Been off line for a few days, but I just wanted to express my thanks to everyone that provided much needed insight, help, and suggestions to solving my problem. After reading all the responses, inspite of everything "looking" ok, I am preparing to drop out the entire rear suspension, replace the RR trailing arm which is suspect, replace all bushings (sub frame, trailing arm, and diff mount), and replace the rear shocks if they look the least bit worn.

I suppose I should grease the rear wheelbearings while I'm at it. I still a little foggy as to whether I should use eccentric bushings or just go with stock. Since I'm going to replace the trailing arm, I guess stock should be just fine?

This forum is definitely a real plus.
