Posted this in the general forum and thought I'd put it here.

I know there is a tsb on the rear diff. but today got in the car and heard a clunking sound. I did not start it, got out of the car and pushed it back and forth in the garage, each time I did this there was a loud clunking sound. Does anyone have any thoughts what this might be, might it be related to the tsb, again the car was not even started yet. When I say I pushed it I just mean car in park and just shook it back and forth.

 

My initial guess would be the swaybar endlinks.

I had a front one go bad and replaced them. I also had a rear bolt come out from the rear swaybar bracket on the car (you can see this from the rear if you look under the car...there will be a bracket on the left and the right with 1 nut and 1 bolt each. Check to make sure they are there, lol)

 

you need to isolate the sound and start looking around the area for something loose.
there are quite a few things on the suspension could make that noise if they were loose or broken

 

Have you checked your rear axel nuts?
