There is a horrendous clunk emanating from the rear when shifting and tremendous slack in the entire driveline. All of this after tranny/engine mounts, snubber and rear diff mounts have been replaced, some multiple times. I've r&r'ed the center shaft as well. I'm starting to think there's play in the rear diff between the input shaft and the two axles. I'd love to pop a torsen diff in there but if I can't find one, no big deal. Where can I find a good used rear diff? Thanks!

Same happened to me, the clunck, etc.

See attached photo from this post, you need to change the bushing in the cross member bar part #5.

This bushing has open space above and below, most likely it sheared away and the bolt is hitting the top of the crossmember.

Take a flashlight under the car and take a careful look...<ul><li><a href="https://forums.audiworld.com/s4s6/msgs/179575.phtml">https://forums.audiworld.com/s4s6/msgs/179575.phtml</a</li></ul>

Did your rear growl under tight turns and at 35-55mph? These symptoms make me think its more the diff....

But the clunk was each time I let out the clutch was the bolt for the bushing hitting the crossbar.
