Golf V R32 :: Loud Clunking Noise In Rear Happens Over Bumps

There is a clunking noise coming from the rear of the car. Not a metal on metal sound. Sounds like its more on the passengers side. I replaced the swaybar linkage ends since they were a little loose and thought it was that. Nope...I have H&R coilovers, they are about 5 years old. Can't imagine they be shot this soon. Had someone drive my car while i was behind the R and the rear wheels aren't dancing at all, a common sign of a blown shock. Push down on the car, shocks still respond like they did from day one. I've put the car up on a lift, both sitting and wheels dangling. With the wheels dangling, I grabbed onto the shocks to see if there was any play in the upper shock mounts, solid. Looked under the whole car for loose plastic covers. Can not see anything loose. I made sure everything inside the hatch, including the battery is sitting snug.

The clunk happens over bumps, with or without the brakes on and is loud enough that if the radio is on, it can still be heard.
