B6 manual, after 20k miles with Dunlop Sport Maxx 235-40-18 tires (still pleny of tread left, even on fronts) a moderately loud humming noise has developed, loudest at 35 mph but even heard at 10mph, with an irritating resonance of subwoofer-type. Noise changes somewhat with road surface, but not much. Not related to engine speed, gearbox, or radio. My next step will be to swap wheels.
For now, any thoughts as to the cause?
I installed a CAI (CTS Motorsports) and I'm hearing some sort of resonating humming while driving. I also installed a 3'' turbo back exhaust (SPM) and did APR stage 2 tuning. I did not do everything at once, the CAI was installed 3 weeks prior to any other install on my car. I've been hearing that annoying hum ever since I installed the CAI. The humming doesn't happen when drive normally, shift and slowly increase the throttle, but when I stomp on the gas I hear it every gear shift around 3000 to 5000 rpm. When I mash on the gas and shift, it hums only for a short period of time until i shift again. I don't think its a high speed hum issue. I can easily do 120 and not hear a thing, but when i rev at high rpm's I hear that resonating hum.

View 4 RepliesMy 2011 malibu has approx. 20,000 miles, it makes a loud humming noise that is very annoying, can't even hear someone talking and must turn up the radio. It gets much worse when you get up to 55mph and above. I thought it might be the tires but they look good, but could it still be the tires?
View 5 RepliesI thought it was the tired due to the cold weather. But now it is warmer the noise is still there. Bareknuckes previously mentioned wheel bearings as a potential problem. The car is driving (sound-wise) like I have some huge mud-bogger tires on or like crossing a cattle-guard continuously. so loud (in the cabin) that sometime I forget to shift because I hear the humming rather than the engine.
View 2 RepliesProblem 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.
View 2 Replies2005 Jetta. The car makes a loud deep humming noise once I hit about 75mph, and goes away once I get to about 82 or so. I've taken it out of gear and matched the rpm I get at those speeds, and I don't hear the noise at all. It's only when I'm in gear. What this could be?
View 4 RepliesA loud humming (sounds like a compressor). I can place the car in neutral, the engine revs up, and humming will stop. I have to repeat this action for the first 30-45 minutes from start of drive time.

View 5 RepliesFirst 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.
2007 GS 350. In the past 6 months i have changed my FRONT brake pads with two different pair. First was a generic pad(REMOVED), and did some research then went for Akebono(CURRENTLY) brake pads 2-months noise-free and now back to braking noise dilemma.
Issues:
-In the morning, first 3-5 pressed brakes makes loud(REALLY LOUD!) humming noise then goes away. Feels like the brakes are rusty but it continually does it everyday. I just got the car serviced so assuming all my fluids are filled.
-Randomly, on a fully stopped brake i hear a whistle noise from the front brake. NOT as loud described above.
-I noticed the noise happened the most on HOT weather, and occasionally on COLD weather.
Longo Lexus advice me to buy an OEM brake pads and should resolve this problem. I'm also thinking of just getting it done at the dealership and pay that extra cash plus warranty.
Car was overheating for a long time. Went to start it and wouldn't start. Its been sitting for a while so I replaced the battery and now when the battery is connected its making a loud humming noise. And still no start. It turns over and sounds like its trying to start just won't start.
View 3 Replies2005 jetta. On the highway when I hit about 75mph I hear this loud humming coming from either the engine or the exhaust, I'm not sure. It disappears immediately once I cross about 82mph. What could this be? Why such a specific range?
View 2 RepliesI am trying to diagnose a sound that is coming from my 2001 Camry 2.2L. When I accelerate there is a load humming noise coming from the engine. It happens at all speeds and only when I accelerate.
View 6 Replies1999 ford expedition 5.4L ....I have been hearing a loudish (I can hear it in the cab) humming noise coming from the engine bay. I don't hear it when the truck is cold (1 to 5 minutes after starting), seems to get louder at it its peak (the more I drive). When i open the hood, the humming is coming from the intake. I am a pretty handy guy, just at my witts end right now....not sure, but I was thinking brake booster?
View 3 RepliesI have a 2006 lexus es 330 that just turned over 90,000 miles. My dad and I have done the regular maintenance on it so far but this weekend after a 3 hour drive, I turned the car back on and a loud whirring/humming/whining noise was coming from the engine. It gets slightly louder with acceleration, but I can barely hear it once I've picked up speed (but it's still there.) It still happens when I am in neutral. It sounds like it is coming from the passenger side of the engine. Close to the power steering pump area, but the power steering fluid is full (although it is a very dark/black color and has a slight smell...not sure if this is normal.) I'm not having any trouble or hesitation while steering. The rack is operating smoothly and it is not leaking. I plan on taking it into the shop but wanted to go in educated.
View 3 RepliesI have a 2005 Hyundai Elantra that makes a RRrrrRRRrRRR noise when turning corners - only to the right. It's not a screeching or scraping noise... more of a loud whirring or humming. One note- back left tire was removed and repaired shortly before this began - could that relate?

Getting a pretty loud "whirring" or humming noise from under the car while driving 30+ mph. It seems like a wheel bearing noise, but coming from directly under the center console area. My thoughts are either the driveshaft center support or the transfer case, I can't find much on it though.
1996 Exp 4.0L OHV ... Wife drove it the other day, said made loud humming noise, then engine stalled. Drove it this am, did it to me too while idling in D with foot on brake... humms for about 1 min, and then stalls the engine... If I rev the engine, was still doing it... but came and went when I was driving then till I got her home...
I know there is a black plastic cap that makes a similar noise but not as loud, this seems like something else... and the fact it stalled the truck is bothersome... it started up then fine, but still. The only thing that is the same as when wife had it, is that both of these days are like under 10 degrees outside... So, me thinks MAP? or something else that doesn't like these REALLY cold temps? or??
As I accelerate, there is a humming noise that comes from the transmission area of the car. It does not make the noise when I am in idle, nor if i put the transmission in neutral and rev the engine.
When driving slow the noise is very subtle. As I accelerate faster the noise gets louder. The noise becomes the loudest at 60 mph. Above 60 it seems to calm down some. The noise is like a constant, deep humming sound. The noise gets softer as I slow down and then is gone when at idle again. To me it seems related to the speed of the tire or the CV half shafts turning or something rubbing in the transmission as the car goes faster. However the sound doesn't change when the transmission shifts. It stays constant and only gets louder as I go faster and then softer as I slow down.
While driving and turning hard to the left the sounds almost disappears until the car straightens out again. I have replaced the struts on all four wheels and this seems to only have caused the sound to get louder. I have also inspected the CV joints. There doesn't seem to be any cracks or signs of wear to all 4 joints. And I repacked the bearings.
The only other things I can think of is the cv half shafts are actually bad and need to be replaced. Or the motor mounts are not aligned/worn out and need to be replaced. Or the kickdown band and low reverse band on the transmission need to be readjusted. Or the transmission is has a problem (however it doesn't slip when driving).
I bought my 2011 Sonata with 27k miles on it. After a while (few months) I noticed on occasion when turning I would get a screeching/squeal noise from the front tires. Only happened during certain turns (U turns I noticed where higher chance of happening).
I rotated the tires (Front to the rear, Rear to the front), and then there was a loud humming noise. I got it checked with the dealer and they confirmed tires were cupping (uneven treadwear right?) . So now its been 10,000 miles and the noise is the same. I just got an alignment done and there has been not much of a change.
So, other than getting new tires, should I get the tires balanced? Or just rotate them once more so that the rear return to the front again? Will I have to get another alignment done?
