I have a 2006 Rubicon with an automatic. I hear clunking coming from underneath when I go over bumps in the road. Accelerating, braking, and turning don't make it clunk...only going over bumps. Help!

If it was me first thing I would do is crawl under there and check all ur suspension. Start grabbing and yanking on stuff to ensure it is bolted tightly and the bolt holes are not worn out. And check ur trans mounts and tie rods. May not be much help but its a start.

check your cat converter and all of the hangers on the exhaust system. sounds like it is loose or your cat has gone bad. a friend of mines jeep did the same thing and i climbed underneath it and the cat had gone bad and the exhaust hanger was loose.

Ever replace the rear sway bar links? If not, liberally spray some lubricant on their joints to see if that quiets things down for awhile.
