My vehicle has 51k miles I had it checked for a noise coming from the rear. I'am told that the Diff. is going. Is this unusual for this vehicle. I need to know if it can be repaired or must it be replaced. Please give me approx. cost and comments.

Thanks

  • I go to a local car auction and in the rules and regulations there is a list of exclusions. One exclusion is Jeep differentials. No one else, just Jeep. I thought that was strange.

    Differentials can be repaired, sure, but sometimes it's easier to just put in a used unit. If this is some kind of chronic failure then you have to check the used unit carefully.

    Usually such premature failure is a result of poor assembly or machining at the factory.

  • It all depends on how you use your Jeep. Have you changed the Diff gear oil according to the owners manual?? It has to be changed if you tow alot or go offroad, especially if you go through water. If the vent hose comes loose it can be easy to get water in the diff. I know that some Grands had a problem with thir allumnium diffs but don't know much about it. If it is a 2wd that never leaves the pavement, sees water, or tows then it is a premature failure IMHO.

    Good luck

    i agree with the host.a differential is probably the most durable component on the vehicle.not changing the lube is not going to cause a failure at that mileage.unless as stated water entered the unit.if water got in,there is going to be water in other components.the rear end was probably assembled by a dude on a friday who was thinking of a wild weekend.

    Had a '99 Laredo (towing package has a 3.73 ration that is different than the non-towing package). Rear end whining. @ 23K miles rear end rebuilt under warranty. Comments from repair ticket "Test drove. Found rear axel has growl sound and bad diff bearings. Necessary to replace front and rear pinion bearings and both side carrier bearings." Note these are June '00 prices and the apparent charge to DC for parts and labor. Parts including lubricants $182.98. Labor was $181.16 or total of $364.14. Not sure if there are more parts that could need replacing depending on the wear/damage.

    Hmm...looks like from that repair that you can access everything without taking the diff out of the vehicle.

    Yes, water intrusion would raise hell with bearings, like if you did a lot of off-roading through creeks or boat-launchings.

    You see a lot of TV commercials with Jeeps crashing through rivers but this is really a stupid thing to do regularly. Not only do you have to worry about leakage into the diff/trans cases, but also having the air intake suck up water and hydro-lock the engine. Not fun.

    such a problem with its rear diffs in Grand Cherokees that it now sells the entire unit, axle to axle, for under $500. Check with a Jeep dealer - the problems are very common. (I was a Chrysler/Jeep service manager)

    Since we don't have an active topic on Jeep Grand Cherokee issues, I slightly altered the title of this topic so we can discuss all problems.

    I ALSO OWN A 99 LAREDO JGC 2WD. AFTER ALMOST THREE YEARS, MY WHOLE DIFFERENTIAL BLEW OUT. SUPPOSEDLY WHEN ONE OF THE BEARINGS GOES, THEN ITS REALLY TO LATE TO FIX JUST THE ONE. I USED TO HEAR THIS GRINDING NOISE IN THE REAR DIFFERENTIAL, SO I HAD IT CHECK OUT AND THEY TOLD ME IT WAS A WHEEL BEARING. THEN THEY FOUND OUT THAT IT WASNT. IT WAS MY DIFFERENTIAL. SUPPOSEDLY, THERE WASNT ANY FLUID IN THERE. NOW, MIND YOU, THIS IS COMING FROM THE DEALER. ANYWAYS, I HAD TO REPAIR IT AND IT COST A LITTLE OVER 1 THOUSAND DOLLARS. I HAVE THE DIFFERENTIAL FLUID CHECKED EVERY TIME I CHANGE THE OIL, SO I DONT KNOW HOW THAT COULD OF HAPPENED? I DONT EVEN OFF ROAD, JUST DRIVE IT ON PAVEMENT...????

    Have 43,500 miles on our JGC, six / select trac. Noticed a whine from rear axle, had the fluid changed to synthetic at local garage. No change.
    Took the JGC to local dealer (mine went out of biz). They drove it, said it was the bearings and I asked what is Jeep going to do about it. They replied they would repair for $200, half the normal cost. I approved but when they took off the rear diff cover, the ring and pinion were worn with chips missing off the gear. They replaced the ring and pinion / bearings / etc for the same $200. Good Deal.

    I just had to have the bearings in my 96 replaced for $780 by the dealer. Only 57,000 miles, serviced according to the schedule, no trailers and almost no back roading. Wrote a strong letter to the factory suggesting that they should reimburse me. Has anyone been successful with this approach? How long can I anticipate driving before this happens again? This could get expensive.
  • desertrat5desertrat5 Posts: 85
    Since my last post, I have received a check from Daimler Chrysler for the cost of the parts or about $311. I have also found that there is a TSB on the subject of servicing procedure changes to extend the life of the differentials. Sounds as if there is a true problem.

    My mechanic informed me that my real main seal is going to go soon, which would require me to have the transfer case removed, obvioisly a big operation. I have a 95 ZJ w/110K. What kind of dollars to fix it are we talking here?
  • kkuligkkulig Posts: 150
    Unfortunately, the labor alone will be enough to make you cry. That'll be 90% of the total bill.

    I purchased a 98' JGC a few months ago at a dealer in Milwaukee. It has 45000 miles on it and runs great. Has the "quadra-track" 4 wheel drive system with the 5.9. The problem is,at or around 60mph if I let up on the gas I hear a whirling noise coming from the front axle's. The noise seems to fluctuate from the left front axle to the right front axle. Does anyone know what I should do,or can do to fix this very annoying noise. Thanks....
  • kkuligkkulig Posts: 150
    tpeltz...

    JGC's have experienced many complaints about drivetrain and axle noise. All one has to do is go back and read through the older threads out here. The problem is that there's no sure-fire way to pin down exactly what the problem is. People have had differentials, wheel bearings, drive shafts, u-joints, transfer case viscous coupler parts and seals replaced. Any one of these things can be the cause.

    First, I'd suggest that you visit the NHTSA website at http://www.nhtsa.dot.gov/ and look up TSB's and recalls on your model year. This is a free service. From the TSB titles you may recognize the problem your vehicle is experiencing. The main body of the TSB isn't there, so you won't be able to read a description of the parts and procedure required to fix the problem. Your dealer has the full TSB and you may be able to point him to a specific TSB to look at.

    The second thing is to take your vehicle to a reputable dealer and explain exactly what your vehicle is doing. Obviously, the service tech needs to take it for a test drive. Preferably, you should go along to make sure the tech hears the noise and under what conditions it appears. If they can't hear it, they can't fix it. This is the dreaded "could not replicate problem" we all see printed on the work order when we come back to get our vehicle after a service appointment. Make sure they experience firsthand what the vehicle is doing, as they can't fix what they can't find!

    That's not much help I know, but that's where everyone has to start. Unfortunately, there's going to be frustration, maybe a lot of trial and error before they locate and fix the problem, and yes, it's not going to be cheap to fix. That's the reality of vehicle repair work today. Good luck!

    zueslewis mentioned that you could by an entire unit for $500, but my dealer is quoting me $1400... has anyone been able to get this for $500? This will be the 2nd time in 2 1/2 years that I will be replacing this part and would be extremely happy if I could find it for $500.
  • zueslewiszueslewis Posts: 2,353
    while I was service manager at Milford Chrysler, Milford, PA. Never more than $480 for the part, plus two hours labor. DCC actually stepped up on this one - if your dealer doesn't want to play, it's because the parts department only makes $30 profit on the DCC-sponsored part and well over $400 if they order through regular channels.

    we have enjoyed our '00 JGC except from time to time the engine dies. Prior to last Friday, it had always been upon coming to a stop. Last Friday it died at 65mph. Restart is alwasy successful, but the "co-pilot" tool cannot detect the problem. Heard something about a crank sensor? Any help.
  • jc808jc808 Posts: 3
    As we were on a road trip 170 miles from home in a remote location our 01 JGC came to a stop and died. Warning sensors indicated check guages. Nothing was leaking or overheating. 24 hour roadside assistance towed us to the nearest Jeep Dealership 20 miles away which was closed (sunday) long story short we had to spend the night in the middle of no where. Dealership said Distributor seized and Cam sensor went. Anyone else have these problems????
  • kkuligkkulig Posts: 150
    What engine are we talking about here, the I6 or V8?
  • jc808jc808 Posts: 3
    I6 did it to me. Truck has been maintained and garage kept since purchased. I'm the original owner.
  • kkuligkkulig Posts: 150
    I believe you're correct that it's the crank position sensor. Seems from the posts that this is a fairly common problem on the I6 engine. Don't believe I've ever heard of this complaint on the V8 engine. I'm sure the dealers have the TSB on this.
  • I would like to hear from all Jeep GCL owners who have had problems with thier from brakes - rotors I have 53k miles and have had 4 sets of front rotors on the car - there is a tsb out but chrylser will not do anything.. We need to sue and show this company they can't do this - I would also be interested in hearing from a lawyer - I called the NHTSB and they are getting tons of calls about this problem email me at jlfjeep@aol.com
  • willie37willie37 Posts: 1
    I own a JGCL and has 97,500 miles. I hear a whining, buzz or moaning noise from cold transmission when I reverse in gear. I checked the TSB and does not tell me the problem. Can anyone who had the same problem or similar tell me what's wrong with the vehicle. I do not want to take it to a mechanic yet. I'm afraid I might get robbed.

    I just replaced my 4th coil on my 1993 JGC 6 cyl. with 82,000 miles. The engine died while my wife was in the #2 lane of I-5 S/B in Del Mar, CA. The mechanic thought it was the crankshaft sensor but it turned out to be the coil-again! The last coils were replaced 5/02, 1/00, and 10/98. Anyone had similar problems?
  • bmb1373bmb1373 Posts: 8
    I've noticed a lot of people with bearings and coils problems. Just sounds like a couple of defective parts. The most common problem I've seem, talking with people at work, is tran. fluid and oil leaks and ABS problems. I have a '97 JGC with 65k miles. Jeep already recalled the front rotors so no problems there. I've had to replace both seals on the FWdrive shaft and center diff. and now there's a leak in the rear. I just assume its normal wear and tear on snow bound roads. The only problem I don't understand is when I reach 70 on the expressway the ABS light goes off every time just while driving.
    Despite all these concerns, everyone I know who has a leaky Jeep still plans to by a new one, including myself in the next couple of months. I rather have a leaky Jeep any time than a Ford pulled over on the side of the road..
