Recently my 2005 Limited started to make a whining sounding similar to "rrrrrrrrrrr" best as I can describe. At first I thought tire wear as the Jeep has 19K on the clock. Anyhow, I took it to the dealer I purchased it from and sure enough, they found that bearing(s) in the rear axle are bad and have ordered replacements. The dealer hasn't run across the problem before. My post is just an FYI.

Probably just a fluke. I'd see if they're going to extend the warranty at all on the rest of the axle, in case you run into any other problems with it from the premature bearing failure.

Sister in-law had her rear bearings go and it was making a "rrrrrrrrr" and birdie sound. Replaced bearings and good to go. Of course she drives a Chevy Truck. Regardless I think your case is just a fluke like Tim said. I have not heard anything regarding bad bearings on the KJ's until now.
In another 19K report back to us if any noises have returned

My brother had to get his rear bearings replaced in his cherokee when it has low miles on it. Im thinking around 18k but idk.
It has the same 8.25 axle and hes not had any trouble out of it and he is at 67k now.

Bearings
OK, just another thought. About 3k miles before the "bearing" issue began, I had the oil changed like I usually do at the dealer. Since it was time for differential fluid changes, I had that also done. Now my question is, if they removed the oil from the rear diff but forgot to fill, how long would it take before the pinion gears begin to "complain"? I drive a fair amount of interstate 75mph highway and would imagine driving at that speed about 1/2 the 3k between oil changes, they would have failed long before now.
Anyone with knowledge on the subject?

With no gear oil in the differential, it would have locked up pretty quick. It's possibile they didn't fill it back up all the way, but if it had nothing in at all, you'd figure out real soon.

about 10 miles before it started making noises.

just curios,
When you say the "axel bearing" do you really mean it was the axel bearing, or was it the diff bearing?
The reason I ask is because I have an 02 KJ with 200,000 km on it. The back end has started making a "rrrrrrrrrrrr" noise. I pulled the back diff cover off to have a look at the gears. I suspected maybe someone had not put enough lube in or something. The gears looks almost brand new. Which makes me wonder if the problem has been here for a while and the precious owner had been chasing a problem allready?
Anyway, I have decided its a bearing problem. Mostly because when I first get in and drive, there is no noise at all. Then after a few blocks it starts to make noise, and then 10 minutes of driving and the noise gets the most worse.
I was looking through the FSM and figured it would be the "diff bearing". My only reason for thinking this is because it states that the axel bearings would make more noise under load, by turning hard onto one wheel or the other. Since my noise comes on at about 60 km/h (45 mph I think) and is the loudest then, but is still there (quieter though) at 120 km/h in a straight line it says it should be the diff bearing.
So I am curious to know if your situation was the same, and they just said "axle bearing", but really changed the diff bearing. Or if it really was the axle bearing.
Anyone with some insight on this? Otherwise I may just replace them both while I am there anyway. I would much rather not though.
