CV drive shafts identification & boot replacement

PostPost by: gjz30075 » Tue Nov 21, 2023 8:30 pm

I use the Schnorr washers under the Allen head bolts. They're dished and serrated. I understand
this is what the Porsche guys use. I also safety wire the allen head bolts together. No loctite.

Alan & Andy
Where did you get the shafts from? Mine are same and I'm trying to get the CV boots with the metal ring attached? I cannot remember where I got mine.
The inside nuts on my shafts had backed out a few threads so good call on the Loctite.
Thanks
James

Looking at this again, I think I agree. The VW CV's normally have a reduced diameter section that these don't have. I think that is on the none boot fitting side of the joint. If the bolt are not triple squares but hex or torx that would also point to not being VW joints.

For replacing them you probably looking for a ford place that supplies parts for Merkur X4TI in the US (aka a Ford Seirra). Or you can compare the CV measurements and see if one of the VW boots might fit as they are easily available in the US.

Hi all,
I don`t know if this is helpful, but I bought my CV shafts from Kelvedon and the packaging used boxes for Shaftec U/joints. Unfortunately there is no type or model number visible. I have also bought replacement boots from them.

These guys have a huge range of boots etc. It might be difficult to I/D the correct one however.

Thanks Ian ... called them! Pretty rude response from their marketing guy! He couldn't get me off the phone quick enough with a promise of a return call... still waiting!
Anyho ;-) I found a part number and ordered them from Amazon...
Be here on 28th... hope they are correct

Happy turkey day!

Hi. I spent some time trying to locate boots back in July; I made a thread back then. I bought replacements from ebay for VW T2. I used loctite 272 on the bolts. All went back together nicely. I have done one side and will attempt the other side at some point but it isn't broke yet haha.

Sean,
Sorry to be a bit heavy but.
Could you tell me if you used Loctite Activator with the 272 please. For threads into Alloy Activator should be used as far as i know. From my days working as QC Engineer in Aerospace Industry.
Cheers

Hi Alan. I'll look into loctite activator. I just used loctite. The car has been in the garage since.

Hi
I have followed this post with interest as I bought a set of CVs from Mick Miller in 2002. They have never been a problem and are still in use today, I notice that mine are different to the ones shown in the posts in that they use all Hex bolts through the spiders with a serrated washer. the boot and cv are fitted with socket cap bolts and spring washers without Loctite and none have ever come loose.
In just over 20 years they have never been anything to worry about. The car is a plus two if that makes any difference as the shaft is longer.
As for split boots this is most likely from external damage.

I watch with interest
