Twice my jeep steering /travel got loose while going down the highway having me fight the wheel the whole time. Had a mechanic look at it and when he turned the steering wheel there was lots of movement underneath all the way to the rear wheels. Both times letting the jeep sit overnight all goes to normal! jeep dealer can't troubleshoot because it fixes itself before I get it there. Also the travel is so bad the esc light comes on and shuts off the cruise. Not fun driving for 8 hrs from Mass. to Pa. it is a stock Sahara with trailering package/tsc. Have wheels ,tires and lift kit but don't won't to install until this is figured out. To me it sounds like some kind of sensor because it fixes itself. Any help out there?
