Today we are looking at the failure of C.V. boots. I have replaced a ton of boots over the years. Even a few on my own personal VWs. I might even say they are maintenance. These boots may also be called axle boots

Reminds me of a funny incident while attempting the removal of the cv bearing by whacking it with a rubber mallet, the bearing suddenly came off along with all the balls which rolled down the driveway and into the street. I ran after them before they'd a chance to slip away into the wooded area across the street and luckily managed to retrieve them.
I was just finishing changing my outer CV boot a few minutes ago and when I was tightening the second clamp, I realized the inner CV boot is also bad, nothing beats doing the same thing twice
A couple years ago, I got the clicking, so I looked and both boots were torn. I had them replaced at the local mechanic, and the one on the right rattled whenever I went over a bump (another garage had said it was probably the remanufactured brake caliper that had been recently installed). So, they replaced that one, and the sound was even worse, so they replaced it again. It seems to be OK now. Last week, I had just about gotten home and I heard a noise exactly like a seal barking (as in, the sea creature), and when the noise happened, it pulled to the right (I think). I stopped and I tried to turn the wheel all the way to the right to look at the left axle and I couldn't even turn the wheel all the way! So I backed up a bit, was able to turn it, and saw the split boot on the left axle. So I had the car towed to the mechanic and sure enough, it was the left axle. The mechanic said he'd never seen one fail that way! I'm glad it failed right by my house when I was going 10 mph and not on the highway!
Great video. This seems to be an issue across all brands, like you said. I had a Subaru Outback that had a torn boot and the grease went all over the exhaust so I could smell it burning right away. Some think that the placement of the exhaust so close to the boot causes premature failure, but I'm not sure since this seems to happen to a lot of cars.
great info! im doing axles this weekend on my my 97 gti. should be pretty quick!
157k miles in my 2008 mk5 gti and will be replacing my driver axle because it’s been clicking. Boot still looks good though. Is that odd? Legendary boot I suppose lol
Love your videos! I’ve been watching A LOT of your stuff these last two weeks!
My go to Car guy... Was trying to explain how but I wasn't getting through. So naturally I have been able to turn it over to you..🎵 appreciably said and done..Thanks
🙏🙏🙏🙏🙏
Tiguan 2011 does vibrate heavily on the highway and I also noticed the vibration when I am fully turning the vehicleto the right on reverse or on a U-turn. I will sure to look under. If its not leaking could it wear out? I am at 138K on tiguan. Thanks to you few DIY are keeping it going.
Thanks for the explanation, I got the rubber broken close to the little ring. As you explained, just beside the ring. And grease have come out. My question. Can I drive 2000km, before gettting the reparation?
Thank you do much!!! This was great.
Thanks for this post..i am a new owner of a 2004 Jetta tdi.unreliable key fob operation baffled me . After your post I checked voltage on my new batteries. 2.9 volts. Now if i can just get rid of that check engine light…..
Great video as usual bro!!! Did u do a video on how to remove the axel that you have in this video?? The 18 Tiguan has this axle with spline on the transmission side I have to swap out and I don’t want to damage the transmission please...
I got one failure for ya. Purchased a 2000 vw beetle for cheap, and noticed how the suspension would pop. Grill is busted on drivers side, and fender has a crack close to the headlight. This car was sold to me as a project car. I looked under it a couple of days ago and what I found kinda surprised me. I've not seen this kind of problem before, but I'm sure someone must have. It looks to me like the previous owner went over a curb or did a dukes of hazard, but I'll bet they went over a curb. The strut has pushed through the steering knuckle and got into the boot of the cv joint! I've never seen anything like that before. Gonna replace the shaft and the struts. I haven't torn it down yet, so I don't know if I'm gonna need to replace the knuckle but I just thought it was worth mentioning this as another way a cv boot can fail.
Hi Charles, I have a 2013 Touareg TDI and the rear CV axle outer boot split like you described. The repair manual says to that you should use a axle puller jig to remove the axle once you have the upper suspension arms, lower strut mount, and lower rear suspension arm removed. Then you swing the hub assembly out while you use the puller to push the axle through the unit bearing. Can a standard auto puller work instead? Seems that you can pull the rotor, and then press the axle out using the unit bearing hub as an anchor point.
Hi humble mechanic, what are signs and symptoms of failure steering rack boot (tie rod)?
Thank you for sharing this important information listening from Brownwood Texas
One of my boots needs replacing, thinking is replacing all 4 and gearbox shaft oil seals. Will this be a wize move? 2002 vw jetta tdi. Looks like the original parts still. 340k kms
Good video, thanks. Any way to reduce the chances of tearing or a way to reseal the cuts with some kind of special material sealant? 2 Honda's now each with a far turning radius that probably exceeds and strains the outer boots stretching ability. Each vehicle with about 4 torn CV boot replacements, once every few years, which costs a good $300 to fix each time and takes hours for them to complete the time consuming task.
hello there... i have a problem keeps on happening with my VW bora 1998 the CV joint keeps on breaking ... i changed it 3 times in 2 years i wonder why or have i made a mistake?
Just got my clutch & flywheel done, 2 days later I notice brown grease absolutely everywhere. Probably cut the CV boot when they were taking everything off
Thank you! Dealership found a tear in mine.
can you reuse the 6 inner flange bolts, the ones that secure the cv axle to the differential, or they have to be changed every time? I have a cv axle to replace tomorrow.
My daily drive is a passat b5.5 tdi replaced alot of cv boots door locks and window regulators same to be the weak points but i like how they drive
My wife's 07 beetle has broken outer boots. Is it common to just replace the boots or should I replace the whole axle? About a month ago I walked under the car and noticed the boots but I don't know how long before that they had been broken.Thanks
thanks. what kind of boot material will last the longest? i'm tired of replacing those cv boots. can't find the origianl. im looking for a sturdy material any ideas??
Number 1 reason why they split today? Boot quality.
Hi, how to regrease/put fresh grease into the CV joint? Thanks
Do you think Rein makes a good quality outer cv boot kit for the B5.5? Or, do you recommend another supplier (GKN) or VW original?
I get a humming sou d when I accelerate through a corner? But if I clutch during the turn the humming goes away? Only when turning full lock to the left though? Any ideas?
Passat b7 2.0tdi 145bhp
2011
“How Good Documentation WILL Make You a Better Technician” notification came up while watching this 😏🤙🏽
What about a rubbing/humming noise when I turn the wheel just to the right? No clicking, but I'm being told I may need a whole new axle. Vehicle is a 2012 GTI with DSG base
How do you remove that spline with the clip on the drivers side axle on a MK7.5 Golf S? Tried pry bars, cv puller is too thick to put in-between the transfer case and the cv, no luck.
Hey I got a question my 2006 VW Passat 2.0t is shaking while acceleration between 30 and 45 mph any ideas? I appreciate any help, thank you.
anything we can lubricate the boot with to maintain elasticity to prevent it drying out/cracking?
Silicone lubricant
I wondered why I never heard of Hondas or Toyotas ripping boots - so I had a look at one and compared to vw - it looked simply like they had more “accord”ian folds and they didn’t stretch out as much as on the BW so on VW I would relocate the inner clamp 1cm closer to the wheel hub so the folds wouldn’t fully stretch out - only changed boots once on the car - I did this twice on two Jettas and never did the boots again !
Remove the inner axle end boot clamp. It is not needed. I've not used them in decades. The boot fits very snug over the axle. This will allow for the boot to settle over time and not over stretch pleats while rotating. I'm going to be doing this job here today, the last time I did it was 1998. I used no clamps on the axle end of the boot. Using Rockford boots this time. The beveled washer was eliminated as well by VW via tech bulletin years ago.
i have an 08 civic i have replaced the axel on both sides ones and also the boots 5 times....
What is velocity joint gater and where is it and how much is it cost part and labour pls for golf gti 2005'volkswagon many thanks
Ran over two pallet jacks on the freeway cracked a rim and knocked the boots off i just bought two new cv axles on my vw rabbit 2007 one question i had is when buying a new cv axle from napa they come with boots and clamps so should i grease those new cv axles?
For all of you who own Audi A3 3.2 V6 DSG and possibly Golf R32 with the same engine it's very important that your inner passenger side boot is the propper size. If it's too big it will touch the engine's edge right at the top of the oil pan. Normaly the inner boots are slimer in diameter than the outer ones.
Great videos. I own an 08 B6 BPY and have done many DIY repairs. This one was tricky and I couldn't get the axle free from the transmission. Do you have a "how to" on removing the axle with the PITA snap ring?
Sometimes its worth doing the boot on the car. LOL. those can suck!
@@HumbleMechanic I need you help please I have a Audi s3 8v and I’m having clicking noise on driver side when turning right and left and also hear a clunk noise to
Mine split at the end of the boot like you said. And yep loads of clicking
Yikes. Time for a rebuild or a new joint
Just finished rebuilding cv joint. I didn’t get grease with the kit but I do have lithium grease. Will that do ?
When this happens in my cars I just replace the axle so there’s no chance of any dirt or damage to cause issues in the near future
Axle is very expensive, while just rubber is about 10 euros.
FYI, it is called a CV joint because it is, unlike a universal joint, designed to have the input angular velocity equal to the output angular velocity all the time....hence, constant (angular) velocity. If you think about it hard enough, the regular U-joint only has 'constant velocity' when the angle of bend is zero (perfectly aligned input and output shafts). At any bend, the 'cross' wobbles around and generates sinusoidal components of angular velocity. In the old days, we didn't care. We drove Scouts and Blazers and Broncos....we couldn't feel subtle vibrations. But then cars got fancy and refined and no one wanted micro-wobbling in the steering as we evolved into front wheel drive.....
Boss… I rode my cv axle with a broken boot for quite the time.. yesterday night I took off for a drive and as soon as I hit the main road by making a right turn, the car just jerked and shut off. I immediately placed it in park and turned the key to off. Now it turns on but cracks and rattles when I place it in drive or reverse, and it won’t drive at all. Is it my cv axle gone completely broke? Or can it be my transmission? No check engine lights. Engine turns on perfectly and revs great. But as soon as you place it in drive, it rattles, cracks etc and won’t drive just shake a lot. Shakes so much my side view mirror fell off…
I have a 93 corolla atm japan import, can i use USA drive shaft to replace my bad one? the import is right hand drive and USA is left. vin is AE100-003234 or AE100-AEHNK
I need to replace an outer boot on my B6 do you have any tutorials or videos of the repair as this is one diy I have never done
Sadly no. It's a pretty easy boot to replaced, as long as the inner joint comes out of the transmission
Thanks for all the great vids 👍🌮....my axle boots are split on both sides by the clamp and in the center on my b6 passat wagon with 98k ..with the mileage on the car should I just change out whole cv axle? your opinion would be greatly appreciated ..
Jess Hicks same issue with my b6 Wagon; both sides are shot and I’ll try clean and regrease the joints without taking them off, just replacing the clamps. Hopefully it will fix the clanking sound when shifting at low speed.
What tool could I use to remove my axle 2.5 Jetta 2012
How about a mysterious shimmy under acceleration sometimes ,no noise
Is it more like a wobble then a shimmy
Why are the cv shaft bolts so hard to get loose?
Damaged four PCs of 3/4"-1/2" adapters.
Bent my trusty 1/2" heavy duty knuckle bar.
Emptied a bottle of burner gas.
Impossible to loosen up.
Have done this job on several other cars, no one as difficult as this b6
Are they mounting everything without antiseize compounds.
I’m having a clunking sounds when on bumps, this happens after replacing the inner cv boots. Any idea what’s going on with it? The mechanic told my it’s my suspension issue, but it didn’t make a sounds before the replacing.
Im expiriencing same problem ryt now ,2 weeks back i changed all cv joints but there grinding noise and all parts on suspension are new.(polo vivo sedan)
Jetta MK3 1994 1.8 petrol 90hp known as Vento in EU. First there was continuous slight treble and tremor for two years. Absolutely impossible to locate. I was lone soul to consider it as serious symptom because of my very sick sensitive back for such things. In peridoc inspection officer found CV boot broken(which was replaced). Ok one day after 2 years of continuous tremor I was driving straight ahead and started to hear ryhmic clips like wire touching(jumping) on some wheel rims. That was locateable to the front left. That sound was beginning of the end of that left drive shaft tire end. Last symptom was actual wobbling in steering and then self repairing once and finally all the bearing balls had shooted out from the structure. I was 500m from home so we managed tow it to neighbor. I'm quite lucky because my neighbor is a resourceful man. Would it be possible that that broken boot had gone broken because one of the bearings' ball would have shooted out and rest of them left kind of working? I have no real idea what is possible there considering forces. But at least lesson to learn might be:"If there is slight mystic unlocatable trembling plus visual damage in CV boot you better swap the drive shaft".
What happens if only when you are going in reverse you can hear the clicking?
My damn C5 RS6 tears the front axle boots twice a year. Being lowered (not slammed) doesn’t help, but it’s annoying AF at this point.
Thanks a lot! I have a 2012 beetle. Do you think is this a complicated DIY or doable?
It’s totally doable
Would a bad cv stop my car from moving??
Mine is keeping get torn after just 1 month I don't how to fix that.. audi a3 8p 2007
Hi Charles did you notice That on mk5 VW the car That has the most failure is cars with the DSG and it is allways the outer CV' boot left and the boot is allways torn close of the small clamp where I'm from it gets verry cold in the winter I wonder in places were it get hot all the time does the boots last longer ? I would say yes.
V10PDTDI We don't see them on the DSG as much as the auto trans. But it is usually the left outer boot, and it's split on the inner clamp. Here in the south US we see them pretty regular.
Thats an interesting observation - it's exactly whats happened on my car; Mk5 DSG7 and it's LHS outer boot, small clamp which is gone - the other boots are OK.
If the boots on the inner joints are torn, can you pull the axle, clean the triple roller, and just repack and reboot it? How do you know if your inner cv/triple roller is not reusable, and if it's worn/damaged? I'm getting slight vibration while accelerating from a stop which smooths out at about 15mph. My outer boots are good, inner boots are trashed, and I'd rather clean and reboot if I can instead of getting all new half-shafts.
Odds are the inners are worn that’s causing the vibration. However it may be worth the work to try and reboot them before replacing the whole joint or axle
I had my cv boot exploded open on the highway. My left front rim was completely coverd in black grease on the inside... cleanup was not fun haha
No that cleanup is never fun!
wow, you're like a wizard!, it's exactly what happened on my mk5 but we didn't checked/knew(bought it used):
we where getting clicking noises on turning but it was difficult to know where from, and we left it as is, sometime later i don't remember why we had it checked... CV boot was split in the accordeon, totally dry and the spline joint to the wheel hub was completely destroyed, it had grinded itself flat and the clicking was the axle bouncing around so we where driving a 1-wheel drive car for quit sometime(weird i though the diff was open in these cars).
Had to change sheel hub, axle, cv, all the package, less than a year later it split in the accordeon again.....
Isn't there an improved part that uses the had rubber for older cars?
Could you lose the front tire if the boot is split and all the grease is gone.
odds are no, but it can do much more damage.
My vw shakes from front end when driving under 40mph when going 50mph or more its drives fine what could it be thanks
Same problem on my
Sounds like an unbalanced tire.
Probably tires out of balance - could be stiff (dry) cv joints - as explained in the video look for wet dark blueycarcoal or greenycharcoal grease at the boot behind the wheel hub AND at the boots where they are connected to the transmission. If you have vibration while braking it’s most likely the brake rotors are warped
One of my CV boots got cut open by a string of dental floss that it picked up on the road LOL
Weird and for you drivers out there don't floss your teeth in the car and throw it out the window that is just rude and can cause Cv boot damages!
Yep! Flossing in the car and throwing it out the window is rude, nasty, and destructive LOL
Fucking crazy lol
My 2014 beetle shakes on the rear end
if one side is leaking is it recommended to replace both?
Saigonboi 23 no
thanks
⭐️👍
Came here after finding my mk7 with 7000 miles on it had slung grease all over my fender well and underside of transmission.
WOW that sucks!
My b5.5 is a suspension nightmare. The guy before me put fully adjustable coil overs on the car. Which would be fine, except that it's changed the geometry in such a way that a hard turn will smash the cv boot against the lower aft control arm and rip it open. I have replaced three on the right side already and 2 on the left. Right now I'm facing replacement number 4 on the right. Currently I'm stripping down the entire front end on my wrecked 03 to put on my 01. Because f**k it, I'm not doing it anymore. I will send that goofy coil over suspension back to the great lake of fire from whence it came. It also eats front end tires like a banshee. Oh yeah, and wtf is with that retaining bolt for the upper control arm linkages, it will not back out on either side for both cars. Instead I'm dropping the whole assy and using a press to get the bolt out.... that's 4 entire assemblies! Autodoc can shove that bolt up his silly German arse, mr. Tappy tap tap with a hammer and it's out guy. I'm over this freaking car.... wait nah she's still good, I'll take her back, no one else understands her.
Damnnnnn, 50k (avg) is A LOT. I don't get why dubs need maintenance so often on many of their parts.
MrSlowestD16 All part of the fun? ;)
My 03 VW has over 400K miles and only have replaced the inner boots once, the outers have not failed at all.
Just replaced my first in one at 95000 miles on my citroen c3 Picasso
John Be Bad - if you avoid lock to lock turns boots will last a long time
VW's are not well made cars.
0:23 I own a failed VW!
172000tkm for me. mk6 golf tdi
YA! YA! YA!
