Rear Suspension Thunk, Clunk- Different...

[John2]

i've got a '92 w/ 190k. just converted from air suspension to Arnott struts and did the work myself. There was plenty of noise from suspension before, but now that all is fixed (front upper and lower ball joints, control arms, new struts, etc..), there is a thunk or clunk from the rear - easily reproducible. it's caused by a side to side motion of the car. car hear at any speed when turning right to left or vice versa. or by pushing/pulling on rear tire- one can feel the clunk in the wheel. it's a simple single thunk as it moves right, then another as it moves back left. i've read up on the rear carrier bushings, and those symptoms don't seem to fit this issue. yes, the tire/wheel is tight- just checked. i'm also sure the top strut mount bolts are tight- plus the noise is lower, not near the rear deck. ideas/help, please?

Replace the two rear sway bar bushings. They wear out over time and cause the noise. Probably a $15/15min fix.
