I need some help. Under heavy acceleration or while turning my jeep makes a clunking noise from below he drivers seat. It won't happen very offer at first but the more you drive the more it happens. Only happens in gear and I have no idea where to start.

 

drive shaft ujoints? Time to crawl under there and start checking for slop.

 

If by slop you mean I can shake either drive shaft. I tried and I can't. But thanks for replying this is my second post and your the first person

 

But I checked again and the rear driveshaft does have a bit of wiggle going into the transfercase

 

Does it have any slop in the steering, as in any floating or wandering issues? If so (and even if not) I would also check out control arm bushings.

 

No steering issues. And if it helps bumps don't really effect the sound. I'll take pics of the bushings in the morning for here.

 

Check u-joints, and look for slop on the output shaft of the T-Case. I just replaced my T-Case and it cured my problem

 

I heard a clunking noise as well seemed to come from the same place sounded rotational thought it was ujoints, put the cherokee on a lift and when i turned the front driveshaft the tires didn't turn. Pretty sure my ring and pinion and/or spider gears are shot

 

just removed my front driveshaft, with the wheels on the ground i can rotate the yoke on the pinion by hand. must be pretty messed up in my diff hope you have better luck

 

Pop the cover take pics!

 

Looked under today. All my bushings look bad but not horrid. And so do my mounts. My u joints have no play but my driveshaft does at the t case. I could start replacing away and I probably should but I really need to save cash and hit the nail on the head the first time.
