I've had this nasty thump on the right hand side of the rear suspension. I looked it over really well, nothing is cracket or otherwise worn out. I know the shocks are suspect, but I've never heard a bad shock make this noise.
Is there any chance that the upper shock mount rubbers could be sacked out?

The only way I can describe the noise is as though I had an empty wooden box in the trunk and it was bouncing around. Now, I DO have a wooden box in the trunk, but I removed it and the noise remains. Tied down or otherwise removed everything in my car that could make a noise and it's still there.
Also, it's a "vertical" type of noise. I swerved the car hard in a parking lot and the noise wasn't there, but when I drove in a straight line over a nice speed bump ( at any speed mind you) at about 30Kmh it's a distinct banging sound from the right rear corner. sounds like the axle is bouncing. but the snubber and the droop catch are not worn shiny as with regular top/bottoming out.
