Rear inner cv joint removal - Passat B6 V6

[Mawrick 0]

Anyone got any tips on how to get off the inner part of the cv-joint in the rear.

I thought it should be loose as it sits, but it seem very "stuck", but I presume it should be able to split where the gasket sits....?

Any tips/tricks to get it loose without destroying the housing (I kinda think it's due to the rust, but not sure...) (is it normal for it to be this stuck?)

Cast alloy, joined to steel?

Alloy expands at a greater rate than steel, heat should get them expanding at different rates, you could also try a freeze spray or if needed alternate the two.

A light blow with a rubber hammer could also be combined with the above.

 

It could take minutes or days of persuasion with lubricating over night etc.

If the CV is scrap you could also attack it wit a grinder to weaken it into segments and remove a bit at a a time?

Good luck, go steady

Yea thought it might be something like that - thanks for the tips, guess I end up with same "problem" on the other side as well.....ohh well 🙂

If you suspect similar issues the other side slacken the bolts and spray with penetrative oil while you do the side you're currently on, then drop down onto the ground and drive forward and backward to break the rusts hold with no exertion from yourself.

I've done this with wheels stuck to the hub, much easier than a sledgehammer and a block of wood

Already partly disassembled the other side also (changing out most of suspension/drivetrain parts), but that sounds like a good idea 🙂
