Rear Diff question
Ok, so I recently went from being a car guy to getting into the whole 4wheeling aspect of motorsports, so I'm not retarded when it comes to vehicles, just not completely used to Jeeps yet. That being said, here is my problem:
I have a 99 xj, lifted about 4.5" on 31's with a stock rear end. Recently upon acceleration from a dead stop I am hearing a metalic popping noise coming from the rear differential. If I am making a turn while accelerating its not as loud, but it kinda makes a tinging sound. Anyone have any idea what this could be? My immediate thoughts are pinion bearing. Any other ideas?

Start by looking to see if they are deformed or any cracks in the caps also check to make sure the lobes don't look they they are deformed the joint could have play in it also

If both are in bad shape you can usually grab it and twist it with your hands. You'd be able to see or hear play in the joints. It might just be the rear though, so if it looks really beat and rusty I would pull the driveshaft. If any of the caps are seized or grind when you move them it needs to be replaced.

Do you have a sye?
Check the centering ball on your yoke. Mine had a "pop" I thought was ujoints but they wouldn't budge. Didn't find it till it totally broke.
