Hi Hobartus? I've run it on rear wheel drive only for over a year now. Your 'reputable transmission shop' is looking for business. Forget them. If there is no resistance from the front, the transfer case assumes the wheels are spinning without grip. It therefore applies all the torque to the rear shaft, where you want it. I would only recommend it for road use but remember, it does cause some understeer and maybe a little tyre scrub on tight turns.

I have a 04 4.0L grand cherokee. I have a bad pulsation while braking...first instinct was to change my front rotors and pads...wrong. Even my local shop missed it. Took it to Jeep, couldnt find anything but pointed me toward the rear brakes. I felt the pulsation more so in the brake pedal. So I change the rear pads and rotors. Pulsation still occurs however I found that one of the pads on the driverside was not worn. Passengerside both pads wore half way. I check the pins the pads slide on but they work fine. I take it back to jeep and they cant find anything wrong. They checked the pins, pads, caliper, rotor but still the pulsation is there. Sometimes its there while driving and i'm not even on the brakes. Does anyone have any other ideas???

Jeep Grand Cherokee Limited 2002 warmed the engine 5 to 6 times a problem of engine fan was replaced. get started with a sound failure in 2 valves or lister. get started at 4 months to spend the 2nd cylinder with water most notable failure. now the oil pressure drops to 0 after the engine warms up and this stopped running pressure is normal. I'd like your opinion.

change the oil pressure switch.it's next to the oil filter. either that,or your motor's trashed,oil pump?

I once had an egnine sludge problem. The oil pump pickup in the pan has a wide nozzle covered with a screen. It can get clogged as it sucks up oil. Before buying a new pump, drop the pan and clean everything including the pickup tube if it can be removed. Then install a high performance oil filter.
If you change your oil and it looks dirty right away or looks dirty within a week you have sludge in your engine. But if clean, you could still have a clogged screen or tube.
If you have sludge at top of engine, you will have to remove manifold and phyically clean it out. Hope you don't have that.
When I was working on my car it would drive a few miles OK and then oil pressure light would come on (even after cleaning pan). I had to use Gunk engine flush several times. Hi perf oil filter helped a lot.
It involved a lot of hard work. Most mechanics would not make this effort on somebody else's car.
If not an experienced DIYer, get Haynes manual and follow all safety precautions.

Sounds like it is the deive shaft itself. When you pulled it out, did you check it for wear, clicking, movement, etc.? When thrashed, these things can make quite a howl!

Definitely sounds like a bad drive shaft (typically the one with CV joints). Replace the shaft with a new one with U-Joints (a little over $300). Goes in with 10 minutes' work. Several good suppliers out there.
#4668 of 5143 2004 4.0L GC has really rough/sputtering idle and tapping noise
Jan 05, 2010 (12:50 pm)
I have a 2004 GC with less than 49k on it I am the second owner and I have had it for a year. I am a rancher so I drive it off road some but not hard, and I have kept up on oil etc. Its always run great until a month ago when it suddenly started a really rough idle and vibration when stopped, it feels like it wants to die but never does and also a sound like a bike with a card stuck in the spokes on exceleration. None of this seems to affect preformance but the check engine light is on. I have replaced injectors, ignition coil, spark plugs. My mechanic has checked everything and can not find what it could be thats causing this. I think it might have something to do with the computer, but I hate taking it to the dealer because I am a young woman and they always try and give me the run around. Does anyone maybe know whats causing these issues. I have to drive it some but I am taking it easy even though my mechanic cant find anything and says everything looks fine. Please help I love my Jeep and want this to stop!! Thanks

The only thing my mechanics diagnostic came up with was the front cylinder not firing... so they replaced the injector. And that didn't do anything, so thats when they replaced the ignition coil. Does the dealership have a different system to check the codes??
