Clunking in rear....still

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.

Loose bolt on one end of the rear track bar?
Exhaust hitting something?
Loose bolt on shock?

Have a helper rock the Jeep back and forth while you are underneath.

I had the same noise under the same conditions and it ended up being the Trackbar bolt that is attached the trackbar to the axle. Even through the bolt was tight, the trackbar was still banging on the bolt. I fixed it by getting a tighter fitting bolt.

My temporary fix was that I wrapped a layer of duct tape (leaving exposed threads for the nut) on the bolt to take out the slop.

In my case, it was the bushing in one of the swaybar end links. As stated above, rocking the Jeep while underneath it is the best way to track down odd clunks and rattles.

Was able to get someone underneath while I reproduced the noise. Turned out to be a loose axle side trackbar bolt. Thanks for the help all!
