Thump/Thud in rear

[RICHARD MEZIC]

In my '91 200 wagon, I hear a thud/thumping noise coming from the passenger
side rear wheel well area when I go over *any* bumps.  I've had the shock
out (and replaced) and it didn't solve the problem (so I put the original
back...).  While things were apart, the ball joint and suspension pieces
were checked - still didn't help.  Any suggestions, BTDTs?

I can't seem to track it down.  Thanks in advance.  You (collectively)
always come up with the right answers...
