I did the adjustment today. Seemed to help out a lot. I am still have a clunk in the rear end area. I have yet to have this car on a lift, I have never even really looked under it. This Saturday I will get it on a lift to replace a tie rod.
I am going to look at the flex disk's and halfshafts. To me those two things sound like the culprit. Kinda sounds like an old American car that needs U-joints real bad.
Sound like a good plan of attack?
