Jeep - Grandcherokee :: Front Differential Noise - Pitch Increased With Velocity?
Mar 2, 2013
Recent noticed a whirling noise coming from the front of the car. Pitch increased with velocity, but not RPMs. A mechanic diagnosed it as a worn front differential. I have a long highway trip coming up and want to know if this will stress it to its breaking point and I'll be stranded. Also, what should it cost to repair. This mechanic said an overall is $1K. 267K miles on a 2001 Jeep Grand Cherokee with the 4.8L V8 engine. Never had a work done on the front differential.

The caliper/bracket has worn down on the front brakes to the point that I am replacing pads couple of times a year and they vibrate excessively when braking hard like on a hill. on other year years, these parts are separate and bolted together, on the 95 it is one welded piece . I cant seem to find a replacement part, even when trying to order the entire wheel hub assembly it doesn't show/specify if that part is attached. I did find replacements at a junk yard but they too were worn. Is it possible to convert to another year wheel hub assembly?

1995 Jeep Grand Cherokee LTD. This is a 4X4. This Jeep runs great in all other ways, but only when it's hot out--hot enough to create heat on the front suspension, this problem occurs. The CV Joints have ben changed. Short Trips, it will not happen, only after warming up. It's never happened in cold weather. Been Greased. Three mechanics have looked at this and have found no reason for the problem. . .only to say, yep, it's a problem.

Went over a bump on the highway the other day and heard a loud noice as if I was dragging something under the car. I checked but nothing was there. It reminded me of putting a baseball card in your spokes of your bike when you were a kid. It happened twice and the weird thing is that if I put it into reverse and drive about 10ft The problem went away. But something still seems loose and it sounds like it will happen again. I was googling this and it seems like the noise was around where the center differential or drive shaft?

I have a 2005 Jeep Grand Cherokee Laredo V6. I am ready to sell it but I have a problem and the problem only happens when I'm driving it. Every once in awhile..about 7 times a week, when I turn the key it will make a one click noise but not start. It then starts after the 2nd or 3rd try. I have now taken my Jeep to 3 car repair shops. It has never happened with any of them. They have checked the usual suspects: battery, alternator, and starter (I even had a new starter installed just in case) and everything checks out. My latest car repair guy has had it for 3 days and it starts every time. The last time I brought it home 10 minutes after I had cut my car off and got back in to go somewhere, it did it again. There is no consistency when this happens whatsoever.

2004 GC, 6 cyc, 2wd. Had TERRIBLE noise & vibration when braking but problem was intermittent, no codes generated. Everybody suspected ABS problem. New pads, new rotors, new ABS module no luck. Frequency increased but severity decreased. Technician finally experienced one occurrence, identified & replaced a weak steering stabilizer. Problem has surfaced again but not so severe and appears to be increasing in frequency.
My best description is when braking from 45-50 mph, Vibration & noise begins at about 35 mph, increasing in intensity until about 18-20 mph then stops. Seems to me that the transmission downshifts and the noise stops. AMCO suggested a cracked flywheel or loose bolts on the torch converter. Also the engine idles at 1100-1200 rpm on start-up then goes to 850 rpm - will not go lower. Does this sound like a transmission problem? The transmission was rebuilt/replaced at about 94,000 miles and the problem started at about 111,000 miles.

It was running on 7 cylinders and had not been tuned in probably 50,000 miles or more. I recently bought it at auction. Changed spark plugs and 1 coil for the dead cylinder. Rear cylinder on passenger side was not firing. Compression test shows 150 psi that cylinder. Fairly loud mechanical pecking from that area which was isolated with a stethoscope. I suspect a flat cam lobe or broken rocker arm.

I recently began hearing a noise from my car when I change the temperature inside the vehicle. When I adjust my temperature control either direction, hotter or colder, I hear a temporary clicking noise that is pretty loud. It sounds like it is coming from behind the dash. It sounds mechanical and stops after a few seconds. I have a manual temperature dial. This is not a digital display or climate control. This is on a 2005 Jeep Grand Cherokee.

I have a 1998 Gr Cherokee with an automatic tranny. It is slow to shift when cold and the overdrive shifting works reasonably well but I have been told by a reputable mechanic that the tranny needs a new tranny filter at over $1000. My latest check of the tranny fluid and the level and quality indicates both are good. Should I replace the tranny filter?
Also, for the same above vehicle, when I put the vehicle into a moderately hard turn (right and left), the front wheels audibly click and you can feel the click vibration in the steering wheel when happening.

I have a '96 jeep grand charokee Laredo with what I've been told is a bad differential. The bearings and gears are all shot, but can't afford to get a new one. I have taken off the front driveshaft to try and make it drivable again, but it is still making the grinding noise it was before. As well as catching real bad. Just wondering if I need to bother with it, or even attempt anything further.

For the past day and a half, when i start my car there isn't the usual smooth, quiet sound of the engine starting. There's a slight delay, and a whirring noise. When i put the car into gear and accelerate, the noise increases in volume and pitch. I think it might be something with the power steering pump or a belt issue, but I'm not fluent in Car and Driver speak.

A little over a month ago my battery died and I ended up having to get the battery installed one day and the alternator installed the very next day. After the alternator was installed, I started my car up and when I eventually turned the Air conditioner on, it started making a screeching/squealing type noise. I was first told it was the belt needed some lubrication but that didn't work.
I was later told the ac compressor was bad so I had it replaced. The mechanic thought he ordered a bad compressor so he ordered a new one and installed it....it was quiet for about 2 days but then it started squealing again. the sound was not as bad as before through but it was slowly getting worst. I took it back and he then told me the alternator was causing the problem on the ac compressor so I again I had the alternator replaced....no change. He also replaced the belt and no change. at this point we don't know what's causing it?

I have a 1999 Jeep Grand Cherokee that, upon starting in the morning, has a knocking noise coming from the front passenger-side wheel area. It only knocks when the car starts moving, and stops once I get up to 15-20 miles per hour. It ONLY does this when the car is cold. The noise does not occur throughout the day, only when I start it each morning. Is it something to do with the wheel bearing, but that does not seem to be the case.???

I have a 2007 Jeep Grand Cherokee that I absolutely love, but lately a I've been noticing a problem with it gradually getting worse. When I am on my way to work in the morning, and I get on the on ramp to the highway, as I start to accelerate the back end of the car starts to make a rumbling noise. When I look at my gauges the rpm's are going up and down kind of like it doesn't want to shift. The only other time I notice this is when I try to climb a hill on the road or highway. There is no check engine light on. I have had this problem for quite sometime, but just recently noticed it because it has gotten worse. My husband has had a few mechanics drive it, and has asked a few others about it. They either don't know or have a very wide range of things it could be. My friend I work with had a Pontiac Grand Prix. She said that her catalitic converter plugged up and caused her transmission to go out.

I noticed that my Jeep has been making a distinct clapping noise any time the engine is not up to operating temperature. It sounds worst on cold mornings, but becomes quieter as the engine warms up. The noise is RPM dependent, so I'm assuming it has something to do with the engine. The noise is not audible when the engine is idling in park, but quickly shows up as soon as I put the car in gear and add gas. My father and I think that a slightly loose rocker might be the cause of the noise, but we're not sure. A mechanic friend of his told him that our jeep has self adjusting rockers so it can't really be fixed without replacing it. I've never heard of such a thing so I'm having a hard time believing it. The really confusing part is that it only makes noise when the car is in gear and the engine is under stress, making no noise when it's just idling, even when the engine is revved. Since purchasing it 5 years ago, we have been careful to do regular maintenance on our jeep so I'm somewhat surprised by it.

My 1999 jeep grand Cherokee with 170000 miles with a straight line 6 cilinder has a knocking noise coming from the valve cover area. It is only present during a cold start and for about 2 to 3 minutes. Once it starts getting hot it stops. The engine runs fine it has lots of power and I do not have any other issues.

I have a 2009 Jeep Grand Cherokee 4x4 Laredo. For approximately the past 7 months there has been a noise coming from the left rear of the vehicle at speeds above approximately 60 mph. The sound is not metallic in nature, it sounds more like a seat belt flapping against something. The frequency is approximately 2 Hz and is very consistent at highway speeds. The driver can seldom hear it apparently due to interior acoustics, but the someone in the passenger seat or the back seat hears it plainly, over a period of time it is very annoying.
In addition, if you touch the left rear interior side panel (in the cargo area) it seems like you can feel a small vibration that matches the sound. I have had the vehicle inspected by Jeep, they find nothing. I have had the left rear interior panel removed to see if there was a problem with the sound system cable bundle that runs through there, but it was OK. We thought it might be the metal gas tank door vibrating in the wind stream, so we taped the door down, but the sound was not affected. What the source of this sound might be?

2004 Jeep Grand Cherokee V8 4.7 L. Clock from right side of engine immediately after starting engine. Seems to be in rhythm with engine and increases in frequency as I rev. Gradually subsides over first 5 minutes and not audible after that. Recent small leak of transmission fluid, but I'm thinking that has nothing to do with this.

Firstly the truck in question is a 1994 GMC K1500 5 speed 350TBI.
Ok so I'm not sure what is causing the noise I'm hearing. its a humming that I think is coming from the front differential but I'm not sure, maybe it is the transfer case but it certainly feels like its in the front end and my steering does seem affected while in four wheel drive. It only makes the noise while in four wheel drive.
I have one off size tire on the rear end and I'm not sure if the actual tread circumference is the same between the front and rear tires or if any of this would really cause my four wheel drive to act up. I am planning on putting a new set of matched tires on it soon, so if they are the cause of the problem then that's good news.

I replaced the timing belt an waterpump at 262,000 miles and ever since the engine makes a loud low pitch noise that varies in pitch depending on the engine speed. I replaced the alternator and it didn't work. I don't know if the power steering pump, a/c compressor or something else is making this awful sound.
