Prius (2004-09) :: Low Pitched Roar Or Whine Coming From The Front

About 3-4 months ago, I noticed a low-pitched "roar" or whine coming from the front of my 07, especially at 35mph and above. The pitch of the sound gets higher the faster I go, but its never a high-pitched squeal or anything, just a roaring whine that has gotten somewhat more noticeable as time has gone on. 184,500 miles on the car, Goodyear Assurance tires that will probably need to be replaced fairly soon but are certainly not bald, reasonable tread left. I bought the car with just under 160K, I've put about 25K miles on the tires, but don't know the car mileage when the tires were originally installed.

I had the tires rotated during an oil change about 6 weeks ago, which made little if any difference in the sound. I asked a mechanic I know (and trust) at the non-dealer where the oil change and tire rotation was done, he said to turn slightly left and right while driving to see if the pitch changes, which may indicate a front bearing problem. There was maybe a slight pitch change in the whine when I did that, if any. He said it might be the start of a bearing problem. I also don't notice any change in the pitch or unusual behavior when making turns.

So is this a tire problem or front/rear bearing issue? I'm going to take it to the mechanic for him to test drive, would I be better served going to a dealer? Given the car mileage, it could very well be a bearing problem, it would certainly be due.

Prius (2004-09) :: Moderate Pitch Whine In Front End Only When Steering Or Turning Right

Have a moderate pitch whine in front end only when steering or turning to right. Gets louder w higher speeds but pitch is about the same. Thought it was a left front wheeling bearing. Also needed new pads and rotor. While doing the job noticed grease all over the lower ball jt. Discovered a tear in the outer axle boot. Net net replaced pads, rotor, axle hub assembly and axle complete. To my chagrin the noise has changed one bit. The noise also doesn't change when I put the car in neutral while traveling downhill. With the hope that I replaced the wrong bearing I have ordered a new one for the right passenger side. When I tried the 6-12 wheel rocking test on the right there did not appear to be any looseness.

Toyota - Prius :: High Pitch Whine Or Hum From Front Right Side Of The Car

I've got a 2006 Prius - bought new in 2006. Yesterday I started to hear a high pitched whine or hum from what sounds like the front right side of the car. I hear it when the car reaches about 48-50 mph and seems to increase as you go faster. Once I let off the accelerator the sound slowly goes away. I know there are a lot of noises from the Prius, but this is one I've not heard before.

Prius (2004-09) :: High Pitch Whine At 50 Mph

I've got a 2006 Prius - yesterday afternoon my wife and I noticed a high pitched whine coming from the front (maybe right hand side) of the car - we don't hear it until we reach about 50mph. It gets louder as we increase speed and then trails off when you step off the accelerator and can't hear it all below 48-45mph.

We bought the car new and are familiar with the various noises the car makes, but this one is new - never heard it before yesterday.

Prius (2004-09) :: High Pitched Whine When Accelerating

My car has 155k miles and I haven't had any previous issues with it. I noticed probably 30k miles ago the beginning of a whine sound when the car accelerates. The noise has been getting louder (it's really not that loud) but I am wondering what this could be. I want to avoid anything happening to the car and want to find out what the problem is so I can fix it.

Prius (2004-09) :: Whine When Stationary And Stop After Few Minutes?

My wife has said that yesterday morning (and also a couple of weeks ago), she started the car and a constant whine came from the engine area. It went a few minutes later while she was driving.

Prius (2004-09) :: 2010 - Whine On Transaxle / Fluid Change

I have a 2010 Prius and need to change the Transaxle fluid. I have the Haynes repair manual, but it only shows the drain and fill plugs for the Gen II. I have found what looks like the drain plugs but am not sure of it. Fill appears to be right next to the CV axle and the drain is straight down from the CV axle. Are these the correct fill and drain plugs?

Also, this transaxle seems to have a whine to it. Whines only at kind of a neutral throttle. Throttle pressure or backing off on the throttle reduces the whine. Is this normal or what?

Prius (2004-09) :: Super Loud Whine From Engine Bay For About 10 Minutes

Yesterday while on an 50 mile I had much more serious whine from the engine bay for about 10 minutes, that I think was from the serpentine belt. I wasn't driving, but my driver (my gf) called and I could certianly hear it on the phone. I could hear it in the cabin, then I could hear it from outside the car. She opened the hood and said it seemed to be coming from the passenger side down by the firewall, engine side. I could hear it while driving and while she was parked and idling.

I'm not familiar with the prius engine bay yet but that area is where the fan belt is i'm guessing if its like my other fwd cars.

It was cold out. She was driving about 55 mph. She had already driven 45 miles when it started. It continued to whine like that while parked and idling, and also while driving. She started and stopped the car and it would start when the car was started. I'm sure she had the heat on the whole time so i can't tell you if it quit when the engine cut out, but i bet it would have.

Then after about 10 minutes it stopped. It started a little bit at start up and then went away. She drove home 50 miles and didn't notice it anymore. I drove it last night in 12 degree city/suburban driving/ highway for 50 miles and never had it come back.

Audi - A4 :: 2011 - Transmission Whine From Front End?

My car has 40,000 miles on it and the warranty ends in the near future. I noticed this winter on some occasions a type of whine (not too loud, but noticeable) from the front of the car. The noise and tone seemed to be proportional to the engine revs. I think I recall the noise stopped when I put the car in neutral while it was still moving. I don't notice it now. I would like to avoid any out-of-warranty fixes if possible. Any thoughts as to the cause?

Touareg :: Loud Whine Developed On Front Drivetrain

All of a sudden after coming back from an Alsp ski trip some sort of loud front drivetrain whine has developed. It's an 05 V8 with 4k miles on it. It's drivetrain because the whine scales with road speed and not engine rpm. It seems to only come from the front too. It starts to get real noticeable around 50mph and increases.

The odd part is I can turn the steering wheel maybe a quarter of a deflection either direction and the sound virtually disappears. I checked out the tires and the tear is good and no usual wear. I am thinking maybe a wheel bearing or a transmission output bearing. I just don't see how anything else could make this whine come out of nowhere so quickly.

Passat (B5) :: Whine When Turning Coming From Just In Front Of Pedals?

new water pump and tensioner pulley, power steering hoses have been tightened yet still making this whine. It did stop for a while after i topped up the p/s reservoir but its fallen below the required amount again and garage has apparently tightened the hoses so shouldn't be leaking.

Don't know if its relevant or not but when i make a left turn and begin to straighten up I hear a clunk sound (sounds like coming from just in front of pedals, not 100%)

Camry 2012+ :: SE - High-pitched Whine From Front Passenger Side Of Car

I'm going to take my 2012 Camry SE in for service sometime in November and experienced a high-pitched whine (very low volume) in the front end of their car. This sound seems to be coming from the front passenger side of the car and has surfaced only within the last month or so, between 70-75 MPH. Above and below that speed range I hear nothing. This car has low mileage; after almost two years, it has only about 12,500 miles on it.

I'm wondering whether it's a trans-axle whine, but it is of such low volume I don't think it would be easy for a tech to diagnose. Also, other than the D1T recall, are there any other TSBs that I should be aware of, and any recent Entune updates that need to be applied? And, whether Toyota has a remedy for D1T yet?

Ford 7.3L Power Stroke (1999-2003) :: Whine Coming From Front Wheel Bearings?

I have some whine coming from my front wheel bearings so I'm going to replace them both. I'm not sure if this had been done on my truck before, but I'm thinking so since I have Moog greaseable ball joints.

Truck has 250k miles on it. I'm going to check the pads, rotors and slide pins. Anything else that might need work? I'm sure the half shaft could use a once over, but I don't keep my hubs locked so they don't turn much in regular driving.

Its a 2011 F-350 6.7 Lariat 4x4 w. 32,000 miles. I also have have a little whine coming from the rear when I take off from a standstill.

Ford - Explorer :: 2004 4X4 - Slight Whine At 55 MPH

I recently had to sell my 1990 Ford Bronco (hence my name) because it failed emissions six times and I gave up. I bought a 2004 Explorer 4X4 with 93K. I am very happy with my new truck. It is very clean and looks like new. I only noticed one thing - a slight whine from the rear end at 55 mph when I am on the gas. It doesn't really sound like a bearing. I read somewhere that Ford put a lighter weight gear oil in the diffs to increase fuel economy, and if you put in a heavier grade then the whine will go away. Is this true? If so, what should I use? The whine is barely noticeable and doesn't bother me, but if it could be eliminated easily by changing the oil I'd do it. I also read that someone did this and a week later the diff blew up. I'd rather have a very slight whine than a diff blowing up! What should I do here?

Ford F-150 (2004-2008) :: FX4 - Hum And Whine At Speed Above 20 Mph Or So

I have a 2004 F-150 FX4 4x4 with 80k with a 9.75 LS, recently I've had the truck start making a humming sound/vibration (similar to the sound/feel you get when crossing onto rumble strips, only not as intense) when at speed anywhere above 20 mph or so, its doing this all of the time. The strange thing about the sound is that is only occurs when I am driving completely straight or to the left, if have the steering wheel just slightly turned to the right of center, the sound and vibration completely goes always until the wheel returns back to center. also I've started to notice that sometimes (not all the time) at lower speeds when let off of the gas and decelerate. I'm getting a very high pitch whine that sounds like a metal-metal sound but only lasts for a few seconds then goes away.

I cant tell where if the sounds are coming from the front or back and i cant decipher which side it is coming from. Also, I don't know if it is related but over the summer, probably june or so, i had to drain the fluid from the rear end and replace and add an extra bottle of friction modifier to get rid of the shuddering problem alot of people with 04's have run into.
