Just about every bump I hit that is any more than a sealed crack in the concrete I get this annoying rattle/clunk. I can not seem to find this rattle anywhere! I have been looking for awhile now and even had the jeep up on a lift and still have no luck. The noise sounds to me like it is coming from the rear but it is hard to tell. I also can kid of feel it in front of my driver seat in the floor, but again im unsure if you can feel it throughout the whole vehicle or not. Also all noise goes away with the light application of the brakes. It doesn't have to be much brake pressure at all. Jeep is still on factory shocks if you guys were wondering.

There's a ball joint on top of the rear differential. Check that first. If that's tight look at your shock bolts. Those are the two main places on a WJ.

Its a WJ thing only. On mine I changed out the shocks then the noise started. I first replaced the ball joint no help. Next I disassembled the whole
Control arm and replaced everything. Still no help. I checked the shock bolts and noticed a shoulder worn on one. I got metric bolts and replaced them. Finally! Peace and quiet going down the road. Try it you might like it!

I've had an rattle, noise since I bought mine 4 years ago. Sounds like a snapple bottle in under the back seat or something. It is't always there, but ofter enough that it drives me f'ing nuts. I've taken it to a few different mechs, including a transmission specialist and none could tell me what it was.

I have the same rattle, from what appears to be the left rear brake. It goes away when braking. I'm curious guys, how could a ball joint rattle or a lower control arm rattle be affected by even light pressure on the brake? I'm going to pull my left brake apart this weekend and see if it's the pad rattling. I'm just curious if I'm being a noob and not understanding some sort of pressure the ball joint or the control arm may be under when even slight pressure is applied to the brake. :dunno:
