Audi A6 C4 differential problem
Hi!
New to forum
I have problem with central bearing on shaft and shaft seal on rear differential
Can't find anywhere in my country new parts, I have searched online but with no luck
For central bearing I have found those JXB replacements, so can anyone tell from experience is it good solution
And is it possible to buy somewhere shaft seal for rear differential (017525400C)
Thanks!

The JXB kit installs and works great. Just make sure the bearing itself is not too worn and noisy. If so you'll have to disassemble the driveshaft to install a new bearing and carrier assembly. There are good videos on YouTube for JXB and replacing the bearing. All seals are available for the rear diff., including pinion and both axle shafts.

Thanks for the answer!
Saw JXB videos, seems pretty good, but some guys said that it can start shaking after installing that carrier
For the seal, once again I have searched, but with no results....

I don't see how it's possible for the driveshaft to shake due to a JXB carrier. In such cases the bearing itself must be too worn or the driveshaft unbalanced. What seal(s) in the rear diff are you looking for? I recently got all of them.
