Couple days ago I noticed when takeing sharp low speed tuns to the right, under some body roll there is a very light clunk from the rear driver side of the car.

Hard to tell where it is comming from, but The upper control arm ball joint looks like it could be a suspect, due to its design? Has anyone had a similar problem, or any other rear suspension clunk issues, and what was the cause?

 

Several possibilities; sway bar bushings could be worn, worn/broken shock mount, or worn ball joint. Sway bar bushings are easiest fix, followed by shock mount, and finally the ball joints are the most difficult to replace.

good luck
