GMC - K1500 :: Humming Noise Coming From Front Differential
Dec 28, 2013
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 have a whirling or spinning noise coming from front differential at speeds above 30 mph. The noise stops when I release the accelerator? From what I read maybe the bearings.

I have these in 225/40R-18 on VW Goal rims (MkVI GTi). Last month I hit a nice size pot hole and put a very small bend in the outer lip of the right front rim. No mark on the rim, so the tire took the hit. Had a peak inside and the tire was bruised pretty good. Around this same time I noticed a faint humming that seemed to be coming from the front. Figured an inner ply shifted so I replaced that single tire (10,000 on the others).
So the humming is still there and getting a little louder. I've rotated a couple times but the sound is the same. Non-distinct location; seems like it could be coming from all 4 corners.

we've had a bunch of snow this week and I've been driving around with my hubs locked in. today I noticed when I was slowing down to pull into my driveway I could hear a slight squeaking sound(sounded like a squeaky belt) coming from the front.
I verified it was coming from underneath the truck behind the engine compartment so I unlocked the hubs and went for a drive, the sound was gone. I crawled underneath and turned the front driveshaft by hand and I could hear a slight rubbing sound at the back of the pinion. The bearing doesn't have any play in and there are no leaks. What is going on? Could the bearing be starting to fail or could the rubber seal around the pinion have some grit in it causing the noise?

I have a 2002 Silverado 1500 Z-71. In 4 wheel drive, I can hear a humming/rubbing noise from the front end. Not real loud, but enough to get my attention. It happens at around 25 mph, and just as I'm coming to a stop. This is on the street.....going straight, not while turning. I only engage the 4 HI during street driving on a straight line drive just to "exercise" the gears and transfer case. I don't notice it on the dirt 'cause of trial noise levels. All fluid levels are normal in transfer case and axles. How much noise is normal during 4 wheel drive operations?

Ok at 40 mph and above I have a loud humming noise coming from my left front wheel. I replaced my rotor and pads due to normal wear. I also replaced the bearing. No fix. Tires were rotated a month ago. Could it be my CV joint? The boots are fine.

As I begin to accelerate a humming sound from the front of the car begins. The noise becomes more pronounced the faster I go. No additional noise is made when I brake or turn, nor does it appear to be any noise when I went in reverse. I made a 180 mile trip on Sunday with no problems, although I did travel at closer to 55mph than 65. The car has 170,000 miles on it and has had most of its scheduled maintenance performed.

2001 f150 xl with 151800 miles 5.4l had it for a few years now I get a humming type groaning coming from up front. only when in 4x4 and only at lets say 25 mph to 45 mph .seems to be worse when slowing down especially the slower you get then around 20 or 25 its gone. it is still quite noticeable on acceleration and after 45 its gone. Truck has always been a little noise while in 4x4 weather it was an issue that had already started or if that's how it is. This is my first 4x4 truck.

I purchased my first truck 2 weeks ago private sale a 2001 Explorer Sport Trac 4v4 4.0L. I noticed it had small leaks coming from transmission and front differential gaskets (the diff is silicone) but the oil levels remain fine. Within days I heard a loud hum coming from the engine for 10 seconds then immediately after i was slowing down for a speed bump and my truck tried to stall and since that point it was riding very rough at low speed/idle and sometimes giving it gas seemed to just kill it. Next day a check engine light comes on and I get it checked It was Bank 1 running lean and B1155 (Output shaft speed signal) which concerned me from what I found it is located by the transmission oil filter which has the leak.
A few more days later I broke down on the side of the road, the alternator had died and killed the battery, I replaced the alternator and belt, replaced the 6 spark plugs, 3 of which i removed way to easily with my hands and all 6 had an incorrect gap. Initially the car was still rough but now with the new plugs it is drivable but still a little weird on startup and idle and a little bit of the shakes around 60-65mph and seems to be over actively shifting soon as i let off the gas even a little bit. Today I had the check engine light assessed again, now Bank 1 and Bank 2 are lean, still have the B1155 as well as a new C1676 (Battery pack voltage out of range) which light research said it could be ABS module or it could be a false code from being jumped days prior and that code wont clear on its own.

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?

The sound is coming from the front passenger side. The noise gets louder the faster I go, put in neutal and noise still there press brake noise there turn wheel no change in pitch. Jacked it up and there's no play in wheel. Just changed both front wheel bearings 6 months ago.
Just changes all brakes today and got all new tires today. I'm thinking maybe the differential bearing but not sure and if so how to change it. I travel from Mississippi to Baton Rouge, LA everyday for work, about 240 miles round trip. What would happen if a bearing went out while driving 70 mph on interstate.

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.

I have a 2002 f150 5.4 with 3.55 limited slip... For months now every time I hit a bump with the front right side there is a loud bang (sounds like a wore out bushing), and if I am driving slow at an idle you can here a thump every time the wheel goes around. And when I turn all the way it sounds more like a grinding sound.... The noise is getting very bad, what it is. I am very mechanically inclined but cannot figure it out.
Everything in the front end seem tight. When I lay under it if I get someone to spin te wheel the thump sound sounds like its in the front dif, kinda echoes through the front drive shaft but u joints seem good. I really think it's in the dif, and I'm hoping the banging noise I hear when I hit bumps is the same problem as the noise when the wheels go around....

I have a 2005 prius that's not starting with the red exclamation . I had took it to the dealership before and they told me it was the big battery since I had the battery under warranty I just had it replaced and the 12v battery myself . Now when I went to start the car everything started fine car was running like 10 mins the heat never got warm then it shut off red exclamation popped. I turned off an on then I heard a humming kinda sounding pitch coming from front of car that got higher and higher then shut the car off and red triangle pops up and that's what it's doing now.

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?

For starters I have a 1999 F-250 5.4l changed all 4 ball joints about 15,000 miles ago. I have been hearing a grinding noise coming from the front end for the last month only when I turn left and at slow speeds. I was servicing the TC so I threw it in 4 wheel to check it and it wouldn't engage until I started moving. When it did engage it was a bad grinding/ clunking sound coming from maybe the differential.

So I've got an odd noise coming from my engine, sounds like a hum or quiet whine. Almost like the whine of a supercharger.
The noise does get louder when the rpm's increase. So wondering if had the tensioner pulley fail, if there were any noises associated with it prior to it failing?

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've owned this 1987 BMW since February, and after immense and expensive repairs, it became roadworthy. Recently there has been moderately high pitched hum coming from the Drivers side, approximately under the rear door area of the car. It seems to be coming from a part of the exhaust system(?). This part is white, vibrates, and is cylindrical in appearance.
The car only had one previous owner. He kept all record of the car over the year, so I know of no wrecks, repairs to the exhaust, and/or body work done to that area.
It is a menacing sound but doesn't seem to be affecting anything, and it only happens occasionally. I have noticed it mostly when idling, but it still occurs some when in first and second gear.
How to identify this part? I've looked through a few diagrams, but I am unsure. I need to know the importance of this hum, and whether I should seek a mechanic.
