Rear differential is locking/clicking on tight turns. (original issue: http://forums.ross-tech.com/showthre...s-haldex-issue)

I'm stuck in the process of removing / checking my haldex clutch
(mediocre reference diagram - http://www.awdwiki.com/images/haldex...tion-1_xxx.jpg)

I have gotten the driveshaft and dampener out of the way
I've removed the flange that attaches to the prop shaft flex disk / guibo. (part # 16 in this diagram)
I've removed the cargo pump (part #17 in the diagram)
I've removed the four #15 bolts holding the assembly together (part #41 in the diagram)
I can get the assembly to slide out a half an inch or so, and it will flex a little more, but something is holding/binding it up and I don't see it.

I see there's a wire coming from the differential to the top of the haldex I'll need to remove, but it's got slack.

I would appreciate a pointer to find replacement o-ring which I've broken. (part #28 on the diagram)
Already found the replacement bushing for the prop shaft which I munged getting out.

Thanks in advance!

At the other end of the prop shaft - I recently had to take out the bevel drive to fix the turbo bracket, so maybe someone will appreciate this as well: http://forums.vwvortex.com/showthrea...al-replacement

I'm still stuck removing this -- any thoughts? Only got about a half an inch separation, will flex and wiggle, but won't come any further.


Can't remove haldex

Any help appreciated... still stuck!

Mister Bally

Does the service manual show a step you may be missing? Such as maybe a Allen head bolt deep inside the center of the shaft that needs to be removed?

Thank you for the thought.

There's no allen head here like there is in the bevel drive.

Unfortunately I haven't found the haldex disassembly in the bentley manual.

I've found fluid changing in the maintenance section (3-61), and pieces related to it in the Rear suspension (42-6)

If someone can offer a chapter or page number, that would be helpful, but it seems like rear-final drive disassembly is out of the scope of the bentley manual.

I feel like the links I have should be sufficient, but the solution still eludes me. I don't want to lower the whole rear subframe to address this.
