Alero :: 2003 - Loud Humming Sound At 40 MPH+?
Oct 14, 2010
Our car is a 2003 2.2L 4 Door. 132,000 miles.
About 3 days ago it started doing this thing where once we hit somewhere between 30-40 mph, it started making a low pitch humming sound. At 40 MPH+ it is very loud. To me it sounds like an airplane, I don't know how else to explain it. There is no shaking, though sometimes I can almost feel the vibration from the humming at my feet. My husband says that the higher the RPM's, the louder and slightly higher pitched the sound is. If we go below 30 MPH it stops.
We were a little late on our oil change and I assumed that was it, but got it changed today and it's still doing it. Other than that, about 2 and a half weeks ago, our rear driver side tire went flat. My husband was in the middle of no where on the way home from work so he used Slime and that fixed it (never went to get it repaired because we didn't have the time and it didn't go flat again).
Could it be that the tires are not balanced correctly because of that, and it is causing the humming?
Also, this may be completely unrelated but: The only other problem we have had/still have with the car is that about 2 years ago we drove from Texas to Nevada, and at one of our stops the coolant dumped out (did not overheat/no other issues). Took it to 2 different shops and they couldn't find anything wrong with it. Drove fine until 6 months ago driving from Nevada to New Mexico, it did it again, but this time it also overheated. The mechanic said it was the water pump. Replacing the water pump (which is expensive!) did not fix it, so without consulting us they also changed the thermostat. Charged us for both, told us it was fixed, and about 2 month ago it did it again, but did not overheat/no other issues again. Hasn't done it since...seems it only happens on long drives. Anyway, I don't think it's related, but I thought I'd mention 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.

My car has an unsettling noise. It is a loud clunk in the front end that can be felt. It only happens when turning right (just past where the wheels are aligned) when going forward. I believe it also happens when backing out of a spot to the left. It is only one solid clunk. This clunk isn't always loud, and can be subtle. If I do a figure eight, the clunk will be the loudest with the first wheel turn to the right, then will either get quieter or disappear all together. Let the car sit for a while, and the first turn will be the loudest.
Things that have been tried:Full Strut/shock assembly replacement on both sides of the front suspension.Sway bar link replacement on both sides.Both front control arms, complete with ball joints and bushings have been replaced.
Possibilities I haven't changed or on the list to examine/replace:
-Sway bar bushings
-Wheel bearings
-CV Joints
-Engine mounts
-Tie rod ends
What should I be looking at first? Is there something I am missing? It's been to the mechanics a few times. For a week after the control arms and sway bar links were replaced it was ok, or dull enough not to hear. Now it's back as loud as before.

I am hearing this buzzing sound in my trunk its really loud for ex: those annoying sounds people played as kids that people over "18" cant hear...back to the point its by my rear left tail light inside that area where all the wiring is also kinda hear it where the spare tire is all my lights work I unplugged the light and it still made the sound! It only does it when the car is running. Car is stock aside that it has no radio and the cd changer in the area that noise is coming from idk if its because a few wires that connect to the cd changer or what ever it is are unplugged but its coming from that area of the car its really high pitch and annoying.

This is a question about a Subaru Outback, but probably pertains to many other cars as well. I have a 2006 Subaru Outback with 112K miles. I bought new tires for it in May 2012, and in September 2013 I started to notice a low humming/buzzing sound while driving. I looked online and came up with 2 options - either the wheel bearings or the tires. Because the sound changed pitch depending on the road surface, I thought it must be the tires. I took it in for an oil change and had the mechanics check the bearings. They said the bearings were fine, but the tires were cupping and feathering badly because I hadn't rotated them, and that was the source of the noise.
I had them rotate the tires and do an alignment and went on my way. The sound slowly got worse - it peaks at ~65 MPH and then changes pitch above 70 MPH and is not so bothersome - and I started to lose gas mileage ( 4-5 MPG). On Dec. 30, 2013 I took it in for the next oil change and bought brand new tires - Bridgestone Turanza Serenity designed for quietness - and had them do an alignment, and drove away only to find that the noise is still there and I still have lousy gas mileage.
My next thoughts were the transmission or the catalytic converter, but since the noise doesn't change when I take my foot off the gas or put it in neutral I don't think it is either one of those. The alignment showed that the Caster on both front tires is off, but since both tires are off by roughly equal amounts I was told that this is not something to worry about. I do occasionally notice some vibration while driving or while idling, but it is intermittent and I don't think it has anything to do with the noise.

When I am in reverse sometimes the left rear makes a loud humming sound like the brakes are rubbing or something. What do you think this is???

After I took my Ford Focus 2011 to the dealership for a free oil change I noticed a subtle, low hum coming from the car when I hit speeds past 40mph. At first it sounded like the engine of a louder car driving near me so it took me a couple days to realize that it was actually my car making the noise. I intended to bring the car right back to the dealership to complain about this but I kept getting preoccupied with my studies for my summer courses. It's been roughly 3 weeks now and the low hum has gotten a lot louder now and can be heard over music.
The noise begins when I approach 40mph. The noise is probably at its loudest at speeds of 40mph-70mph. The noise is made even when I am not stepping on the accelerator or using the breaks. I haven't tried putting the car in neutral at those speeds. What might be causing that noise? Although I don't really trust the dealership since my car seems to manifest a new problem after each visit.

So there is a loud humming sound as I would describe, coming from the passenger side glove box when I turn my fan to run at high...

I bought a used 2010 corolla and notice a loud humming sound at the rear when it reaches 40 mph. I figured it was the rear hub bearing assembly. I already bought a pair of Beck/Arnley 051-6262 hub assembly. I found two threads here about the removal/installation but did not say the torque of the 4 bolts behind the hub assembly. I read on the Toyota Manual that it is 74 ft-lbs. Do you think that this is too tight for a 10 mm back plate. The wheel/rims bolt torque is 76 ft-lbs but the nut is about an inch length. It is almost the same torque for an inch nut compared to 10 mm back plate. Is 74 ft-lbs right especially for an aftermarket beck/arnley brand? On the Toyota Manual, the 2003-2008 Corolla 4 bolt torque is 45 ft-lbs. The 2010 is 74 ft-lbs???

I took my car in to get this checked out, but they say they can't hear it.
Sometimes when I turn my car on right after I turn it on, there's a loud humming sound like a compressor or something is kicking on and it's not fully engaging. And it only makes the sound for maybe 3-5 secs. Sometimes it won't happen when I turn the car on, but when I'm driving and I let off the gas and go to touch the brakes, it'll start.
The best I can describe it is a 'hum'...but it's loud, and I can feel it as if it's near the gas pedal right behind the firewall.
Dealer thought maybe it was the ABS switch testing itself..but they could never reproduce....I got in after they replaced my rims and checked it...and it did it 4 times when I started it, then turned it off. He came out to check, and it was almost as if you couldnt hear it outside of the car.
So, what the sound might be...I can't reproduce it anytime I'm there. Figures...... but I hear it almost daily. He put some foam tape on the firewall behind the gas lines saying the 'pulsing' from them might be doing it...but it did it again this morning.

I have a 2000 Olds Alero 3.4L. The car has been making a "humming" noise near the front end. It sounds a lot like the noise you hear when driving on rough road. It happens no matter what gear the automatic transmission is in. It changes sound with speed (most prevalent at 40 MPH). The sound also changes when I turn the wheel - it is worse when I turn left going down the highway and the noise is less when I turn right. I have replaced the driver side wheel bearing, the drivers side dive axel (I noticed the CV boot was leaking), none of this worked. It sounds like it is on the drivers side so I have not messed with the passenger side. (CV joints look fine on the passenger side). I put the car on a lift and ran through the gears - there is a vibration (car shakes) as the tires speed up - but I can't tell if it is a tire or something else. I need to know what this might be - transmission? -Tire? -Passenger Hub?

Problem that developed after our 03 xle got whacked by a Harley in the right front wheel. The repair shop changed out the spindle and wheel but we got it back with a loud humming noise over 40 mph. The shop said it was the axle shaft bearing and not related. I argued and the insurance company reluctantly agreed to replace the shaft,bearing, and housing. Got the car back and again, the same humming only less faint and obviously coming from the trans. Everyone is dodging responsibility and it looks like we are left to sort things out on our own. Figures. This car road perfectly prior to the accident. I can't find any online diagrams of the trans to see what the shaft fits into. Supposedly the shop is holding on to the old shaft, I was going to go and look at the end splines, I believe that's what it has.

First off I have a 1997 F-150 4.6 with 205,000 miles on it.. stock engine and tranny. It's been a great truck and never given me any major problems. But recently something under the hood (wish i could be more specific) makes a really loud HUMMING noise (almost sound like a trumpet). For example- say im driving on the highway and i let off the gas, this humming noise will appear and it is very loud, but right when i give the engine some gas the humming goes away.
Or also when I am driving through town, when i come to a stop light, let off the gas to apply the breaks, this humming noise will come about. what i have to do is stick the truck in neutral and give it a big rev (which i do like hearing my exhaust so it isn't always annoying) and then it stops. note though, it doesnt happen every single time i let off the gas, however it is pretty frequent.
do yall think this is in the air intake system? thatd be my only guess because when i rev the engine it quits, but one thing is it sounds like it comes more from the passenger side of the truck, and it seems to occur more often when the temperature outside is cold. im completely stumped by this one, ive never heard anything like it.

First of my truck is an 03, xlt 4.6 5-speed with 82,000 miles. Almost always when i come to a stop i can hear a faint humming that is coming from the engine compartment. There is no pattern or set way that this humming happens, it just comes and goes when at idle. As soon as you put load on the motor it will go away. I got under the hood today and fired it up, nothing, gave it just a little throttle and sure enough here is this odd humming. It is coming from in the air intake. Also while i was under there i noticed that the cable that is right next to the throttle cable is very loose, i am not sure what this cable goes to or if this could be part of my problem

I have an 03 Exp 4x4 Limited with 4.6L V8 with 167K on the clock. I'm getting a kind of humming rotating sound out of the front end when moving. The frequency definitely goes with the wheel rotation speed and the noise is the same with the trans engaged and when coasting in neutral. The noise is present at all speeds but becomes more of a humming sound as the speed increases at highway speed.
I've had both front wheel bearing hubs replaced (they were completely shot), brake pads and rotors replaced, and just had new tires. The rotating sound is still there though. What else is there that could be the cause? Is there another set of bearings somewhere in the front end?

Alright so I'm having a problem with my 2003 Ford Explorer. I've recently noticed that when I get to above 40 mph, if my steering wheel is straight, I hear a loud kind of grinding or humming sound coming from my left driver side front. If I am going about 65 mph, it gets even louder and if I crank the steering wheel to the left, that's when it really gets noisy but as soon as I crank it to the right, the problems gone. When I do hear the hummin sound, I can feel it in the steering wheel. I have replaced al of the tires and it didn't work. Also, the car slightly pulls me to the right.

I have a 2003 F150 manual 4WD with 4.6L engine and 165000 miles. When i am driving i feel a vibration in the steering wheel and on floor board that intensifies when i press the accelerator. I do hear an irregular humming that sounds like it is coming from the driver side front. I checked the wheel for any play but it was very tight. i check tie rod ends, ball joints no play. i recently changed both u-joints on the rear shaft and the bearing hub on the passenger side front. Also, the steering feels a little 'wobbly' when i make sharp turns. it almost feels like it is giving. What else should i check?

On my way home from work the other day my 2000 7.3l started making a humming sound while driving. I noticed that it was shifting harder and it began to slam into gear when I would take off from a stop. By the time I pulled into the driveway I had to be half way into the pedal to keep it moving. I shifted into reverse and it clunked loudly and didn't want to back up. I don't know much about transmissions but I'm thinking that it's probably shot. I'm hoping that it's something other than a complete rebuild but doubtful.

My daughter has a 2003 Oldsmobile Alero with 120,000 miles on it. She tells me it is making a squealing sound which I suspect is a loose serpentine belt. But I'm 18 hours away and can't diagnose it for her.

I have noticed a loud humming sound coming from the truck when I have the AC on. Also you can feel the vibration as well. I turn off the AC and it goes away. All this happens on an infrequent behavior but does happen daily. what gives?

I have a problem with my 1986 Toyota 4X4 pickup for over four years now,the problem is a noise from the front end that occurs when hubs are in Locked position a loud humming that comes and goes, I can hit the brakes hard and it goes away for a few seconds, I can hit a bump and it goes away for a few seconds, I can take a sharp turn and it goes away for a few seconds. This woowoowoo or hum only happens when the hubs are locked not when they are in the free position, I cannot shift in 4wd and make it go away for a few seconds, the noise gets worse the faster I go, it also gets worse the colder the weather is. I have replaced the axles twice and the front diff once and still has a noise, I have checked the wheel bearings for play and they are fine, I have repacked the hubs with fresh grease, the sound, sounds like metal to metal friction.
