    i am having exactly the same problem, I already replaced the wheel bearings and the mechanic told me that my differential is out, that either get a new one or rebuild will fix the problem, he said it will cost between $850.00 to $1000.00 to fix this problem, he also said that the bearings in the differential need to be change, I found this cost extremely expensive, my speed sensor went bad, already replaced but my speedometer still not working, I noticed some like oil leaks from the differential. How expensive will be to fix this problem, what is the risk of me driving long distances? please help.

    Leak found by Jeep dealer during oil change. Seal changed that very day - this Jeep has a lifetime powertrain warranty without any deductible (!!) and also a purchased lifetime bumper to bumper warranty with a $100 deductible. Total cost here: $0.00
    I'll report on any other issues as we go along.

    The vehicle makes a grinding noise when the 4x4 is engaged. No evidence of leakage from the transfer case, so assuming the fluid levels are fine. I took it to JL Automotive in Cream Ridge, NJ & the tech told me that the frontrear differential is bad & needs to be replaced. Also, the front left wheel bearing is bad so that's being replaced. My husband just replaced the front right wheel bearing, CV joint & shaft a couple of weeks ago- the shaft was fused to the joint. Never saw that happen before. At any rate, the total cost for repairs at JL is $2450 not including the $470 I spent on the parts for the front right wheel bearing, shaft & joint.

    The rear differential is starting to leak. What a hassle this Jeep has been, and we have 2 years left of payments. What a ripoff, Never use 4 Your Car Connection in Seneca, Pa 16346

    I am too just going through this now. There was no pre-sign that something was happening, jut out of the blue one day it started to make the whining groaning sound when doing between 10-100 and then just gets louder. I have it into a Jeep shop now, waiting for the prognosis!!
