Differential Unit problems of the 2000 Dodge Durango

The vehicle started making a loud humming noise in the rear end coming from the rear differential at around 30 mph, and gets loud while increasing speed. Dealership wants $1200 just to install a new one, price does not reflect the $2500 rear differential. Widespread problem, and no action I being taken. Obviously a flaw on there end, the car has not been beat and in pristine condition. Called about this problem, only for them to tell me the warranty expired 10 years ago, obviously but everyone's warranty expired and are helpless because of a problem arose by them.

At approximately 55k (5/03) miles I had to spend $1662 for work on my Dodge Durango's differential. It has been my experience that these types of problems don't come up until way over 100k+ miles. Then 11/03 it was mandatory that I replace all 4 ball joints. This also doesn't seem right since the car only had approximately 65k miles on it at that time. You would think when you take your auto to the dealer for all its scheduled maintenance and having spent $35k on it new, one wouldn't be having these sorts of expensive problems.

I had a lot of chattering and grinding noises in both the front and rear differential. The dealer checked the problem and found out that the differential fluid needed to be changed due to the viscosity being weak and recommended that it be changed and additive be done. Upon finding this out they also said that this fluid would have to be changed every 30,000 miles. My cost for this problem was $400. 00. It was not specified in the owner's manual that this had to be done at all.

The vehicle is having a bearing failure in the differential which can cause the unit to seize and I have taken the vehicle to the dealer I purchased it from 4 times and each time I get a different story on what they feel or think the problem is.

Vehicle has severe whining noise from rear diffrential. Also has grinding/clicking noise to date, rear differential ring and pinion has been replaced (not fixed); complete rear end assembly installed 05/01/00 (not fixed), dealer contacted me and told me they would "rebuild the new assembly to try to correct the problem, and would not give me the vehicle back until it has been corrected. " this is 3 attempts at the same problem, I. E. , new gear set; new rear end assembly; currently rebuilding the new rear end assembly (without ever having returned vehicle to me with new rear end installed).

While driving vehicle would make funny noises in the front differential. Also, would pull to the right if steering wheel was let go & brakes not applied. Took vehicle to dealership & informed consumer it was a caster adjustment & it was already done. However, problem still existed. Took to dealership in arizona, and informed consumer that it was a design flaw, and manufacturer knew about ak.

While deaccelerating noticed vehicle was making a howling noise. Dealer has changed differential ring and pinion gear. Please provide further information.
