Well, I can sympathize with you. My 06 EX has an intermittent squeak from the rear. Usually after being unloaded. Usually squeaks are bushings and clunks are bad joints. I haven't been able to isolate the squeak to a single bushing (or even one side for that matter). I just decided to ignore it. Not the best idea, but with 214k miles -it could be worse. I have not noticed any difference in handling or ride since the squeak developed. I have considered slathering all the bushings in the rear with silicon grease.
