HELP metal popping sound while turning left or right only when accelerating

i have a 02 tj sport with 44re and have this popping sound comes from the rear and i can feel the rearend shift when it pops and hear metal grinding when it pops. i have the rough country 6in lift with a sye and cv just got put in a couple months ago and im running 33x12.50 still. the rear track bar that is the stock one with the rough country bracket is leaving marks on gas tank skid plate but its not loose at all i cant even move it with a pry bar when i try. i know i have the wrong bolt in the track bar mount to the rearend but i don't think it would cause it to twist in the bushing. but anyways yesterday just going down the highway my jeep starts viberating when i was doing 60mph and i could barely control it going from right to left so much in the rear. i checked everything out and it looked the same as before so i rolled away slowly and no vibes until i hit 50mph and i kept pulling over cause the vibes wouldn't stop until i slowed down to 10mph and then i kept repeating this till i got home and everything is still tight so i trying to find out if anyone else has this problem and i have a rear adjustable track bar and new bracket on order still hasn't came yet im in hawaii

DOOD I had the same problem... I thought it was suspension or traction related... ITS NOT ... Pop open your rear differential cover, then check your Spider gears for broken teeeth. If you dont see any, check the bottom of the inside of your case and you may find some teeth, hurry and do this before anymore break. Im doing it now as we speak. Not expensive fix at all. If you want to see what it looks like, do a search on youtube and youll find nice vids on people pulling tons of broken teeth outta the differential.

Could be the limited slip. Chang your diff fluids. Be sure to add the friction modifier.

Patriot Blue 2001 TJ
Everything I need to fix on the heep: ABS indicator, speed 4 on the blower fan, torn softop over driver's head, both seat release/tilt cables, missing center cap on spare, broken under hood light, wire up the CB, wiring problem with the reverse lights, broken bottle jack, leaky front and rear pinion seals, loose trackbar relocation bracket, torn drivers seat on the side, broken center console lock, lost nuts for door hinges, squeaking centering ball, loose parking brake cable, oil change and rotate the tires.

Most synthetic gear oils like Valvoline make already have it mixed in. Just go to Pep Boys or any local parts store and you should be able to pick it up for 3 - 6 bucks

You have to do periodic inspections of the pig, not only to change out oil, but to avoid carrier breaks by "nipping it in the bud" so to speak checking on the spiders. Don't ask

I went through the same thing. What was kewl about Jeep TJs is they had a 7/70 warrantee on the transmition which includes the differential. Look into it. It could save you a few hundred dollars. All mine cost was 100 dollars and the dealership let me drive a loaner car in the mean time no extra charge.
