[s-cars] Rear suspension ?strut bearing?

The part number you got from Rod is a bearing for the front struts.  It's
not used in the rear.  The part that you list for the rear, 441 512 331, is
the correct part number as best I can tell, but I don't have a US version of
ETKA loaded so I can't confirm it.  It is possible that the US cars have a
variation of that so if you really wanted to change it you'll have to stop
by your local dealer and get the number.  In either case, it is not a
"bearing" in the traditional sense with ball bearings since there is no
rotation going on there.  It is just a big rubber mount with a bushing in
the middle.  I wouldn't sweat it as it's not the source of your noise.  The
squeaking you're getting is from the upper control arm.  They're about $130.
Mine's doing the same thing.  Though it seems to go away for a while and
then come back.
