I had a clunking/squeaking sound coming from the pass side rear of my car as well. Thought it was the shocks/no, thought it was the sway bar/no, thought it was the control arm bushings/no, even thought it was some unk interior piece/no. After all this thinking found out that it was the rear spring isolators. The factory ones are crap according to people I know and once I checked those found them to be deteriorated and the springs were bangin around back there. A rather lengthy explanation, but that was my problem, them sounds/squeaks are so irritating. good luck!...
