ready to put this same unit in my Silverado. Thanks for the vid and for the updated information. I have no doubt I'll be successful with the install.
Thanks brother, I'm looking at rebuilding the one on my 65 Chevy c10, i want higer gears for better gas mileage. And it sucks to already be in fourth gear before you hit 30 miles an hour. Not to worried about having posi, just would be nice to drive highway speeds, and not make other folks angry because I'm driving slow! The only thing I haven't gotten into much is rear end, finding the info to do it isn't very easy. Been at it already a few hours.
thank you for this video ive been looking into posi but ive been raised with family who took everything to a shop to do it so i was alway slightly timid of doing my own work but since ive started i can say my upgrade bills are a lot cheaper
+kevin o Also, check each direction separately. If you try to check both directions, you'll usually contaminate the previous direction pattern on the ring gear with the opposite rotation.
I'm wanting to regear and put a locker in my 93 suburban, and all though I have never did a gear swap, I like to do my own work..does take some special tools that cost more money, but I also have a jeep that I want to reheat, so maybe it wil be worth it..your skill level and confidence makes it look easy...oh, and my sister would like your video just based on the Glenn Danzig song playing..shes got two daughters but for some reason she loves a song with a man warning mothers to not let their children walk his way..ha ha...well, I'm not the most logical person either.
Well done sir! I wish I had found a great video like this to refer to when I put my Richmond posi in mine! Still rocking 3.08 gears here I'll find a set of 3.42 or 3.73 at some point keep it up man!
What kinda use do put to that posi rearend??? Talking about the gear ratios that u're talking. Im dealing with a 2011 chevy Colorado 2.9 project for dayly driven and street racing and some drifting on weekends Can u suggest a nice ratio or i leave the 4.10 that i have right now... thanx
+AGearHead4Life I didn't think you'd reply, thanks. I'm doing the same thing your doing thats how I found your video. I'm going from a Muncie 4 speed to a Tremec 6 speed and installing an Ectec locker. Thanks Im a GM guy also.
+Skeefoo Panama yesssir! So far, I've been able to reply to every post that I've gotten since I started this channel. I try my best to give feedback and help others out. It looks like I'll soon not be able to keep up with the flow of comments though. We'll see how it goes. Cool man! Good luck on your build! But most importantly, Keep on Wrenchin!
Great timing on this video! I have a Torsen LSD to go in the El Camino, which is also an 8.5" 10 bolt unit. Now you need to make a video on how to convert from rear drum brakes to Camaro LS rear disc brakes.
Take your old bearing and get the outer cage and rollers off the inner bearing. Take a cutoff and make a cut down the side, perpendicular to the bearing. Now you have a perfect press block for the new bearings to seat them without a hammer and punch.
We all know the 10-bolt catches a lot of flack from people, but for a sub 30" tire with a not so sticky tire, it's a good diff as long as you don't beat on your truck harder than you should.
LSDs are so nice, chucked a clutch type one in after my old single spinner turned into a UFO and wow, the car goes real nice through corners for a big car, rewards you for planting it mid corner too and can't lose the rear end in the wet(with normal driving, takes a lot of effort with the limited hp compared to the old diff). Truetrac is on the list, but 3.45s would be nice first(stock ratio, easy to get a whole diff cheap)
Yep! Preach it Wolfy! And I know about cheap. The 3.42 gears that I used in the video where free. They came out of my buddy's '94 Chevy truck. :) It origimally had 2.73s.
AGearHead4Life Looking at a factory 3.45 LSD diff with 200,000km for $2-300, cheaper than getting the gears new if the wear isn't too bad(pulled my old diff apart with 300,000km on it and it was definitely serviceable except for some heavy pitting on the pinion bearing. Problem is this city is scarce on parts, so it's more of a wait and see situation
wolfy9005 I was noticing about the same price around here when I was looking for a LSD. $250 for just the used factory posi unit. I thought that price was too high for a used factory piece. That is why i paid $135 more for a new Eaton unit, new and should be better quality. The going rate for those used units frustrates me... lol
AGearhead4Life Yeah, down here the truetrac is $900 and a set of 3.45(or other) gears is $6-900 new. Apparently the diff in mine is a Borg Warner m78, but the next model is the m80 which is a lot cheaper to get from the USA(even after shipping). I guess 250 is ok if it is a solid axle and you get the whole lot, but for an IRS center in the US it seems excessive given the abundance of parts over there
AGearhead4Life On the subject of cheap... some 2wd Suburbans (not sure which year/trim level) came with factory limited slip and 3.73 gears. The one that's currently sitting under my '83 SWB I found for $150 for the complete axle. Just another option to keep in mind for those looking to upgrade on the cheap.
Easy way to get them bearings on the carrier and fully home is to heat them up on a electric hob, until they just start to smoke (as the oil starts to smoke off) then using gloves just pick them up and drop them on the carrier. They will drop on all the way home then contract back up tight. Don't over heat them though they don't need to be so hot they turn blue. Very helpful video by the way!
So many people say not to waste time and money on upgrading a 10 bolt. I guess because of the C clips? But this just makes sense instead of trying to find a rear that will work.
Yep! Not sure why people would say that. It'd also depend on the purpose of the project. As a street truck only making around 450chp, this 10 bolt is perfectly fine. They're strong. It's the 7.5" 10 bolts that came on f-body cars that is known to be pretty weak. The 10 bolt in these trucks are 8.5" though and pretty strong. C-clips will only become an issue if you're drag racing and your setup is strong enough to break an axle.
Great videos for the guys that have never seen this done. Shame your files were corrupted. How did she sound while driving? No nasty whines I hope! Thanks for sharing!
+SuperDave21 Thank you! Yea, I was was pretty irritated to see that the files were no good once I was done. I am thankful that I had enough files to make this video though. It just sucks that a very important part was lost. But like you said, at least guys who've never done this can see how it comes apart and goes back together. Surprising, this rear end makes no noises. I daily drive this truck and beat on it pretty often, but still no noises. I expected some noise from that pattern, but maybe I'll just get some premature wear, IDK.
great video devil dog. I'm getting ready to put in Eaton posi differential in my 98 Trans Am. I'll have to send you a email on doing the backlash, this will be my first time ever setting one of these up. thank you for your service Semper Fi
+jason swiggart Thanks Devil! Nice! The Eaton is a great unit and yes that backlash can be tricky to understand the first couple times. It's also a challenge to explain through text. I'll try to help find a good article that explains setting it up. You'll need a dial indicator with mount to check it.
+jason swiggart Sorry man, had another crazy weekend. CHeck out this article: knowhow.napaonline.com/how-to-rebuild-a-gm-8-5-10-bolt-rear-differential/
great video. earned my sub. gives me a bit more confidence to rebuild my rear end on my k1500. I always like to have a general idea of what I'm getting myself Into! probably won't do it until next summer, but it needs to be done. I think it needs gears and all. clunks when you put it in gear. and no it's not the ujoints! changed them already haha! 250k on original rear I have no complaints.
I just stumbled across your video and I have to say it was a fantastic instructional. Thank you. Additionally, I also do a lot of my mechanic work in my OSHA approved flip flops..... we could hang out.
I know you're on it brother, just giving you the business Devil Dawg. I got my Yukon duragrip and 3.73's in and I am trying to absorb some knowledge before I get greasy.
I had a hydraulic pump from a 5020 John Deere come off the bench and land on my foot. After x-rays I hobbled downtown and bought steel toed boots. Nice flip flops...
No sweat man . perfect info for me atleast! great video . thanks . rebuilding my rear axel on a 1979 g20 nomad next winter , also have a 1969 chevelle malibu with a 12 bolt posi , and my dad have a 1966 GTO with a 10 bolt posi he ripped apart on the track ...
That's actually a vice my friend, not a press. But regardless great video I've been subbed for a long time this is awesome 👍 very thorough and much appreciated.
Excellent video, I will go looking for more of your videos now, love the way you explain stuff. Sorry to hear about the lost content that would have made this series perfect. I noticed you had a bit of back light problem making it hard to see inside the diff, next time just use some cardboard or tarp to block the sun that's peaking in, or you could put a shop light behind the camera, either way would rid that problem. But I'm just nit picking now. So if I have a 12 bolt GM diff is the process similar, exactly the same or is there something I should look out for? Thank you very much for a great resource video. Thumbs up!
gReG sKi Thanks gReg sKi! Yea lol that's pretty much what I did. I had cardboard up and a light behind the camera, but I guess it was still too much sunlight or not enough cardboard to block it. It got more clear later as the sun went down I guess. This is one of the downsides to using a gopro. I dont alwasy get the best preview since its not on the camera its self and readily available. That and then aslo rushing to get the job done so that I can drive the truck to work. Trying to think about finishing the job, narrate and camera angles can be overwhelming. Oh well, with each video I make, I learn more. Thanks for looking out with the tips! The 12 bolt would have a lot of similiarities but I'd bet that the torque specs may be slightly different.
Thanks Tyler! Yea, it seems to be a quality piece and I have really been enjoying it. Its hard to put into words how it has improved my traction. not just becasue both wheels are turning now, but how they're applied is awesome.
I'm looking for the Turbo LS build video the Camaro will be nasty on boost. Wish I had space under my S10's hood not much room for anything really so I will stick to the N2o for now.
Yea, I really need to get that update video together this weekend. I don't have much progress to show. Just the begining of the turbo hot side and the heads being bolted down. I need to finish up that piping asap. If you went boost on that S10 you'd have to mount it in the passenger seat! lol I think I saw a guy on youtube put it in the bed of his S10 once.
I was thinking lockers, then thinking 4 electric motors one on each wheel! Biggest they make, Big 3 phase generator to replace transmission! 2 Front motor gas pedals on left side and 2 for rear on right side! Wouldn't that be a blast? Individual control of all 4 wheels or step on all 4 pedals for 4 wheel independent drive!
Thanks Steve! Glad you're enjoying it man. I'll likely be turning this YT channel into my own show very soon. I'm transitioning out of the military now. Time to find a new living and it'll likely be this.
Remeber that the Eaton truetrack has a different bearing radius than the factory dif. So you need to buy the install kit to fit for it. Don't buy the standard rebuild kit. The bearing radius is about 1mm too small.
Very well produced video. Great grammar- no "uhhhhhs" and "ummmmmmmms" every few words which is very annoying and makes you loose track of what's being explained. Thanks!
I agree 100%, so much nicer then 90% of 18yr old youtubers lol.. Love what you do, I have a 79 c10 and a 79 k30 so its nice to see what others are doing!

Putting bearings in the oven makes it expand and slip right on. The opposite for races. Freezing shrinks the metal. For those that may be new
At what temperature and for how long? Thanks!

That's assuming the carrier you're using will not affect the gear pattern and you can get a proper backlash at the same time.

I didn't think you'd reply, thanks. I'm doing the same thing your doing thats how I found your video. I'm going from a Muncie 4 speed to a Tremec 6 speed and installing an Ectec locker. Thanks Im a GM guy also.
+Skeefoo Panama yesssir! So far, I've been able to reply to every post that I've gotten since I started this channel. I try my best to give feedback and help others out. It looks like I'll soon not be able to keep up with the flow of comments though. We'll see how it goes. Cool man! Good luck on your build! But most importantly, Keep on Wrenchin!
Great timing on this video! I have a Torsen LSD to go in the El Camino, which is also an 8.5" 10 bolt unit. Now you need to make a video on how to convert from rear drum brakes to Camaro LS rear disc brakes.
Thanks Rick! I may wind up doing that conversion if I find out that I can fit my 15" rally wheels over those brakes.
ua-cam.com/video/0z79D14fyQk/v-deo.html here you go Rick. He did most of the conversion in real time
Thanks, Victor! That will be very helpful. Now, if you could do something about this cold weather....
@@AGearHead4Life Camaro brakes have wrong bolt pattern. Use 94-96 Caprice/Impala
For truck 5X5" bolt pattern or 79-85 Seville
Thanks brother for yer time and effort doing this. Big help.
Thank you for your service! God bless you and your family!!🤝🤙🏼
Thanks for the vid and links Marine, gona buy this so I can install on my 78 Nova rear 😎
Take your old bearing and get the outer cage and rollers off the inner bearing. Take a cutoff and make a cut down the side, perpendicular to the bearing. Now you have a perfect press block for the new bearings to seat them without a hammer and punch.
mark your shirt is a killa man got it on now got my eye on a 6.0 truck motor thanks bro
+Rick Wilson Thank you Rick! I'm glad to hear that it got there. Good luck on the 6.0 hunt!
Man I really love all of your videos keep up the great work I learned so much from you thanks
We all know the 10-bolt catches a lot of flack from people, but for a sub 30" tire with a not so sticky tire, it's a good diff as long as you don't beat on your truck harder than you should.
my bad bro didn't think of readying the description lol
lol No problem
Thanks for the video, & even bigger thank You for your service in the USMC
Awesome USMC tattoo, thank you for your service
Thank you Chris!
LSDs are so nice, chucked a clutch type one in after my old single spinner turned into a UFO and wow, the car goes real nice through corners for a big car, rewards you for planting it mid corner too and can't lose the rear end in the wet(with normal driving, takes a lot of effort with the limited hp compared to the old diff). Truetrac is on the list, but 3.45s would be nice first(stock ratio, easy to get a whole diff cheap)
Yep! Preach it Wolfy! And I know about cheap. The 3.42 gears that I used in the video where free. They came out of my buddy's '94 Chevy truck. :) It origimally had 2.73s.
AGearHead4Life Looking at a factory 3.45 LSD diff with 200,000km for $2-300, cheaper than getting the gears new if the wear isn't too bad(pulled my old diff apart with 300,000km on it and it was definitely serviceable except for some heavy pitting on the pinion bearing. Problem is this city is scarce on parts, so it's more of a wait and see situation
wolfy9005 I was noticing about the same price around here when I was looking for a LSD. $250 for just the used factory posi unit. I thought that price was too high for a used factory piece. That is why i paid $135 more for a new Eaton unit, new and should be better quality. The going rate for those used units frustrates me... lol
AGearhead4Life Yeah, down here the truetrac is $900 and a set of 3.45(or other) gears is $6-900 new. Apparently the diff in mine is a Borg Warner m78, but the next model is the m80 which is a lot cheaper to get from the USA(even after shipping). I guess 250 is ok if it is a solid axle and you get the whole lot, but for an IRS center in the US it seems excessive given the abundance of parts over there
AGearhead4Life On the subject of cheap... some 2wd Suburbans (not sure which year/trim level) came with factory limited slip and 3.73 gears. The one that's currently sitting under my '83 SWB I found for $150 for the complete axle. Just another option to keep in mind for those looking to upgrade on the cheap.
Great video. Straight to the point.
Mark,Nice job as always my friend !! Now we need Burn-out videos !!!!!!!!
Yes we do! Tires are still in the bed waiting to be finished off.
Easy way to get them bearings on the carrier and fully home is to heat them up on a electric hob, until they just start to smoke (as the oil starts to smoke off) then using gloves just pick them up and drop them on the carrier. They will drop on all the way home then contract back up tight. Don't over heat them though they don't need to be so hot they turn blue. Very helpful video by the way!
+Max Williams Thanks Max! and good tip. Thanks for sharing!
I used to put the carrier in the freezer and the bearings in the oven they practically fell on
Put them in the microwave wrapped in a wet paper towel and they go on super easy after.
This video is the answer to my prayers brother!! Thank you!
27 people need there finger broke lol.thanks brother for taking the time to show us how to do this .rear end have always been my weak spot
+William Swanson Thank you William! Good luck!
great video. got the confidence I need to embark on replacing the differential gears on the 3/4 Cheyenne. thanks
So many people say not to waste time and money on upgrading a 10 bolt. I guess because of the C clips? But this just makes sense instead of trying to find a rear that will work.
Yep! Not sure why people would say that. It'd also depend on the purpose of the project. As a street truck only making around 450chp, this 10 bolt is perfectly fine. They're strong. It's the 7.5" 10 bolts that came on f-body cars that is known to be pretty weak. The 10 bolt in these trucks are 8.5" though and pretty strong. C-clips will only become an issue if you're drag racing and your setup is strong enough to break an axle.
Th 8.5" and larger are good to 1000HP. The smaller ones are what gave 10 bolts the bad rep.
Let them keep saying it so there are more for us. I got no problems with my 10 bolt performing
all of your videos are very informative good job
+dillon myers Thank you for your feedback Dillon! I'm glad that you're enjoying them. Keep on Wrench'n!
Great detail--thanks for sharing!
USMC Ron great video! Semper Fi
awesome videos man. i really like how you speed up the video when needed
Thanks Matt! And thanks for the feedback!
Great videos for the guys that have never seen this done. Shame your files were corrupted. How did she sound while driving? No nasty whines I hope! Thanks for sharing!
+SuperDave21 Thank you! Yea, I was was pretty irritated to see that the files were no good once I was done. I am thankful that I had enough files to make this video though. It just sucks that a very important part was lost. But like you said, at least guys who've never done this can see how it comes apart and goes back together.
Surprising, this rear end makes no noises. I daily drive this truck and beat on it pretty often, but still no noises. I expected some noise from that pattern, but maybe I'll just get some premature wear, IDK.
Another excellent video Mark!
Thank you Marcus!
hey man great video. looks a lot easier than i thought. i definitely want to do this to my 99 Dakota R/T sunday warrior
Thank you! Make sure that you study setting up the gears and crushing the crush sleeve before starting.
great video devil dog. I'm getting ready to put in Eaton posi differential in my 98 Trans Am. I'll have to send you a email on doing the backlash, this will be my first time ever setting one of these up. thank you for your service Semper Fi
+jason swiggart Thanks Devil! Nice! The Eaton is a great unit and yes that backlash can be tricky to understand the first couple times. It's also a challenge to explain through text. I'll try to help find a good article that explains setting it up. You'll need a dial indicator with mount to check it.
Appreciate it I'll be picking one of those up today. My differential should be arriving this evening so will be starting on it possibly tomorrow
+jason swiggart Sorry man, had another crazy weekend. CHeck out this article: knowhow.napaonline.com/how-to-rebuild-a-gm-8-5-10-bolt-rear-differential/
great video. earned my sub. gives me a bit more confidence to rebuild my rear end on my k1500. I always like to have a general idea of what I'm getting myself Into! probably won't do it until next summer, but it needs to be done. I think it needs gears and all. clunks when you put it in gear. and no it's not the ujoints! changed them already haha! 250k on original rear I have no complaints.
+nitrosport5 Awesome man! Welcome to the show! Good luck on the rear end rebuild. Make sure that you study setting up the gears also.
nice to see some more vids from you . merry cristmas and happy newyear from the netherlands
Thank you! Merry Christmas and a Happy New Year to you also! Be safe!
Use the press if you have one that's what it's for ☺️ welldone mate
Your like David Freiburger with the flip flops going on, good video by the way
Thanks for the video! Great quality and learned a lot! Semper Fi!
I just stumbled across your video and I have to say it was a fantastic instructional. Thank you.
Additionally, I also do a lot of my mechanic work in my OSHA approved flip flops..... we could hang out.
Ur videos are very helpful an informative bud . Ur awesome bother keep on making videos .
+bigdogac1 Thank you bigdogac! I appreciate your feedback!
I know you're on it brother, just giving you the business Devil Dawg. I got my Yukon duragrip and 3.73's in and I am trying to absorb some knowledge before I get greasy.
Marcus Lovelace mmm u. o dc
I had a hydraulic pump from a 5020 John Deere come off the bench and land on my foot. After x-rays I hobbled downtown and bought steel toed boots. Nice flip flops...
Thanks! Theyre just cheapo old navy flippy floppies. Did you ever finish the Jon Deere?
Yep, that was my job 50 hours a week
ah damn! That's a lot of pumps!
I'm telling you that set my eyes to watering ;)
No sweat man . perfect info for me atleast! great video . thanks . rebuilding my rear axel on a 1979 g20 nomad next winter , also have a 1969 chevelle malibu with a 12 bolt posi , and my dad have a 1966 GTO with a 10 bolt posi he ripped apart on the track ...
Fabulous work. Thank you for sharing!!!
That's actually a vice my friend, not a press. But regardless great video I've been subbed for a long time this is awesome 👍 very thorough and much appreciated.
I love flip flop mechanics.
Lol
Good video. I couldn't wear flip-flops however because it seems I am always dropping or knocking something off the bench, lol.
+Greg Beckham lol Thanks Greg! Yea, I'm waiting to see how long it takes for me to learn my lesson.
Mother playing in the background nice
Excellent video, I will go looking for more of your videos now, love the way you explain stuff. Sorry to hear about the lost content that would have made this series perfect. I noticed you had a bit of back light problem making it hard to see inside the diff, next time just use some cardboard or tarp to block the sun that's peaking in, or you could put a shop light behind the camera, either way would rid that problem. But I'm just nit picking now. So if I have a 12 bolt GM diff is the process similar, exactly the same or is there something I should look out for? Thank you very much for a great resource video. Thumbs up!
gReG sKi Thanks gReg sKi! Yea lol that's pretty much what I did. I had cardboard up and a light behind the camera, but I guess it was still too much sunlight or not enough cardboard to block it. It got more clear later as the sun went down I guess. This is one of the downsides to using a gopro. I dont alwasy get the best preview since its not on the camera its self and readily available. That and then aslo rushing to get the job done so that I can drive the truck to work. Trying to think about finishing the job, narrate and camera angles can be overwhelming. Oh well, with each video I make, I learn more. Thanks for looking out with the tips! The 12 bolt would have a lot of similiarities but I'd bet that the torque specs may be slightly different.
Nice pair of flip flops 🩴 you have there!
Nice work and unit, you should have no problems with the Truetrack.
Thanks Tyler! Yea, it seems to be a quality piece and I have really been enjoying it. Its hard to put into words how it has improved my traction. not just becasue both wheels are turning now, but how they're applied is awesome.
I'm looking for the Turbo LS build video the Camaro will be nasty on boost. Wish I had space under my S10's hood not much room for anything really so I will stick to the N2o for now.
Yea, I really need to get that update video together this weekend. I don't have much progress to show. Just the begining of the turbo hot side and the heads being bolted down. I need to finish up that piping asap.
If you went boost on that S10 you'd have to mount it in the passenger seat! lol I think I saw a guy on youtube put it in the bed of his S10 once.
I was thinking lockers, then thinking 4 electric motors one on each wheel! Biggest they make, Big 3 phase generator to replace transmission! 2 Front motor gas pedals on left side and 2 for rear on right side! Wouldn't that be a blast? Individual control of all 4 wheels or step on all 4 pedals for 4 wheel independent drive!
killer video man exactly what I needed to see !!
Videos are damn good,thanks for making these helpful tutorials. Keep up the good work sir gear head!
Thank you RedDevil!
Brother why ain't you got your own damn show yet! Thanks GREAT info every time!
Thanks Steve! Glad you're enjoying it man. I'll likely be turning this YT channel into my own show very soon. I'm transitioning out of the military now. Time to find a new living and it'll likely be this.
AGearHead4Life "salute!"👍🏽🙌🏽🍻
I just purchased this same posi with 3.73's for my 96 impala ss.
+MrFrankwite1 Nice! You're going to love it.
+AGearhead4Life I surely hope so can't wait to lite the tires up
Great video Mark!
Thank you Davie!
Remeber that the Eaton truetrack has a different bearing radius than the factory dif. So you need to buy the install kit to fit for it. Don't buy the standard rebuild kit. The bearing radius is about 1mm too small.
Great video sir! Very helpful when i work on my 01chevy silverado
Alexander Lara Thank you Alexander! Good luck on the Silverado!
Semper Fi Gear head, nice vid!
Very well produced video. Great grammar- no "uhhhhhs" and "ummmmmmmms" every few words which is very annoying and makes you loose track of what's being explained. Thanks!
Glad to hear it MickeyMoe! Thanks for the feedback.
I agree 100%, so much nicer then 90% of 18yr old youtubers lol.. Love what you do, I have a 79 c10 and a 79 k30 so its nice to see what others are doing!
thank you very very much. Upgrades coming soon!!
+syscocar Awesome! Good luck!
Good video. I’m gonna install one on the tail of my 4x4 85 Chevy K10. Semper Fi
