CV Boot - how hard to replace

My inner CV boot is torn...I know it takes a 6mm allen bolt. Is there a trick to replacing the inner CV boot or does the entire axle have to come out?

Also, Where is the number on the tranny as I understand there is a difference in CV boot's for the carrera's

Thanks in advance....

The axle comes out and it is that much easier to do.

The inner one is the easiest, luckily. Just remove the bolts securing the axle to the gearbox flange and then remove the retaining ring that secures the CV joint itself to the axle and the hole thing will pull right off.

While you're in there, I would highly recommend disassembling, cleaning, inspecting and re-packing the CV joint. Not too bad of a job. Just messy.

i did mine on my sc w/o removing the entire axle. i dropped it down off the flange from the tranny and suspended it with a metal hanger, or tie wire if you please.

i was able to remove the CV boot and clip wioth out much trouble. thing is that you will knock/dislodge alot of dirt and pebbles working under there so i made sure to start with fresh cardboard prior to reassembly the 2nd time. the 1st time i dropped some parts down onto the carpet i was working on and got a ton of S in the fresh grease. had to start from scratch with the cleaning and reassemble.

it is my understanding that the carreras in order to remove the entire axle you need a monster socket to actually remove the splined gears from inside the hub. i think your drop and fix in place makes the most sense. a memeber cbeers did the job on his carrera and if i recall the hub nut takes a wicked amount of torque.

True enough. To take out the whole axle, you will need a hefty impact and a big socket ( I forget the size). Not to mention a BIG torque wrench to reassemble.

For yours, simply follow the guidance above.

The difference in axles has to do with diameter, there is a cut off somewhere around 1985-6, you will have to look that up or wait for someone to chime in with the specifics.

KQW,

The earlier Carreras through 85 had 100mm axles, the 85-89s had 108mm.

Go figure.

See PP catalog for more info.

Thanks again guys.....Going to tackle the issue....I'll heed the advice of just dropping the axle from the tranny end and suspending it while I work.

By the way is the torque on the bolts 60 ft/lbs..?

I can't remember, check the Bentley manual for specs.

Then, when you have driven it around again, check them to be sure they are still holding tight.

Good luck!

Since I have 4 boot kits sitting on my kitchen table to be installed on my '88, I'd like to ask how much grease? Each kit has two packs of 80 grams yet Bentley says 80 is the amount to use for each CV. What am I missing?. Do you just pack the CV or into the boot as well? Thanks, Ken

Well folks...

Got everything off and ready to put the new boot on...I must say I had to fish through my tool box to find the correct "C" clip extractor tool because without it that clip is a bit%^h to get off...

IROC...yes, cleaning the CV up is a necessity as extracting it is a mess and the CV gets contaminated.

KC911...that thread was right on the mark.....

Chris and Yelcab1...your advice made the job MUCH easier...Thanks...

Tigerrat...I'll let you know the amount of grease as right now the CV is soaking (cleaning) ....

I plan on stopping by my wrench in the morning and I'll inquire about the correct amount of grease and packing procedures as "while I'm at it" I plan to re-pack all the CV's...

Thanks all for the excellent advice....

Just an update...

Apparantly the parts supplier had a difficult time getting me the correct CV Boot. Mine has the heavy metal flange connected to the boot not the boot that is attached with a clamp...Sooo it will arrive on Friday...

Tigerrat...I'll let you know the amount of grease once I pick up the boot...

Thanks

Funny, I just ordered new boots for my car. Mine's an 85, so there was some debate as to which axels I had. Turns out the best way to tell is by tranny number - 915/68s have the old 100mm axels, 915/70s (I think) have the newer ones. My car is a solid 85.5 (Feb build date) but still has the old 915/68 tranny and axels.

Yes Chirs...I found out after the CV boot I picked up on Tues. was not the solid flange like my original.

I think your car may have the same boot so make sure you get the right ones. It seems that many parts suppliers including our host has a bit of confusion on the right ones.

I have a feeling that with the warm season coming up and folks are getting up under their cars, those boots will be on back order soon...

Have you replaced your boots before?

Kqw - Thanks for checking on the grease. So did you pull the axle or were you able to remove the inner CV's under the car? I made reasonable effort to "tap" the CV off the axle and got no where. Unless you or someone has another idea, I'm looking at pulling the axle. Ken

Thanks..

Since my damaged boot was the inner (tranny side) I was able to remove the CV quite easily. The "C" ring holding the CV on the axle was a minor challange but I had the right tool to expand it/remove and take the CV off and then the boot.

All my other boots are in good shape but I want to re-pack the other CV's. With time not on my side I may finish replacing the damaged boot and next weekend tackle repacking others which will require removing the axle.

I did pick up two tubes of Swepco 101 CV grease as I didn't opt for the cheaper LM brand...

I'll advise upon completion....
