    My 1995 Grand Cherokee was doing the same thing off and on so I took it to the dealer and they said it was the PCM (Power control module). They replaced it at a cost of $850.00. I haven't had a re-occurance since then. Hope this helps.

    We just got a Jeep Cherokee Lerdo 1990 from my sister in San Diego, The problem we are having though and cannot figure out is , that is isnt shifting correctly, We have been told it is the Throttle postioning sensor, it doesnt want to shift right first of all and second it revs up and down when your driving it, after you get to about 60-70 miles per hour, it stops...any help of clues would be great, i am a newby at this Jeep thing....all i have to say i think they are pieces of *#@* . I would very much like to figure out the problem, We have a strait 6 in it, and just replaceed the shifting cable, yesterday, :sick: ">

    All you have to do is replace with aftermarket rotors...not real expensive ones either...just as long as they are not the D/C rotors. I spent less than $100 and fixed my problem for over 50,000 miles. Part of the problem can be the calipers....original calipers tended to stick on the slide pins.. I had one stick after putting on the aftermarket rotors...got hot enough to warp. Once they cooled down the warp left. Greased the slide pins and cured that problem. So, the $100 rotors would take a real heating up and revert to straight again... D/C factory rotors warp with only a little heat... Total Crap. Best thing is to avoid D/C vehilces... Even GMs are much better :-) at least that is my opinion.

    Has anyone come across a solution for stalling. My JGC stalls fairly often, when I back out of my driveway and put the car into drive- the engine cuts off. Naturally the dealer is "unable to duplicate my problem" and say that there are no other reports of such an issue. Perhaps I should refer them to this forum so they can read for themselves all the stalling complaints... Thank goodness it is a lease- As soon as I turn the jeep in, I am headed straight for the Nissan dealership!
    Any insight would be helpful! Thanks.

    I got that same letter. I am not a fan of CA lawsuits either, but for the money I have put into mine having my rotors replaced 3 TIMES in the past 4 YEARS, it is a little different story. I have also just got done putting in over $3000.00 to replace both front and rear differentials and replace all twelve lifters in the engine. (3 lifters just broke one day...go figure)...I have stopped going to the Jeep dealers because of some of the BS that they had told me regarding the brakes years ago. I have a 99 JGCL with 107000 miles on it. I bought it 5 years ago with 63000 miles on it.

    I have a 98 JGC and the check engine light came on. I took it to Autozone and the computer gave the code P0702 Speed Sensor Malfunction. I bought the sensor and changed it my self, restarted de PCM system (unhooked the battery for 15 min.) the engine light came off, but when I drove it and right after the first gear came in the engine light came on again. Took it again to Autozone and still same code. I changed the speed sensor again, thinking that I had a new bad one, and still it did the same thing, I even changed the harness that hooks up to the sensor. I took it again to autozone and it reads the same code. This is what the troubleshoot reads exactly:

    Troublshooting P0702
    The PCM has determined that a malfunction exists in the electrical circuit for the transmission control system.

    I would appreciate any suggestions you might have.
    Thanks,

    So I drained the diff and cleaned it out real good, filled back up with new gear oil and still getting the same sound. No idea what's causing this and I live in Italy so there's not an abundance of dealers or mechanics that are familiar with Jeep...not to mention the language barrier. I've included a quote from my first post explaining the problem. Any help??

    "I have a pretty pronounced whirring/whining sound that seems to be coming from the front differential. This occurs anytime the wheels are in motion. The sound is pretty loud, and a dealership mechanic told me (over the phone) my front end is probably going out."

    I put up a post on here, i need some help or opinions, I have a 1990 Jeep Cherokee Laredo, Has a strong motor, and many new parts, the problem is when you get in it to drive somewhere it doesn't want to shift, it feels like it is getting stuck once you do get it it to shift it is ok other than it surges, while driving on the freeway, the RPMS go up and down erratically, could just be sensor, I am not sure i am unfamiliar with Jeeps, So any advice would be very very appreciated.... :sick:

    Got a similar noise on my '98GCLtd, especially on the over-run. Had it when I bought it, still the same now after oil change and several thousand kms. I just turn the radio up. If it falls apart I'll know what the problem is.

    Cheers...Jim

    My problem is fixed!!! We had to replace both speed sensors the output and input, both located just inches away and very easy to replace. Hope this info helps someone.

    Thanks,

    JC

    Is the check engine light on? I had a problem with the speed sensors on mine and they were causing for the transmission to shift roughly.

    Thanks,

    What was your jeep doing?
  • hectorchectorc Posts: 5
    They are on the driver's side of the transmission, one is located just about where the transmission connects to the driveshaft. The other one is a little to the front almost it the middle part of the transmission. The computer was giving a Code P0702 with the "check engine" light on, Is yours on? I paid a total of about $90 for both sensors.

    If you want I can send you a picture of the whole thing.

    Good luck,

    JC

    Mine was doing the same thing, the main thing of my problem was that it needed wheel alignment, but I waited and the front passenger side tire wore out the thread on one side about an inch wide and that was enough to make the leaning worse. So I replaced the 2 front tires with new ones and had them aligned and solved my problem, I can go perfectly straight for about 2 to 3 blocks, Good Luck

    Had much the same noise as you. I have a 97 Limited ZJ. Put the Jeep on a dynamo because of the AWD. My mechanic determined the whine was from the driver side wheel bearing hub. As precaution I had both hubs replaced. On these models replacing just the bearings is a B*****. Replacing the entire hub assembly was more practical. My expense was the hub cost only. My mechanic (a friend) only wanted an 18 pack of beer to cover labor. Lucky me. ;)
  • Hey Matt,
    Did you ever find a solution? My JGC has started to do the same thing except only when I use the AC. I think its the pump but maybe the hose, i just don't know. I take care of my car and no accedents, would something like a pump just wear out on her?

    appreciate any info....

    Now I have another problem with my JGC. The rear windows stop working one side at a time. One day the rear driver's side window stops working and the next day the rear passenger's window stops working, and the driver can not control the windows either when they stop working. Is it the motors? What is it? Thanks

    I too have the vibration issue on my 2005 jgc w/hemi. dealer told me it was tires out of balance.
  • tcrocketttcrockett Posts: 6
    I have this exact issue at speeds between 75 and 85 mph. I took it to the dealer for repair. Was told it was tires out of balance. Thought I was going to see the passenger seat fly through the sunroof!
  • 40,000 miles on a 2005 grand cherokee v8 hemi. Have had it in the shop for the vibration issue, for an acceleration issue and now the drive train actuator is being replaced.
  • I'm having more of a pronounced skip or bucking is more like it between 60-70mph...over 70 seems to fade away and prior to 60 no problem.What is the Drive Train Actuator?Anyway to discribe the problem is as we all must have had at one time or another in our driving careers...water in the gas....that's the best I can discribe the problem..The bucking is radom and not in any special rhythem....It is a major skip which can be felt in the passenger seat and throughout the vehicle also...

    I have a problem with my 05 Jeep w/ HEMI always searching with the transmission and torque converter and it surges and the tack goes up 2 or 3 hundred RPM's looking for a smooth place and I'm being told by the dealer and chrysler that this is normal and I have 9500 miles on my jeep and it's been doing this since it has 3000 miles on it. They know whats happening and don't know how to fix this problem so their answer is to say it's normal and I'm just wondering if there is anyone else that has this problem. :confuse:
  • http://www.wkjeeps.com/tsb/tsb_wk_2100506.pdf, check this out for vibration problem. It is a service bulletin for a software change that should eliminate noise and vibration from transmission harmonics.

    I've been reading through a lot of these posts, never having been here before, and I find it to be a bit disheartening. A lot of people having a lot of problems with their JGC's.

    I own a '96 model and I haven't had a lot of trouble, but I have experienced some. I have replaced the break rotors once in the 4-1/2 years I've had it. I do have an AC issue that I'm putting off dealing with til I get some spare cash. I have experienced the "death wobble" that does indeed scare you to death when it occurs. Glad to find out that replacing the steering dampener cures that.

    But to address your particular problem, I faced a similar issue last spring. I would be driving down the road at average speed when all of the sudden, with no warning, my JGC would just die and I would coast to the side of the road. I would sit there for 30 secs to a minute and then restart it and drive off as if nothing had happened. Over a period of 3 weeks this happened about 6 times. I first discussed the problem with friends at work and one said he had the same problem with a Jeep he once owned. He said it turned out to be a faulty crank position sensor (CPS). So I took it to my mechanic and wouldn't you know it, he couldn't get it to repeat the problem over two days of having it. His suspicion was, among other things, the CPS so I told him to just go ahead and replace it (about a $90 part). Since then, the problem has not reoccurred.

    So, you might talk to your mechanic about that and see what he thinks. Hope this helps.
  • What is exactly the drivetrain actuator? I have noticed certain characterstics with the acceleration in my jeep. Hopefully i dont have to put it in the shop again, but if you have a second tell me more about how your jeep is driving and why that part must be replaced. thanks for your help!!!
