Rubicon express lift

I have a rubicon express 2.5 suspension lift, I noticed if I hit a dip over 20 mph it sounds like the rear end is hitting something. I have looked and can't figure it out there is plenty on clearance and everything looks fine. Any ideas ??

Check to see that all the bolts are tight for the control arms and track bars. If all are tight, I would then check for play is any point there is movement. Might be a walled out bushing. Good luck.

Jeff

I have the RE 5.5 inch lift on mine and had the same issue. The track bar was hitting the gas tank even though everything was properly installed and tight. Had to move the gas tank a bit to the rear for more clearance.

I'm with Jeff. Check the control arms. I had that same problem. They were loose. Now they're not. Problem fixed.

I had a bolt installed incorrectly on my track bar relocation bracket that was digging into the spring. Flipped the bolt around the other way allowing clearance problem solved

Check the control arm bushings. I replaced a set a year ago and just started tearing them again. Im going to live with it for a while.

I ended up fixing the problem, rear driver side spring shifted a little out of place.
