    The tranny worked great for about 6000 miles and now is starting to shudder again and the surging in the engine is back also - - Talked to a woman who had an identical 05 JGC as mine and was told that she hadn't had any surging problems with this jeep but this was their 6th jeep and some of the other did have that problem. Jeep knows that they have a problem but will not admit to it seeing as other units also have the problem . Well , Chrysler will be out of business before long and then we'll all be screwed . . . :sick:

    if you had the rebuild done on 10/15/08, you should still be covered under warranty for the transmission. did you have the work done at a dealer? most places give you a 12 month/12K mile warranty with stuff like that. good luck.
  • My husband and i checked our brake fluid the other day and it was black as all get up. i have been having problems with the brakes not engaging untill the pedal is almost to the floor. i have an 88 jeep cherokee. i don't know when it had a fluid flush last i have only owned it for 5 months. if i have been driving a while the brakes start to get mushy and start to studer, but other wise the are just slow to react. i had them inspected 2 months ago and they where fine. i am not leaking around the master cylinder or anywhere else. i had one tech tell me that it sounds like i have an air leak in the line, but at the same time i had another tell me that changing the fluid will fix it. PLEASE HELP!!!!! just the flush is fine, but if i need a new master or booster i am screwed because i have a baby and i have to take my husband to and from work.
    thanks--paganmomma :confuse:

  • My 1999 Jeep Grand Cherokee does nothing. The engine doesn't even turn over. The odometer comes up with the word "done".

    The last time the engine started, it ran for about 2-3 mins, made a muffled thud noise and just stopped. It hasn't started since. Does anyone have a clue as to what is going on? Did my engine blow up or something? What does "done" mean? I'm at a loss.
  • My jeep burns up the coils in about a day. I have replaced the plugwires and the plugs. Rotor button and dist cap. I have also replace the ground wire to the block.
  • what's the mileage on it? i also have a 99. it's never been flooded...has it? how long have you had it?

    My 2000 Grand Cherokee rear rotor was frozen in place. I could not get it off due to limited work space around dust/splash shield. I did google search & found a site with pictures and how to break free which I wanted to share for all diyer's, Patience needed but this simple method worked for me. Another good reference site for JEEP info is

    i have a 2001 jeep grand cherokee and all of lights inside will flicker and the radio will do the same. my batery gauge will go up and down and it sounds like it wants to die. i just replaced the alternator. checked all of the fuses and everything is good. does anyone have any ideas???
  • skijeep1skijeep1 Posts: 5
    I had the same thing happen to my 2000 JGC and the problem was I need a new battery
  • smokebeesmokebee Posts: 30
    Before you invest in a new battery---disconnect the negative cable first the positive cable secondly---clean the batt posts and the inside of the cable ends till they are bright. R econnect the pos--then the negative to the batt. Get in the vehicle--put foot on brake and hold--Turn the ignition switch on-off, on-off, on-off. release the brake and start engine.This has worked for me on a 99--4.0 L engine.

    did you ever figure out the problem with the intermittent stalling ?
    I have a 1997 jeep grand cherokee limited, and I am having the same problem..
    Any suggestions ???

    I have replaced the battery, the Distributor Cap, rotor and the pick-up coil. It ran fine for 1 weeks, not one single problem. Then one night about 5 miles from home pulled up to stop light and the jeep just died. Ever since then the problem has gotten worse to now we can't drive it at all.

    Any suggestions ???
  • c_farooqc_farooq Posts: 20
    Try the coil pack and spark plugs? is the engine souding ok? does it miss fire? my problem with the jeep was to do with a switch on the driver side window. Once this was fixed, the car worked fine. Do you have other problems?

    I have a 2003 4.7 jepp grand Cherokee with a 601 error. The Jeep runs fine. I replaced the ecu and the new one, after being reset, started one time then develope the same 601 error. After all resets it last only one start. The jeep has has been running fine, with this error, for a year. It acts like there is a virous that keeps reinfecting the ECU.

    I have a 1999 Jeep Cherokee Sport. Bought new rotors, and after putting them on the front wheels wouldn't turn.

    I checked the sizes and the "stock" rotors are 1/2" (roughly) smaller in diameter. Auto Zone and a belvy of other places cannot help me. Maybe someone here has a part number or knows what they should be?

    The "stock" rotors given as replacements were 3115's (305mm), the old rotors appear to be 265-275mm. Same hat size and overall dimensions as the 3115's, just smaller diameter.

    We have searched and opened 20 boxes at Auto Zone (love those folks there) with no luck.

    Can anyone help?

    I have a 1996 4x2 Grand Cherokee Laredo. A couple of weeks ago I noticed a squeak coming from the rear only when I am driving forward. It does not do it in reverse. As the weeks go by it has gotten allot louder and I can not tell where it is coming from. As far as I can tell, it is coming from the rear and is loud. Any ideas or help would be very much appreciated. Thanks.

    The "99" through "04" GC has a known fault with the heater blend air doors, especially the automatic temperature control heaters, you may be experiencing this problem, symptoms are no heat on passenger side or drivers side or maybe heat on one and not the other, this is an expensive fix if it is the problem as the dash has to be pulled, but not all is lost, there is a guy on ebay who sells a fix kit you can install from under the dash it works and fixes problem for a fraction of the dealer cost, hope this helps, has an article about this problem.

    IU have a 98 Grand Cherokee that keeps blowing front diffs. Two in the last two weeks! I also have a 94 Cherokee scout that Im about to junk. Would it be poss ible to install the transfer case and front diff from the scout to the
    grand. I really hate the full time 4 wheel drive on the Grand to start with! I was in a pinch and got the Grand Cherokee for a good price paid $2000 and now have an additional $3000 into it. I was just going to put another junk yard dif in it and sell it but I dont want to screw someone else.

    I also have a '98 GCLtd and I removed the front drive completely. As I only use it as a road car I didn't see the need for 4x4. Take out both front drive axles but retain the stub axles to the wheels. Remove the prop shaft from between the diff and transfer case. You then have a perfectly good road car, with perhaps a little understeer, with less front end noise and no prancing about when starting off.

    My 99 has 94 factory parts on it. Found out the hard way like u.
  • c_farooqc_farooq Posts: 20
    Thanks for that might actually do that. DOes your transher box not work now? my transfer box is making some noise? if doing that wil help might do that. Is it just as easy to make it into front wheel drive, as its better in snow.

  • c_farooqc_farooq Posts: 20

    I am having the same problem.If you go left or right does it stop? if you turn left and it stops it means the problem is on that side and it could be a bearing. if it sfront its cheaper than the rear one. Also might be the diff. have you noticed any different with performance.

    hope this helps.
  • I have exactly the same problem with my 2004 Jeep GC. I bought it 2 years ago & noticed the same thing as soon as I drove off the Patrick Pontiac lot. I took it back to them & naturally, they couldn't find anything. Since then I had Elmer's, my regular mechanic, diagnose the steering column replacement and tell me to take it back to Patrick because it's a $1000 job. I did this, & again, they did not find this problem. I don't regret buying my Jeep; I regret who I bought it from. I'm going to Vision for 3rd opinion and then most likely will have my trustworthy guys at Elmer's fix it. Good Luck
