So...noisy Wj on bumps. Cant find the culprit. My 4.7 Jeep makes hella racket when going up and down the driveway and I don't quite know where it's coming from. Mind you, my driveway is like a logging road but it's a Jeep... does it on the road as well when you hit bumps. I've had it on the lift and can't seem to isolate the reason for it. Maybe that's due to the suspension completely hanging with no weight on it. Idk. Right after getting it I had to replace both rear lower control arms. But other than that the suspension seems fine. I've grown to know these Jeeps quite well, as I've had four of them and I've worked on more at the shop, seems to be a issue a few others I've worked on have had as well. Also at times get the death wobble. Not good. My 4.0 I haven't gotten on the road yet due to the fact that I have to repair the 4.7 and feed it gas all the time Lol. Its not a bad Jeep at all, and really hasn't needed much, just want it right as that's the daily right now and my pregnant fiance drives it too. Any help would be appreciated.


Brown and blue are mine, silver one is my customers

 

Look at the ball socket on the upper control arm in the rear. If you've already replaced the lowers, chances are the upper is at fault.
