charlies tj clunk noise

01 wrangler 4 cyl.. get a clunk noise in rear end probably in track bar or other support brackets. When one side wheel hits a bump or a road groove I get a clunk noise. Has been this way for months but now seems to be getting worse and even made a noise when brakes were applied. All I could find looking underneath are somewhat loose bushings on link bars. Didn't see any cracked or broken parts. When I push on shocks and other brackets they seem to be tight.
Doesn't make noise when wrangler is rocked from side to side or when I step up and down on bumper. Seems to only make clunk noise when driving. Any ideas on what's going on.

I was stumped for a couple of days with a similar sounding issue. Mine was the stock Muffler had a broken weld at the clamp. It would bang (metal to metal sound) going over a bump. Also if you have a broken exhaust hanger, the cat may bang on the skid going over a bump.

Thanks.
didn't mention that I also pushed on muffler bracket, but it also seemed to be OK. Jeep dealers want $92/hr to look at it. Guess I'll get under and take a closer look at rear end parts.

Ended up jacking the passenger side frame up about 6". Looked at rear end parts but still no sign of broken or cracked parts. When I looked at front end parts would you believe the passenger side sway bar link joint was broken (ball pulled out of socket about 3" after jacking). Could have sworn that clunk was coming from rear but all this time it was the front link socket making the clunk. Put in a new link and clunk is gone...... thank goodness.

Before jacking, I had previously checked both front end links for damage but when pushed by hand they were both tight with no signs of damage. There is a rubber boot over the ball and socket, I guess it covered the broken ball joint.
