Rear end noises...

I'll try to be as succinct as possible, but this is a little drawn out.

3-weeks ago, I went from stock '02 TJ with 30/9.50's with a little DW at 50-60MPH, that I attributed to trail alignment after breaking my tie rod, but otherwise all was good.

Several months back I got used 4" Pro Comp springs and shocks from a buddy of mine. Then I got a smokin' deal on a set of 33/12.50 mud tires on some 15X10's. So in went the springs and shocks and on went the wheels and tires and OMG what a mess! After a good driveway alignment, most of the DW is gone, but it comes and goes around 40mph now.

Background over, I noticed pulling out of my neighborhood, uphill to the right, I was hearing 1-3 clunks when letting out the clutch, coming from the right rear. It would occasionally happen other places around town, but always when turning right. It seemed to go away, so I dismissed it. Then a few evenings ago, after a nice drive, I turned down my street, turned down the stereo, and heard a new noise. For lack of a better description, it sounded similar to peeling a sticker off of something. It repeated as though it was coming from a specific place on something rotating, tire, wheel, drum, axle, etc. Being late I didn't look too hard, but couldn't find anything looking out of the ordinary. Then this morning, it seems the sound has changed to a pop from the right rear, at the same interval as the previous sound. Thoughts? D35 dying?

Pull the right drum and see if everything is where it should be. If ok then pull the diff cover and have a look there.

so you got springs and shocks, but did you get a rear track bar bracket? Or longer sway bars? Or anything else other than just the coils and shocks? Could contribute to the problem, but I can't be sure.

I get that (most likely the) same popping noise from my rear axle. I plan on putting in new shafts assuming it might be the bearings...

Right you are, the rear is kicked over to the right about 1"-1.5" with the stock track bar and location. I'll have a look, I may have to move that adjustable track bar to the top of the mod list.

So you are both getting similar sounds out of D44's? In a way you are giving me hope. Hope that it's not the D35 dying!

Saturday, I guess I'll jack up the rear and play spin the tires! Start at the lug nuts and work my way inboard. I'll let you know what, if anything I find.

Feel free to add further suggestions. Thanks all!

Adj. track bars are always legit. Should get the bracket though, which raises the mounting point on the axle end to accomodate the 4" lift. I think a good one is only like $50

I'll leave the popping and sway bar stuff to the veterans and this is going to sound stupid, but your sticker noise at the same spot on rotation is most likely tar on your tire. My wife came home frantic not to long ago that something was wrong. Same noise, same description. She had went threw a freshly paved road, it was very hot out, and tar got on the rear tire. Tough to see on a black tire but kinda funny when I showed her.

Nothing to report. I ran a couple of errands Saturday morning, and not a sound from the rear of my Jeep. Friday night, sticky, squeak, bonk...Saturday, Sunday, and Today, nada. 100 miles and not a sound. Typical of my cars, they have all been possessed!

Thanks for the suggestions, and I'm sorry I don't have any answers to pass along.

man... my rear axle snapped and stopped working! It will only go in 4LO. When Idling in drive in RWD the rear axle grinds and pops and snaps, but does not move, even with the throttle. I wish I knew what was going on...
