I have had a clunk in the rear (sounds like passenger side) that I have been chasing for months. I have replaced the end links and bushings on the sway bar, which did get rid of some noise, but not this particular one. If I stand on the passenger side of the rear bumper and shake it side to side, more so than up and down, I can replicate the noise. I can only hear the clunk when going very slow over bumps, and it is one clunk when hitting the bump. When driving normal speeds I don't hear it at all. It doesn't need to be a jarring bump to produce the noise. It does it with any slight rocking side to side; like going over a speed bump a little crooked would cause it. I have grabbed and pulled everything I can think of and checked bolts and cannot find out whats causing it. I can also get a similar noise, again when coasting very slow, if I move the steering wheel back and forth about 6-8 inches, enough to make the body roll but not swerve.. While doing that, the clunk will happen at each change of direction up until the Jeep comes to a stop. As soon as the Jeep is stopped, the noise stops. I know I'm all over the place here, but this is driving me nuts! Any help on other things to check would be greatly appreciated.
