I am hoping you are willing to help me too! I am losing my mind trying to figure this out on my 2002 Jeep Grand Cherokee Overland. I am not positive if my problem is exactly the same, but it is very similar. I have a grinding noise that sounds like it is coming from the driver side front. It has a low grind that continues anytime the accelerator is engaged. It couldn't be heard by others originally, but now even the passengers can hear the grinding. It isn't loud and annoying, but just unsettling. I have replaced bearings, had the transmission broken down looking for a problem, etc. It also "clunks" when making deep turns and shakes when braking with a sharp decline in speed on a downhill slope, but I am unsure if these are related or just more problems. Any help or insight would be VERY much appreciated!!!

the only other thing that comes to mind is the differential bearings or the spindles that mount it to the main crankshaft...but now i'm getting into the realm where i'm b/s'ing

if you have AWD it sounds suspiciously like the transfer case. an inspection of the transmission wouldn't have found anything if it is the transfer case. you'd need to provide more details, but the low-level grinding might be the tc bearings or a loose chain.
 
as for the turns, you could have a worn axle boot or bad cv joint. if you hear a popping sound when the wheel is hard-over, it's another indication of a bad cv joint or u joint.
 
it sounds like you have warped brake rotors.

Okay...I did a few "tests" last night on my way home from work. I agree that it probably is not the transmission. When I said the low grinding sound is anytime the accelorator is engaged, this was incorrect. It is anytime the vehicle is in motion. If I am stopped, you do not hear the sound. However, if the Jeep is moving...even while shifted into neutral...the sound continues. Over drive on or off does not make a difference either. I do have AWD, so do you still think it is in the transfer case? To describe the sound a little better, it is a combination between a low grinding and the sound large thread tires make on the road....but I don't have large thread tires and the sound did not change when I put new tires on before winter. Are there any specific questions I could answer to make it easier to diagnose? I really appreciate the help! I would love to get this fixed!! This Jeep has just been one problem after another lately.

the sounds you describe are coming from the transfer case, which is further supported by the fact that you hear the murmuring whenever the vehicle is in motion (even with the transmission open). the murmuring noise should be directly tied to vehicle speed if this is the case, in the sense that the sound gets "faster" as you move faster.
 
your description sounds virtually identical to what i hear from my 249 TC in my '98 GC. another confirmation would be to move the quadra-trac drive control lever (which is connected directly to the TC) slightly and you may hear the sound become louder or softer while moving. it is also possible the overdrive is contributing at speeds above 40 mph - to test this, disengage the overdrive while coasting and see if it gets a little quieter. the overdrive has a viscous clutch (like the TC) that get's noisy at high mileage.
 
a noisy TC is common with jeeps, so it's not necessarily something you need to worry about. mine's been getting steadily louder since about 120K, and i now have about 140K. just keep servicing your differentials/TC every 20K and you should be OK. if your TC starts to fail you'll know it . i'll hold off replacing mine until i can no longer hold a conversation inside my truck. but if you have $1500 to throw at it, all the power to you.

#314 of 440 Engine Vibration too 03 4.7 v8 by jeeep

Jan 25, 2009 (7:18 pm)

Hi, I have a engine Vibration too. Seems like it started over the summer. Its a 03 4.7v8 LT with 32 thousand miles on it. I have taken it to the dealer 3 times, 1 at a different dealer . Had the 30,000 tune up done also. Had my tiers rotated and it still dose it. It will even has the engine Vibration sitting still with in park and rebbing it to 1500rpm that's were it really like to vibrate at in that area. I can feel it in the steering wheel and pedal. So I have a love & hate thing with my Jeep, I love it when its parked and hate it when I have to drive it. So I don't know what it could be. The dealer just says it normal, the maint guy said it feels like a Jeep. I think it may be the transition ?? Some times that acts up too, when I shift from R to D it will want to die some times??? Any ideas? It dose more weird thing but i will save that for some other time.
Thanks for any ideas.

I have a 1996 Jeep Grand Cherokee with a new engine in it. Actually the new engine has about 3500 miles on it now. Ever since I replaced it, when I first start it up in the morning and accelerate, I hear a strange gurgling sound coming from beneath the passenger side dash. It sounds like water rushing through a tube or pipe or something?? Did you ever figure this problem out?

top off your coolant system, there isn't enough to stay in the heater core, the "gurgling" you hear is coolant filling the core back up as you accelerate, increasing flow pressure in the coolant system- fairly common for a major engine repair that requires the system to be drained.

#317 of 440 weird noises from dash 2002 grand cherokee overland by morgan051405

Feb 06, 2009 (6:01 pm)

i have a 2002 overland with 55k. once the vehicle has been driving for about 20 min there is a strange sound coming from behind the dash. it is almost like an air switch is having problems. the noise ceases after a while and starts up again. the noise only occurs while the vehicle is on. Any suggestions?

Try turning off the ventilation fan and see whether that makes a difference.
