    Surely, looks like many persons have the same issue. I need to let our mechanic guy know your case, because he always neglects my complain. Could you inform me of the result after repair? Thanks--.

    Reply and followup to #1206 and #1207: My 96 did not have a hole w/plug in the V. So I had a mechanic drill one about quarter of an inch in diameter and insert a removable plug. He affixed an extension to his compressed air hose and inserted in to the hole as far as possible to blow out any debris. Works fine so far. check photo below..

    Yea, I'm not sure the hole in mine was from the factory or someone drilled it before I got the vehicle. But they put a removable plug there. I took the plug out because it didn't seem to seal very tight. I just put a bit of mold-able rubber over it and a small piece of duct tape to hold it in place. Works fine. Maybe I'll find another plug with a better seal. BTW, the photo doesn't show in #1209...

    Yes, weird, but the same thing happened to me on my 2000 Grand Cherokee. At night, radio and lights started flickering, then all the warning lights on the dash came on, and it eventually "died" completely at a stop light. Fortunately, it started again and I made it home. Next day took it to the shop and everything was functioning fine, no signs of trouble! Ugh!!!..You KNOW it's going to happen again.
    Any luck in getting yours fixed?

    Aaahhh, shoot guys! I'm sorry about the misinformation. I was going by the picture in my service manual (which I think is of a '99 model) and just found a similar looking hose in a similar location on my '98 and didn't thoroughly check it out.
    Mea culpa.
    By the way, I have not experienced this problem on my '98. Guess I'm apparently one of the lucky ones. ;)
  • Is the parking brake on?
  • I have a 2000 Jeep Grand Cherokee. My vehicle has done fine until a couple of weeks ago I was driving and stopped for a stop sign and the RPMs just kept dropping until it completely cut off. Now it has gotten to where I have to keep my foot on the gas to keep it from cutting off even when I am sitting still. This problem is continuing to get worse. Has anyone else had a similar experience? If so what was the problem and what did you have to do to correct this problem? Thanks, Matthew.

    My 1997 did not have a hole with plug either, but I found a perfect plug in one of my misc. parts drawers so I decided to give it a try. I was able to dislodge a fair a mount of debris in the Y shaped area above where I drilled the hole so hopefully this will do the trick. Thanks everybody for your comments, I hadn't thought of drilling a hole there.

    How are you? I am sorry to hear that you have this problem too. I have a 2005 Grand Cherokee with the F package as well and I have a lot of visibility issues. Overall, I love it though. I want to suggest a couple of other vehicle options for you. The three best SUV's on the market at the moment are the Toyota 4runner, the Nissan Pathfinder and the Nissan Xtera. In all honesty if you want the best SUV on the market go with the Pathfinder. Good luck, JP

    I have bougth a 93' JGC. I like it very much. But I do not know every details on my car. I do not have an owners manual. I live in Hungary and I would like to get a copy of this manual. I prefer an english version.
    I take with pleasure every possibility.
  • jerrymailjerrymail Posts: 3
    I'm the one with the '98 JGC: I think cleaning out the hole at the bottom of the plastic housing and using the silcone around the connection in the firewall has solved my problem. I've gone 5 days without any leaks! Good luck guys... :)
  • were you having trouble starting it, but then it would start after a few minutes? The dealer told me I needed to have eveything changed, not just the o rings. Did this solve the fuel pressure problem?
  • caphilldelcaphilldel Posts: 1
    I have the same problem in 1998 JGC SE. In my case it seems to be the fuel float. My tank is actually empty when my gaige reads 1/4 tank. Other than that (single problem) I have beat the crap out of this jeep & havent had anything to complain about. As a matter of fact, its hard to compare it to the new cars, because its been so reliable. I just hit 108,000 miles.

    Why is this happening and what may be the problem
    My jeep just started leaking coolant. At first my light cam on and said " Low Coolant". I thought it was most likely just low. I looked under the hood, and it was empty, or almost.
    I bought a pre mixed solution and emptied it in. 4 days later, the light came back on.
    I added more and see it dripping ( slow) from under the front passenger side up near the front.
    Any thoughts on what may be wrong, how screwed am I ? Cost wise etc. to repar.
    My Jeep has 168,000K. I just paid it off. LOL.

    Any thoughts would be great.

    Thanks in advance,

    It's hard to tell what might be the culprit without more information. That said, I'd bet it's either the radiator, a coolant hose, or the water pump.
  • kibbykibby Posts: 1
    I bought a 95 JGC a few months ago... When I turn the auxillary power on, right before starting it, there is a clicking sounds that sounds like a stop watch coming from the fuse box in the engine. When I pull the fuel pump relay and the auto shutdown relay out, the clicking stops. when the fuse box is clicking the jeep will not start. after the clicking stops, on it's own, it will start. after it sits for awhile, it will not start and the clicking starts all over again. Now, the clicking will not stop and I can't get it started... No one can seem to tell me what the problem is... Everyone is stumped... does anyone have any ideas?? By the way, the fuel pump seems to be working fine... Thanks in advance...

    Sounds like it may be starving for air. When you step on the gas a little in addition to adding gas you are also opening the throttle body a little and letting in more air. The first thing I would do is clean or replace the PCV valve and make sure the tube leading to it is clear. This is a common cause of this problem. Also check your air cleaner. If this does not work there is an adjustment to the stop on the throttle body, but you should not have to move it too much. If you do, there is another problem that needs to be addressed.
  • xscoutxscout Posts: 141
    Have you checked out the battery? Since you have had it only a few months you may not be able to tell how old it is, but you would be amazed at all the strange electrical problems that have been solved on this forum simply by replacing the battery, even when the battery would still turn over the engine.

    I have a 92 Jeep Grand Cherokee that I got used. It was ungaraged and has some body rust (and, presumably, undercarriage rust). I live in the Northeast where they use a lot of salt in the winter. By the way, this model has only the all time AWD (you can't turn it off) we obviously drive in AWD all the time.

    Sometimes, when you hit a bump at normal speeds (~40MPH), the whole front end wobbles and you just about lose control of the Jeep.
    My mechanic (who, granted, is a smaller, 1-man operation and doesn't have access to advanced diagnostic info like Jeep dealer would) has checked the ball joints, tie rod, and the shocks/struts and found nothing wrong.
    I thought my wife was exaggerating the problem until she told me to try it out for myself. I took the Jeep over a small bump (actually it was a partially sunken mahnole cover in a local road) at about 45 MPH and I nearly lost control of the thing as the whole front end was shaking so violently. I had to slow down to regain steering control of the Jeep. I believe I hit the manhole on the left (driver's) side, if it matters.
    My wife is 6 months pregnant and I told her to stop driving the Jeep until we can figure out what's wrong.
    I did some searching online in general and on this site in particular and couldn't find anything except some reports of tie rod failures on later model (2000-2001) Durangos.

    Is there something else wrong here or did my mechanic miss something?
  • darkstarpadarkstarpa Posts: 2
    Thanks for the reply. I spoke with my father about the issue. He said it will be the water pump most likely.
    Seems that I can fix for around $175 or so with labor and parts.

    I had the same problem with my bother in laws jeep. Check the on board computer for fault codes, Auto Zone does this for free, I replaced the crank position sensor and it solved the problem. A friend had the same problem and it was the cam position sensor.
  • 390bird390bird Posts: 5
    Jeeps can act funny with rust. There are sway bars and traction arms that run form the frame to the axles on the upper and lower area's of the suspension front and rear. I had similar problems with my brother in laws jeep after several inquiries and inspections I ended up having a friend who races or runs monster trucks check it out. He said the bars & arms control handling as well as the shocks. The sway bars are simple and look like a bent piece of 1/2 to 3/4 inch round metal stock. The arms look "U" shaped and connect to the front and rear axles then to the body. If these are fatigued by rust they will flex more and cause the jeep to handle extremely loose. This along with shocks can cause the problem your having. The impact will flex the suspension components & weight of the vehicle will counter and will repeat causing a "yo-yo" effect if you will. I would check these components for rust fatigue and the shocks. I would also double check the front end by jacking under the axle on each side as if the weight was still on the wheel & then check by jacking under the frame, " hanging the front wheels and check for loose components both times using a long bar under each wheel. This will give you more leverage in checking for loose or worn components which may be missed by the standard of holding the wheel by hand and checking for worn suspension parts. I replaced the rear arms two to three years ago for about $30 to $50 each. They may be the same or more. If the shocks are worn I would go with a premium grade shock.

    Hello everyone, newbie on the board here although I have been reading posts for a while. Can someone give me some advice on a problem with my 01 Grand Cherokee Limited with Quadra Drive? As I accelarate on the highway, when I reach 50 mph, there is a very distinct and bothersome "shimmy" in the steering wheel that has just developed. As I pass 55 mph, it goes away. It seems like only between 50-55 does this happen. I have taken it to 2 independent shops (just spent over $500 on the brake upgrade kit at the dealer less than a month ago and I want to avoid giving them any more money right now!) and neither one can find fault in the tires, rims, suspension components, brakes, or alignment. Both shops have fully examined the Jeep and fail to find a mechanical cause. The second shop tech made mention that he thought it might be something in the electronic 'Brain' that controls the Quadra Drive system that might be causing the 4WD to try to kick in. Has anyone heard of this? It really feels like a mechanical problem to me. Can anyone give me any insight? I would surely love to get a few opinions before going back to the dealership. It's not a huge problem but it is bothersome, and since I'm about to take it on vacation with the family, I definitely don't need any nasty surprises. By the way it has 77K miles and has never had any major transmission or engine work done. Any help appreciated!!!

    My turn, my brother in laws 1994 Jeep grand cherokee, auto trans, when making sharp turns like into a parking space starts to make very loud noises, "people turn to look" and you feel the front end kinda hop. This is even worse when in four wheel drive, like the whole front axle is binding on turns.? I have checked everything I know & to me it seems as though both tires are trying to turn like it is one big long axle or maybe the wheels are turning too far~! My guess is the right and left should "slip" independent of each other. He thinks he had all the fluids changed, but can't find the receipt so I can be sure. I was told "I thought I heard or read..." when changing the axle oil there is a Chrysler "additive" you have to put in to let the limited slip more slippery or to prevent this binding. My parts store contact thinks I was off my meds or something.

    The other is his AC doesn't seem to want to drain outside. I have pulled the entire interior and checked what I can of where I think the AC condensate should drain. The condensate drains into the passenger side rear and front. I see no draining outside. I found alot of dirt in the frame rail where I think it is supposed to drain and cleaned this & what seems to be the hose or drain hole. It worked for about a day or two then started flooding the interior again. I have tried pressure washing and air pressure. Any ideas's?
    Any ideas or input would be "FOREVER IN MY DEBT" :confuse: :sick: :( :mad:
  • div2div2 Posts: 2,580
    It sounds like you've got a case of what we Wrangler owners refer to as "Death Wobble"; any mechanic who claims to knows anything about Jeeps should be well aware of this problem(go to any Jeep forum and search "death wobble" to see for yourself). DW can be caused by any number of things. In your case I would first check the tire balance(dynamic balance the tire/wheel assys-weights on both rim edges), the steering stabilizer, any and all rubber suspension bushings, and the front end alignment. This assumes that your mechanic knew what he was looking for when he inspected the other front end components. He might be a nice honest guy but it appears that his Jeep knowledge may be inadequate to solve your problem.

    Philpomy ... I also have a 98 GC, and have had similar problems with the interior lights flickering on and off. I tested the 4 door sensors and they appear to be working properly (volt-o-meter tested), I suspect my problem is within the rear hatch sensor. Have you continue to have your problem? Any resolution?
  • wlbrown9wlbrown9 Posts: 867
    Best place to start is the steering stabilizer (shock absorber like). Probably $30-$60 bucks. Folks say it happens more often on Jeeps with lifts. On non-modified Jeep it is probably the stabilizer.
  • rschunkrschunk Posts: 1
    Hi...sounds like the 'death wobble'...I have a 93 JGCL that exhibited the same symptoms. Turns out that replacing the steering stabilizer fixed the problem.
  • Have you replaced you spark coil? I have had the same symptoms in the past and have had three coils go out within 115000 miles on my 94 wrangler 4L.
  • jkramjkram Posts: 17
    I have the exact same problem. My 2005 Jeep grand w/hemi is bucking and hesitating. Your description is perfect, slight grade giving it throttle. I brought it back three times. They changed the oil 'cause DCX, told them to. I am a mechanic on heavy equipment so I know it is not running right. They said give it another 3,000 miles to break in. I'll have a stroke driving it like this. Please, someone get some action on this. I literally spent $38,600 on it and I can't stand it. It is my fifth new Jeep in a row, and I never had any troubles before.
    Help, Joe
