Front/Rear Differential Pinion Seal/Transfer Case Leaks are Common on Jeep Liberty

Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Low fluid level in the differential or transfer case can result in bearing failure. Damaged bearings commonly cause a whine or growl type noise.

2003 Jeep Liberty - Automatic Transmission 12,700 mi,
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.

When driving at any speed and at any time a noise starts. It's like it is coming from one of the wheels on the passenger side. When the car is stopped the noise that sounds like cards clicking on a bicycle tire stops so I can't figure out what it is. It can get so loud that you think the tire is going to fall off, so you pull over to look but can't find anything wrong. When you start the car the next day, there is no noise, sometimes it won't happen again for a week or more. Need help solving this problem.

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!!

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.
