I just installed my RUSTS 2" lift. All went well w/ no problems.Prior to installing lift i had a noise in the rear when i would hit bumps. It sounded like a hollow knock ,that seemed like something was hitting the floor pan in rear. Now w/ lift it sounds louder. The only thing that seems loose in the rear is my exaust hanger by swaybar and muffler causing up ward movement. COULD this be my problem?

 

yes it could, see if you can tighten it up

 

could be...did u replace the shocks? that could be it also.

 

Shocks were replaced and are tight. I told the guy who installed the muffler and tail pie to put in new hangers. It just seems like the one in front of muffler has some movement.

 

I would check that and look to make sure your tail pipe is not hitting your frame rail. I had that problem

 

How about the bushings in the spring eye? Are they a typical wear issue on these Jeeps?
