I'm driving a well used 200q20v sedan.  Driver's side rear bushings on the
front of the trap. arm for the rear suspension bangs against the body; same
issue you've got.  Seems that the cars from the pot-hole ridden parts of the
country can wear out these bushings.

My original 200q20v was going to be a donor for this part, since the bushings
and bracket looked fine.  Pulled it off to find that the 10.9 grade 22 mm
head bolt was stripped, entirely.  Consensus is that someone prior to my
ownership (say 120k miles earlier) replaced the bushings/mount, and
cross-threaded it with an airgun on installation.  I'd been having a big hand
ling issue with the back end of the car...postmortem not been done quite yet.

Bushings are available separately (got mine through Scott Mockry  The later cars (S4/6) use a larger bushing and
mount; some of the late 200q20v might also use this (the family album is
