#1009 of 5143 Re: 1998 Jeep Grand Cherokee - front differential problems [philpomy]
Mar 30, 2005 (3:14 pm)
While any failure is possible, don't buy the explanation that "jeeps do this" jeeps use DANA axles that are in many other brands. (in one incarnation or another)
usually if the gears in a Diff aren't set properly, they wear out very quickly because when out of adjustment, they can't take the forces. Since your rig is a 98, it seems that that wouldn't be the issue since it's lasted this long and wasn't humming loudly. Essentially the same front axle is in all wranglers, cherokees and Grand cherokees produced from 1984 on, so there a a lot of them out there.
Another thing that can cause distruction is bearing failure, if you were low on fluid and they got too hot, you can have problems with them failing.
Lastly, Many 98's use a VC and when it fails, it essentially means the Jeep is in Part time, all the time. this can add a lot of stress to the driveline because of binding and will break the weakest part in the system, could be a u joint, the TC chain, a CV joint, or the spider gears) eventually.
But you don't have to have a VC failure to get it to lock, you just have to have different size tires on the front and rear. if you have different sized tires (or different pressures) you will get the VC to engage, on the road, stressing your system over time.
You asked for specifics from him, and you got none! Don't let them be disrespectful to you!
Specific answers should have been like,
The carrier broke, the axle shaft sheared, the spider gears broke, the left side bearings are toasted, etc.
once you know what actually broke, you can look at contributing factors
your $1600 estimate should include exactly what the mechanic is replacing. detailed and itemized.
For what it's worth, resetting the gears for a diff is about $350, labor when the Diff is on the rig at an axle shop. And that includes putting all new parts on while you're setting it up and putting new gears in.
so what new parts are you getting?
new wheelbearings ~300? (prob not needed)
New Ring & pinion ~150? recommended to change if that's what broke.
New axle shafts & bearings <300 may not be needed new carrier <100 may not be needed but is not expensive new carrier bearings <50 recommended to change Install kit, seals bearing etc, <90 required new sealant on the diff cover <$5 required new oil required <10 you probably don't need all that, & it's under 1600. So I would look hard at what they're charging you. Ps, since they have to take so much off,it shouldnt cost extra to put new parts back on. they may be adding new front brakes in too? but I didn't read the estimate. What can you do different? Make sure your tires are the same size. Make sure the axle is full of the right oil. Check to ensure the VC is not malfunctioning. PSS when brakes are worn too much, they make a terrible metal on metal grinding. when this situation occurs, one could probably limp to a service shop, but if there was freeway driving involved, it's safer to tow than to worry about having to have a panic stop and not having front brakes. So the decision to tow is a reasonable recommendation when you have metal on metal because of worn brakes. a brake job with new front rotors and front pads, and maybe back pads, can be done for $500 at a shop. Base on what you said, I would have to eliminate this possiblity of it just being bad front brakes before I get any axle work done. I'm suspisious of the mechanic, because their specific answer was, "when we opened her up, she was in a hundred pieces". They should be able to show you one of those pieces, btw. one the jeep site, there is a place where you can put in you last 8 digits of your VIN and it will tell you if there are any missed recalls.
#1010 of 5143 2005 Jeep Grand Cherokee problems
Mar 30, 2005 (7:37 pm)
Here is one for you. I purchased an 05 jeep grand cherokee with the hemi engine 4 months ago. 14 days ago the check engine light came on and to date the dealer, working directly with the service people at DC can not figure out what is wrong. They replaced every possible part and still they are getting over 30 codes and can not resolve it.
When and if I ever get this piece of junk back I probably will be doing the same thing (taking a loss) and getting another vehicle (not a DC vehicle though)

Other than my rotors, I've been kind of happy w/my '04 GC. I've used my 4wd during the winter in OH and had no problems what so ever....... I would recommend getting the extended warranty through Daimler-Chrysler. I purchased the maximum care for like an addt'l 1500.xx but it covers well past my lease.

#1013 of 5143 99 JGC Engine Overspeed
Apr 02, 2005 (2:48 pm)
My 99 JGC (80,000 miles) has run very well for me except for one problem that no one has been able to correct. After a long highway drive of over 6 hours the engine will over speed about 300 rpm and then come right back down to normal engine speed for the speed I am going at. The car shudders a little but I don't lose power during the event. It will last at least 30 minutes and sometimes to the end of the drive.
Has anyone experienced this?
#1014 of 5143 2004 Jeep Grand Cherokee Problems
Apr 02, 2005 (6:20 pm)
I have a couple of problems with my 04. First is the heating in the car smells awful for a couple of minutes and then goes away. Second the steering gets stiff and it is hard to turn out of a parking spot. Third, lately when I stop at a light I listen to the engine and it sounds like a diesel. Also the back interior light where the trunk is doesn't turn on when I press it but it turns on when i flick the switch on the steering wheel. I dont know what the problem is with this truck. Can somebody please tell me whats wrong. All I have had with this truck is problem after problem. I dont know why because I do everything I have to do to take care of the truck and I baby this truck. Do you think it would be easier to trade my jeep for another chrysler product than to take it to a dealer for a new lease? Thank You

Did you try checking the throttle mechanism...sounds like it needs lubrication.
#1016 of 5143 Stall out after restart
Apr 03, 2005 (9:27 am)
I have a 1994 Grand Cherokee, can't complain about it because it has ran great for the last 3 years with no problem except an A/C leak. I've read through the forum and compared my problem to some similar problems. The car will start and run fine until I turn off the engine and try to restart, then it will lope and die as if not getting fuel. I replaced the fuel filter, but still after waiting for about 30 minutes engine will start and run fine for however long I decide to drive. Stop the engine, run into the store come back, engine lopes and dies. I was thinking about getting a can of injector cleaners or water evaporator and poor in the tank. One other thing, now one eighth tank seems to be empty I put more gas in and it started but the problem continues. I think it may be the fuel pump, any second opinions, thanks

i have a 2005 grand with the hemi, its missing and stumbling when accelerating after shifting into higher gear then just drops the rpms to around 1100 and it chugs from there until you floor it, or it shifts on its own ,im wondering if anyone has found a fix for it yet, i cant find a dealer that can figure it out
