THIS NOISE IS USUALLY THE HUB. HAVE SOMEONE GO WITH YOU ON A TEST DRIVE. GET THE ROARING TO HAPPEN AT ITS LOUDEST AND GENTLY SWERVE THE CAR LEFT AND RIGHT. DON'T BE SURPRISED IF YOU THINK BOTH HUBS ARE BAD. LIFT THE FRONT OF THE CAR AND PUT IT ON JACK STANDS. PULL OUTWARD ON THE BOTTOM OF THE TIRE WHILE PUSHING INWARD ON THE TOP OF THE WHEEL. IF THE WHEEL MOVES EXCESSIVELY YOU FOUND THE HUB THAT IS NOISY. USING A MECHANICS STETHOSCOPE YOU CAN SOMETIMES HEAR A ROARING TYPE NOISE ON THE BACKING PLATE SIDE OF THE HUB WITH THE ENGINE RUNNING AND THE TRANS IN GEAR. TRY NOT TO GET THE SPEED UP TOO FAR ESPECIALLY IF YOU CAN HEAR THE NOISE AT LOW SPEED, YOU DON'T WANT TO VIBRATE OFF THE STANDS.

Wheel bearing? If you turn left and it gets louder. It is the right wheel bearing. And vice versa.

My 2000 Buick LeSabre makes a high pitched noise when accelerating that gets louder as speed increases, until it sounds like a Go-Kart. When I turn the wheel to the left during a curve, the sound goes...


Sounds like you need a wheel hub. Jack the car up then safely pull the tire with your hand on the top and bottom of it. If it moves at all you need a wheel hub, some will barely move at all.

What kind of noise will you hear with bad right wheel bearing? It sounds like a whirl behind radio and gets louder with increased speed over 35mph.


the noise should change or go away when you turn the wheel to the right or left. if it does it sounds like you have a bad wheel bearing. Typically if you turn to the left and it gets louder its the right side if you turn to the right and it gets louder its the left side. Or if you turn to the right and it goes away its the right side and if it goes away when turning to the left it is the left side.

Another thing you can do is safely jack up the front of the vehicle. With the transmission in neutral rotate each wheel by hand while holding onto the strut spring with your other hand. You should be able to feel the noise you hear in the strut spring if it is the bearing.

Bearings or cv joint?


Wheel bearings.
For quickly ruling out the CV Joint, in a parking lot, turn one way in a sharp circle, then the other way circle sharply. A clicking sound is indicative of a bad c/v joint or 1/2 shaft.
Humming while in motion (most of times it will only occur during a specific speed range - over a certain speed goes away) says a wheel bearing is shot.
Normally you should replace both at the same time... however you can check with a laser temp gauge each front hub after driving. The hotter one is bad - or a less scientific approach is to swerve going down the road. and listen for an decrease in noise going in one diretcion over the other.
If you are turning the steering wheel right, and the noise goes away, the right bearing is bad and vice versa.
