Rear end clunk (suspension related), forward to reverse.

[94-302-vert]

My rear end has a clunk in the suspension. If I back up and jam the brakes then when I go to pull forward it sounds like the rear end moves as I get a noticable clunk. It very seldom does it when actually driving unless I do a hrad stop followed by a spirited launch.

I have already checked all of the bolts to make sure they are tight and they seem to be. It will do this every time the car has been sitting for any length of time. Is this jus tsomething as easy as not enough greese on the poly bushings, or does it sound like something more severe, like a bad torque box (they "look" fine, not sure what to look for though)...

Thoughts?

take a look at your control arm bushings. check to see if they look cracked or dry rotted. That is very well a possibility.

nevermind I just noted in your sig. poly control arm bushings

It could just be they need a little grease. Check em out

Check your u-joints and the driveshaft to pinion flange bolts. Check for excess play and/or broken u-joints.
