these are the parts were talking about, not from rs6, but similar stuff...
looking at it i dont think its the flangeshaft itself, has to be a bearing or shim...

Can you pull it out to inspect? You've already got the drive shaft off haven't you?

well, we did it outside in front of the garage, cos theres more space. put it together cos of time limit. but will have another go inside the garage...
We couldnt check oillevel cos the front was on jackstands...

Wander if theres any oil in with this amount of play, think the outer seal isnt working cos of the play...
If its a bearing, its an engine/gearbox out job, as elsawin mentions.. we couldnt see a way to get the part of in which the flangeaxle is in. theres a piece of the exhaust running in front of it, also a piece of the frame/subframe (dont know how its called)

Ive never heard someone with the same trouble and without taking the engine out...
So, not really sure what to do next... :cry:Just keep driving with this clunking and possible causing more damage, or....

...but Elsawin says to remove the engine for O2's as well :o

From Elsawin:

- Remove front exhaust pipe (left-side) and front exhaust pipe (right-side) with flexible element → Engine, mechanics; Rep. Gr.26. – Remove gearbox support (right-side)

Removing and installing front exhaust pipe (right-side) – Remove engine → Chapter.

Possible, but not easy. It's a pain to have to remove the turbo. Better pray the bolts aren't seized...

i think by just loosen the turbo will have prob enough space to get the diffcase out...

...i managed to get the flange axle out and noticed the needlebearing can move in-and out for about 1-2 mm. Dont know if thats normal.
The part that covers the needlebearings hasnt got play. So i think the diff itself neither.
Was surprised there was oil coming out after all those kms leaking.

But i dont understand why i can move the flange in- and oud for about 1,5-2mm, but when i just insert the bold without the flange theres no play at all.

Excellent job, Mav! What did you have to do to get enough room to remove the flange? (Told ya it could be done.. .;) )

Not sure what your question is?
