Question about Cars & Trucks

1 Answer

My car is making a noise, almost like an airplane taking off, whizzing kind of noise, only in between like 10-20mph. At 20 it just goes away. Same for deceleration. Get down to 20 noise starts and noise stood when I stop. Turns make no difference on the sound.

Kinda sounds like a bad wheel bearing, but can't really give you a good answer without more info, type of vehicle, year, well maintained? stuff like that and maybe an aproximation of where the sound is coming from. also if your car has some damage from an accident or something, it could just be that sweet spot in the speed where it makes noise. Good luck and dont be afraid to ask for more help.

SOURCE: 2001 Cadillac Deville; noise after the engine starts

The whine sounds like the power steering or the alternator, as far as the idle issue goes try this clean the intake throttle body and idle speed control valve with carb spray, disconnect battery for 5 min. then reconnect and drive a few miles to reset idle strategy. The car will try to die when you spray the intake, hold the idle up to prevent that, use at least 1/2 the can of carb spray.

Bad bearings could indeed make the noise you are hearing. Are you hearing it only at certain speeds or all the time no matter how fast? CV joints won't make that noise, they will click when you turn your wheels if they are bad. How long have you been driving your car with this noise...if it was just recent then I doubt the transmission could be it.

The best way to check the bearings is to jack up the front end of the car and put it on stands (put jackstands under the car and then lower it with the jack until it rests on the stand fully...NEVER EVER get under a car with it supported only by the jack!), then try to wiggle each front wheel by grasping the bottom and the top of the tire and then pushing and pulling (left hand at 12 o'clock, right hand at 6 o'clock then push with left hand and pull with right hand and vice versa), if the wheel moves at all, you have bad bearings.

CV joints can be easily inspected as well, while the car is up, take a look at the CV boots, these are protective covers that keep dirt out of your joints, they are rubber and are flexible. If you see any type of cracks or breaks in the boots, remove them and inspect the joints for wear; if the grease looks clean (no dirt at all in the grease) you can probably get away with just replacing the boots, but remember to re-grease the joints!

Check your transmission fluid for color and clarity; under the hood you should find two dipsticks; one os for oil and the other is for the transmission. The oil dipstick sits on the side of the engine and goes into the oil pan; the transmission dipstick will come up and out of the transmission; check the level and clarity by pulling the stick and looking at the fluid on the stick. If the level is in the normal range and the fluid looks red and clear, the transmission is fine.

Now, if you prove the bearings are bad, you could do them yourself but I recommend not to try it unless you have years of experience working on cars...I'm not trying to say you can't do it yourself but I am saying you should let a professional do this repair; those bearings take a lot of abuse and should be replaced by an experienced professional.

If you insist on doing this yourself, let me know here and I will walk you through the procedure.

SOURCE: 2006 Dodge Gr. Caravan. Loud humming noise upon

Misalignment of the belt, incorrect belt, worn or loose tensioner, Too tight of an adjustment (many service centers do this on purpose so when the belt breaks in it becomes properly adjusted, I do not believe in this philosophy), The belt is actually one long belt called a serpentine belt.....

Roaring engine noise in cab when idling. Idles at 500-950 rpm..When raising rpm in idle noise goes away.2002 GMC Envoy 6 cly.

Should idle between 500-600. Clean your throttle body with the battery disconnected to help with the fluctuation. The roaring very well could be your fan clutch. Fan clutches are a known problem with our platform. If engaged, will sound like an airplane.

Firstly check if you have gearbox oil in it seldomly so happens that a gearbox makes a noise but when it does make a kind of winding noise the gear inside the box has gotten damaged. Sometimes when lucky if you add gearbox oil the noise goes away.

I have a 2003 Impala that makes a noise as the car/engine goes faster, the sound is like a model airplane engine noise, I replaced front brake pads and checked rotors, Other than this noise the car runs...

Is it a driving noise or a noise only when the motor is running with the car stationary??If its a driving noise then it could be a wheel bearing otherwise its an auxillary drive Ie alternator or pas pump etc

In 2 wheel drive there is a whirring sound from the front end followed by a loud clunk where it feels as though you have run over a large rock or chunk of ice. Does not seem to occur in 4wd

if the whirring you describe sounds like an airplane and increases with speed that would be a wheelbearing and it may be loose to cause the clunk noise. when it is put in 4 wheel drive that can load the bearing up and noise goes away.
