Failure Date: 02/15/2014

While off road very far into the desert of arizona I was traveling with my permanently disabled wife. We were on desert trails and the trail lead into a soft silt type dry wash. When I tried to put this Jeep into 4x4 low range a message popped up in the interment cluster that said "service 4 wheel drive". The Jeep would not shift to 4x4 low range and lock the differential and drive through the dry wash to safety. This problem is directly related to the "safety recall n23 / NHTSA 13v-175 reprogram final drive controller module" that a jep sevice center had preformed. The final drive controller module (fdcm) (n23 / NHTSA 13v-175) re-programming that I had performed at a Jeep service center caused this potentially fatal problem that could have left my wife dead. If we hadn't had water to drink or if it would have started to rain we(she) could have drowned in the wash while being trapped in the Jeep, because I could not place the Jeep in 4x4 low range and lock the differential to drive the Jeep out of a potentially fatal situation.

This is a common problem that is found all over the Jeep forums and internet, these Jeeps are known for the rear differentials failing and having to be replaced before the differentials fall apart and could cause a major accident, the differential will begin to fail by making a loud whine gear noise from the differential. This vehicle has never been off road and there is no reason for the entire differential to be destroyed like this, this is horrible quality and should be replaced by Chrysler. This is not a user error, but a part manufacturing error or design error. This being so common it should be a recall. A woman and child in the car driven daily to school should not fail like this jeopardizing both lives.

Car made a whining noise at 35-45 m. P. H. Bought new tires and alignment. It turned out to be the rear differential. It was rebuilt for $1200. One week later it made a higher pitched whine. A Chrysler employee told me that beginning in 2005, Chrysler outsourced for cheaper bearings,and they were defective. He said they are no longer made. A whole new diff and axles had to be installed for another $2800. It still whines at all speeds now. Chrysler said "live with it!', and expect it to fail repeatedly. The case had been set wrong at the factory as well. There are hundreds of these cases on-line,but Chrysler refuses to acknowledge them.

I am writing because the front driveshaft differential assemble in my 2004 Jeep failed on January 4, 2008 after I put it into 4 wheel drive for the first time. I had it serviced the day before at a goodyear store. On January 10 the repair company determined that the problem was caused because two new tires, purchased from and mounted by the same goodyear service company, had been placed on the front and two of the existing tires with tread had been placed on the back per goodyear's instructions. The two existing tires were lower in tread than the new tires by about an 1/2 to 1 inch and they said this caused the failure. I checked this with a local Jeep dealer and they said that this would happen and that the tire company should have known this. When I brought this to the attention of the tire company that mounted the tires on December 1 and also did the service, they said they did not know about this potential problem and that I should have purchased four tires from them. The tire people had given a price on four tires but said that there was enough tread on the two front tires to continue to use them for a few months. They decided to move two front tires to back and put the two new tires on the front. The mechanics said that the problem was caused by using the four wheel drive with these tires. There is nothing about his in the owner's manual; it says "proper operation of four wheel drive vehicles depends on tires of equal size, type and circumference on each wheel. Any difference will adversely affect shifting and cause damage to the transfer case. " all tires meet this. Jeep/Chrysler said the car was out of warranty and even thought Jeep new about the problem; they said they were not responsible for fixing it or providing information to their customers about the problem. The goodyear tire company is stevenson tire services in fremont. (510) 792-3363. I have all of the receipts, repair check list and owners manual.

I was performing an oil change on the vehicle. As soon as I crawled under it to start, I noticed the right side of the front differential where the axle tube mates, was covered in diff oil. I took the vehicle to the dealer and was told it was "normal seepage". I find it hard to believe a gasket can only hold fluid for less than 6000 miles before leaking. Dealer refused to correct it.

1999 Jeep Grand Cherokee loredo exhibits the following problems: 1) lurch when shifting from park to reverse along with a noticeable 'thump' noise 2) humming noise at highway speed (65-75 mph) that graduated into a sudden 'pop' noise. This issue caused a loud grinding noise which I am now trying to deal with. Dealership informed me that this was a common problem in 1999 and 2000 model year for rear differential due to diffential supplier to Chrysler overtorqueing differential components. 3) driver's side door lock failure.

Rear end made a loud noise and after that the rear differential is very loud. It is like a grinding whining noise. After problem started occurring I have had minor transmission slips in first and second gears. This is the third occurrence of this problem in as many years. The first two times the warranty covered it but is has since expired. This vehicle has never been driven off road or towed anything or experienced a heavy payload. Doesn't seem right for this part to keep going bad like this with only highway/city light-duty driving.

My 1999 Jeep Grand Cherokee (gc) limited 8 cylinder quadradrive has given me nothing but problems since I bought it in October of 2002. I had the transfer seal replaced due to it leaking, the differential makes noise, the all wheel drive does not work (all wheel drive only works in low), and the tires lock up and make a noise when I am turning. It seems that their are other 1999 Jeep gc owners out there with the same problem. How about a recall to fix this problem?.

Excessive noise from rear differential. Dealer states components within differential are coming apart and that differential needs to be re-built. My cost is going to be between $1050 and $1300 for repair. I noted several other complaints from other consumers at the NHTSA site. Dealer states its a common problem. My previous 1988 Jeep did not have this problem. Any movement by NHTSA to force a recall or some adjustment from diamler-Chrysler or am I just out of luck?.

Heard a noise coming from the rear of the car took it into the shop and was told that it was the rear differential, and I was also informed that my transmission was slipping in 1st & 2nd gear. I had the differential repaired and the transmission serviced. We got snow this year where you would need the 4 wheel drive, well being I never had the need to use the 4 wheel drive mode I was surprised to find out that mine didn't work. Took it into the shop and was told that the transfer casing and transmission need to be replaced. So I took it to the dealer I bought the Jeep from. I let them repair my transfer casing and was told because I didn't have the exact same tires on the vehicle that is what caused the transfer casing to fail. The tires were the same size on the front and rear just different brands. They told me that I didn't have a problem with the transmission. I then picked the Jeep up and the roaring sound came back so I took it to the dealer to see what they thought the noise was I was told at that time that my front differential was bad and needed to be repaired and that the rear differential was also bad, but being I had that work done at a independent shop I had to take it back to them to fix the rear and then took the Jeep back to the dealer to have them do the work on the front. I am in the process of taking the Jeep back to the dealership because my Jeep is now pulling to the right. I was able to drive my Jeep for a week. I really have not had my Jeep since January I really think that daimler Chrysler knows there is a problem with the 1998 Jeep Grand Cherokee and I hope that something will be done about.
