Chevrolet - Suburban :: 2002 - Faint Humming Noise Coming From The Rear
Mar 1, 2011
I have a 2002 suburban . I have a humming noise coming from the rear . It starts at 45mph and then goes away at 47mph. I hear it again between 60-65 mph then goes away . This is a faint sound . When pulling a trailer the sound is much more noticeable and more constant from 55-64 mph . When I let off the gas the sound is still there and fades as the truck slows. Am I dealing with a bad tire ( I plan to rotate them to see if that is the cause ) or a wheel or axle bearing ? To note I replaced the front wheel hub/bearings just about a year ago .

Noticed this during a recent trip halfway cross country. It did POUR for part of the trip, but I didn't notice the wetness until a few days after we were at our destination. Further, none of our luggage etc was wet, so I don't suspect a leak in the rubber gaskets along the window. We did have the A/C running constantly while in 90° heat. I checked underneath the car; saw no obvious signs of rust on the underside. I did see a hose and some type of contraption on the passenger side rear, above the muffler - it was dripping water. Is this part of the A/C system, and could it be the cause of dampness in the carpet?

So today while driving, on pavement, I noticed a low humming coming from my right front tire, looked under the car, everything looked fine, the boot ect. The hum starts at about 25mph and speeds up consistently w/ my driving speed. The truck itself is riding just fine, normal, no issues, but the humming almost seems to have gotten more noticeable throughout today. What could it be? How do I go about diagnosing it?

OK so - I had the rear axle bearings replaced, but I'm still hearing a rotational scraping noise while moving (whether gas is applied or not, or whether braking is applied). Gets slightly louder the faster I go. But when I turn, the noise goes away. It's hard to pinpoint where the noise is coming from. My wife swears it's in the front; to me it sounds like it's in the middle (so it would be being transmitted from the source).
I took it back to our mechanic, but he can't hear it very well - he admits that his hearing is not what it used to be (he's in his 70s). Only thing he hears is "gear noise in the rear"... meaning he'd have to replace the differential in the back which would be prohibitively expensive and not worth it. He said I should come back in a couple weeks when his younger employee will be back so he can listen for it.

I recently hit a pothole and damaged one of my custom wheels to the point it was dangerous to drive on, I could not find a matching wheel for the car (2007 Chevy HHR) and had to drive on the donut spare for about three days, I put the spare on the rear passenger side, So for about three days I was driving with an 18" rim on one side and a donut spare on the other. I noticed a humming sound when I get to 40 mph. I thought it was just the sound of the tread on the spare, But I have since bought new rims and tires and the humming sound is still there. Again, I only hear it when I get to about 40 MPH, below that, no sound at all. The car seems to shift smoothly. Could driving on two different tires on the rear end have screwed up my differential?

2003 Chevy suburban, 115K miles, accelerating I hear a squeal/groan/clicking noise coming from right front of engine. Did not happen this winter, started again in spring. Loses power if stay on accelerator. If let off and then reapply, it will momentarily go away. Appears to be only when air conditioning on. Bad AC or just the pulley?

The last two mornings I have gone into my garage and have heard a faint "buzzing" noise that seems to be coming from the rear of 2013 RX350. Given the location of the noise, my first inclination was that it was possibly the fuel pump running a cycle for some reason. But when I heard it for the second day in a row, I figured it would be wise to ask if this is normal or something I should take up with the dealer?

There is a humming noise coming from the right rear of my R, I'm going to guess that it is the furl pump running? If not I don't know what it could be, or if usually that loud...
Second, I was thinking of getting adjustable rear control arms. I was going to get just one set, to adjust the camber to 0.0 instead of the -1 or so that they usually ride.
Third, I was also contemplating getting upgraded motor, trans, and dogbone mount. I was told it would cut down on transmission noise while letting off the gas pedal whence driving.

I have a '98 Suburban 4WD, last week I started hearing a clicking noise when I go in reverse. Sounds like it is coming from the rear axle area. I don't hear the sound when going forward.

I have a noise that has been driving me crazy for a week now. After some investigation I have discounted a few things. To sum up the noise, it seems to be coming from under the vehicle, maybe the passenger rear. It sounds kinda like a jack hammer and it is loud. People on the street can hear it well! There is no consistency in it. I do not here it standing still and it only appears when I am driving. The speed does not matter.
While driving, it will come and go, it will last from 5 seconds to up to 30 seconds. While driving along, it starts, then stops abruptly without dying down. The speed of the "knocking" will follow the speed of the vehicle. If Im going slow (20 mph) it will knock at a slower pace, thus going 65, it is 2 a second. There is nothing loose, I have ruled that out.
Although it does sound like something loose and hitting. I can feel it slightly on the floorboard under the pedals and passenger side. I have to believe it is the rear u-joint? but that was replaced 2 years ago, and I have never heard of a u-joint making this noise.

I have a 2011 Sonata Limited 2.0t. I get a humming noise that starts out faint but gets very loud. This happens with the ac on and while coming to a stop or while stopped.

I have a '98 Buick LeSabre, 112,000 miles and it's white. When I put the ignition key in and turn it without starting it completely I get a humming noise coming from the rear of the car. It lasts about 5 seconds and stops. When I start the car it begins again and continues all the time I'm driving. A friend suggested it might be the fuel pump.

Checking my garage before going to bed last night and hear motorized humming coming from rear of the GX. I slide underneath and it seems to be coming from the spare tire area. I started the engine, then shut it off and the noise went away. The noise reminded me of the air suspension pump on my old Denali, but my Gx has the standard suspension.

I love the car, but had a few small gripes, including ride firmness and road noise. Well, the ride firmness has definitely calmed down a great deal over the first 3500 miles to now I find it has a perfect balance of handling vs. comfort. It's firm, but the bumps are not as jarring as those first 500 miles or so. I'm very happy with it.
The 2nd issue I hd/have, is road noise... or rather... I think... suspension noise. It's a faint droning/humming sound that I think comes mostly from the rear. You can start hearing it at 20-30mph on all but the smoothest of roads. The noise seems to be *in addition* to the very, very minimal tire noise I hear from the very nice stock Michelins. The harsher the road, the louder the noise of course.
My guess (and it's only a guess?) is that the metal bushing ('pillow ball') in the rear along with the other firmer suspension parts are the primary cause of this noise.
So I have tried a couple of things to try and counteract this noise:
1) Put D'amplifier Pro in the trunk - Got down the bare metal and put the stuff all of the place back there... Above the wheel wells also.
This did not stop the noise I hear.
2) I then put some sound deadening foam mats above both rear wheel wells.
This did not work.
The strange thing is that this noise is pretty faint, but unmistakable... however if I move my head forward (say, right in line with the steering wheel) 2 feet.... I barely hear it. But when I move back to the normal driving position, there it is.

2002 5.4L... I have a humming noise that comes from my engine and wanted to see if any of yall knew anything about it. I sounds like it's on the other side on the driver side firewall near the brake booster. Once the engine runs for a bit it tends to start then. It'll start to hum then ill tap the gas to get the RPMs up a bit then its gone for couple miles then its right back on.

ok so i noticed recently that there was this humming noise coming the rear right passenger side everytime i accelerated up to 30mph. the noise would get louder the faster i go. i got it checked by a shop and they told me that it had something to do with my wheel bearing. my car is lowered on coil covers and I have negative camber on my wheels. Why its making this humming noise or if its because i never got my alignments. I am thinking of throwing my stock suspension back in and letting the dealership deal with it since my car is still under warranty.

2002, Chevy, Suburban 1500, 4wd, 5.3L engine, 210,000 miles. Mass airflow sensor and both O2 sensors replaced last year in an effort to fix this problem. Original problem surfaced when the vehicle was shut down or running uphill and had about 1/2 tank of gas in hot weather. If stopped, the vehicle would not start until it had cooled down. Sometimes getting it onto level ground would be enough to get it running again. ( This accomplished by turning on the key and allowing the vehicle to roll back out of the parking place. ) If running down the road, getting to level ground after the stall, pulling to the shoulder and cooling the engine/waiting a few minutes and restarting the vehicle would work. This was before the above mentioned repairs.
Last weekend in 60 degree weather I was driving back from northern Michigan and as I headed up hill at 75 mph with the tank at 1/2 the vehicle did a high speed stall on me. Symptoms were: RPM showed 2000, but pushing down on the gas actually dropped the RPM no matter how feather-footed I was. This was tried several times. I turned on the 4 ways and moved toward the shoulder and at 50 mph finally got the thing to restart. The rest of the trip home was uneventful.
I had a 2001 Suburban with the same specs which did this same thing until a factory recall that got me a new fuel pump. I asked about the recall the last time my truck was in for service and they said it does not fall within the serial numbers for that recall. Fuel filter replaced about 9 months ago. Co-incidentally but not necessarily related is that my battery with less than 3 years of a 7 year warranty was draining itself in less than 2 days this last winter.

One side of my rear defogger wire has detached from the window. It detached right at the metal clip and window. I will not solder (due to possibly breaking the window). Have tried all kind of epoxies & bonding agents - will not work.

I think I'm becoming an automotive hypochondriac ever since I started owning this car...I was sitting at a light the other day and all of sudden I heard a faint sound coming from what seemed to be the passenger side rear of the car. It sounded like a ticking clock or a heart beat...it was some what faint, but still noticeable. It is intermittent though and has no particulars when it happens and seems to go away when I begin to drive off... Fuel pump? Gremlins?

I have a 2007 Chevrolet Cobalt with 26700 miles on it and I have recently started hear some odd rattling noises from the back right tire area and I have looked under the car to make sure that there was not anything loose under there and I didn't see anything. The tires on getting pretty worn out and I have order a whole new set, but I am still very worried about that noise.

2002 Chevy Tahoe Z71 ... When I first turn my car on in the morning (or after an extended period of time - i.e. the car has completely cooled down) it makes a clicking / ticking noise that appears to be coming from the engine area. It lasts approximately 10 - 12 seconds and then simply goes away. This happens consistently. I recently had it serviced end-to-end: belts, plugs, total tune-up etc.
