Check to make sure you still have all of your lug nuts, check your shocks. Does it do it at any speed just as long as you turn right? Does it do it when your backing up and turning right as well??

check your track bar bolts. This is usually the cause for mine. Check the axle side as it is the most likely to back out a little.

yes i need to put some thread locker on there and want bump up to a grade 8 instead of the metric 8.8. And often, no, but once or twice a year, then yea. But it typically is brought on by the cold for some weird reason.

in order to tighten those bolts down, would you have to drop the skidplate? im in school right now and cant go outside to look.

I checked torque on all bolts check good. I was wondering if common that control arm bushings are worn. I feel the thump under my left foot.

I have a thump thump sound too... mine is the upper track bar "ball joint". It is worn and has play in it. I had my wife slowly turn the wheel back and forth and not only could I hear it, I was able to feel it as well.

That is my exact symptom. I dont want to jack your thread, have you noticed it with a good bump as well?? I was wheeling yesterday and everytime I came out of a good mud hole it would thump.

Does yours do it when you are sitting still?? If my jeep is idling at a stop I can turn the steering full lock both directions without any binding/popping/thumping, it only happens at slow speed or mud holes??
