Chris,
I meant the centre bearing. When it goes, the whole car shakes at
resonant speeds. For a 200TQ it is 35mph, 70, 105 etc.
Here's the relevant to the 200TQ post from my archive:

OK guys,
I stopped by a local M-B dealer and matched up the bearing and the
rubber cap against the M-B parts. Below are the long awaited part
numbers:

Both parts are from a 240D or 300D, chassis # 123:

Bearing: 0039812325
Rubber cap: 1234101081

Enjoy.

Indeed. You have to reuse the Audi holder. Not just the horizontal
slotted for the bolts part (the "ears") but the whole round thingy.
Cut the round steel holder with a hack saw, replace the rubber cap and
the bearing and re-weld the holder closed. You'll wind up with a gap of
about 5mm.

Also, Rod from TPC e-mailed me a few days ago:

I haven't seen the 123 410 10 81A that Rod has suggested but I am pretty
sure that he's correct. In this case $25 plus 10 min of welding seem
like a bargain to me. Especially compared with the ludicrous Audi's idea
of shoving the whole propeller shaft down our throats for $800. Or even
$150 which some aftermarket outfits charge for the support assy.

I later found out that Rod's part worked well.
