Need help with rear end clunk
Well, I've had a clunk sound for about a year now. It really only started after my lift,etc was installed. Took it back to my suspsension guy/buddy twice and he checked and retorqued everything and the clunk is still there. I checked and torqued everything myself,sway bar&links,track bar,brackets,etc,everything I can think of and marked it all with white paint pen.
To make a long story short, even had the rear diff carrier/locker replaced which was not the problem cause the clunk is still there. The clunk sounds like it's coming from the rear end.
It's not the jack or door latches which I've seen in other posts and it only happens when either making a quick left or right turn or driving over rutted out or bumpy uneven terrain.
The control arm bushings look ok but don't know how they look on the inside. I've just been ignoring it and turning the radio on but it's just buggin me not knowing what it is.
Anybody got any ideas?
Thanks

The way I found it was by pushing the jeep up at the bumper (don't do the normal shock checkup procedure of pushing down on the corner, instead pull or push upwards), and I was able to see how the bushing had some play.
Good luck and let us know

I had the same problem and it turn out to be my left shock bottom bushing, the metal part instead of being round was oval, it sounded just as you describe it, when going trough uneven roads and when turning a quick left (since doing this will rise your left side and pull your left shock).

If they are new I don't think that's the problem then, but might as well and check, by the way those are the same I got to replace the stock damaged ones.

X2. This is what was causing my clunk in the rear. After the lift, the rear coils bowed outward, hitting the track bar. Because of the change in lift height, the angle of the axle spring perch rotated towards the back. You can put 10 degree spring wedges that sit between the spring perch and the springs to correct the angle and straighten the coil. I picked up a pair of ones for about $30 and it fixed my issue. There are weld-ons and bolt-ons but these worked fine and was the cheapest.

I was able to check a few things today. Pushed up on the rear bumper and found no play nor heard any sounds of movement with the shocks. The AEV kit came with a geometry corrected rear track bar tower and new track bar which I assume would take the spring hitting the track bar into account.
Took a few pics. The springs are bowed and driver's side spring is very close to the tracbar tower bolt,probably within 1/2" but there are no signs of rubbing on either side of the track bar or sway bar end links. How bad is it to keep driving with bowed springs and should this be fixed?
Still stumped. Any other ideas?

its hard to see in the pic, but on the driver's side, how close is the coil to the inside of the track bar relocation bracket? looks like it is almost touching.
edit: never mind, reread your post.
