Hey there folks, after getting my first XJ a couple weeks ago we picked up a 99' TJ for the wife. It has a teralfex 4" system already installed but I have noticed the strangest thing... When you accelerate the back end rides up and to the right, and when you let off the throttle it settles back down. It's bad enough I have been letting the wife drive my XJ while I drive and diagnose her TJ. But I'm stumped. Any ideas? It seems like axle wrap or maybe a track bar that is out of whack.
