Rear rattle and clunking
After two days of fooling around with rear shocks and upper mounts I found the noise, and it was an easy fix. On my 2000 SLE the noises were terrible enough that I was not going to drive it ever again untill I found the noise. Jack it up and look at the body mounts on the rear subframe, just under the rear of the rear doors. That is the pronlem. Pry on it with a big screwdriver, and if it creaks, that is it.Run out the big bolts, put a big thick flat washer on it tighten the hell out of it , and you are done. Just like magic, perfectly quiet..........FINALLY!
