Thunk

[david jankowski]

Hello,

    New to list, so just have a quick question for everyone.  The car is
a 1986 4000cs quattro.  Problem that I am having is a persistent off
throttle driveline thunk.  Have replaced trans. mounts, front engine
limiter, front subframe mounts, rear subframe mounts, all control arm
bushings, all strut mounts, rear diff mounts, and rear diff with known
good used diif.  All axles do not appear to have any play, center
bearing does not appear to have much play, and all tie-rods appear
good.  At this point I am starting to be running out of options, but I
could be wrong.  Thunk feels to be from rear, but can't say with
certainty.  Any suggestions would be much appreciated.

Thanks
