2004 Aveo roaring noise from front and rear wheels that increase with vehicle speed. It stops during left hand turns then return when going straight. No change to noise when turning right. I think it may be wheel bearing. How do you replace the bearing?

Hi Chris, I'm glad to help! Vibrating / Roaring sounds can be anything from rear or front diff problems. Drive Line U-Joint problem. Wheel bearing bad. Even transmission problem. You have to pin-point where the vibration is, is it in the front, in the rear, on the right or on the left. Is it in the center of the vehicle and so on. Hope this helps and have an awesome day Chris!

If it isn't the tire and it changes when you turn, I would suspect the wheel bearings.

While driving and with radio off, listen to the noise. Find a road that is clear on which you can drive without any traffic. Drive at a constant speed and make light shifts to the left and right, by doing this, the weight of the vehicle will shift to the apposite side of the steering wheel to which you turn.
When you turn to the left, the weight goes to the right (passenger side) wheel, if the noise stops, you may have a bad wheel bearing.
When you turn to the right, the weight goes to the left (driver side), if the noise stops, you may have a bad wheel bearing.
If the noise does NOT go away, then you may have bad CV's.
Another way to check is by lifting and securing in jack stands. Vehicle in neutral and with your hands, rotate wheel with one hand. Other hand place on suspension component. Spring of strut. If you feel slight vibration, you may have a bad wheel bearing.
With vehicle on jack stands, one hand on top of wheel and other on bottom, try to see if you can move the wheel in and out which may be a had CV.

Quite often it is a bad wheel bearing, a lot of chevy's are notorious for them. A wheel bearing will usually create a growling type noise that is more prominent at around 40-60MPH. If its a wheel bearing you should notice a change in pitch when turning in one direction, for example if you have a bad right side wheel bearing it will be noisy driving straight ahead, then get louder when turning LEFT. If you turn right the noise softens. The weight distribution of the front end will be greater on the right side when turning left. Of course the works in the opposite direction. If the noise remains constant going straight and turning it could be a bad tire. Visually check the tire for pressure and bulges in the side wall. You didn't mention what type or model vehicle you have, because in some cases the rear wheel bearing could be causing the noise.

THIS NOISE IS CAUSED BY A POSSIBLE WHEEL BEARING
WHEN YOU DRIVE THE VEHICLE YOU SHOULD HEAR A ROARING NOISE AND AS YOU GO FASTER THE NOISE WILL GET LOUDER AND WHEN YOU TURN THE WHEEL FROM SIDE TO SIDE THE NOISE WILL FADE IN AND OUT. THIS IS AN INDICATION THAT THE WHEEL BEARING IS BAD.
ALSO ANOTHER WAY WOULD BE TO JACK UP THE FRONT OF THE VEHICLE, BLOCK OFF THE REAR WHEELS SO THE CAR DOES NOT ROLL BACK ON YOU, THEN PUT THE CAR IN NEUTRAL AND GO TO THE WHEEL PUT YOUR HAND ON THE STRUT BASE AND SPIN THE TIRE WITH YOUR OTHER HAND YOU SHOULD FEEL A GRINDING NOISE. IF SO THE WHEEL BEARING ON THAT PARTICULAR SIDE IS BAD AND IT NEEDS TO BE CHANGED

are your front right brake pads worn more than your front left? if so probable cause is the rotor. if not, most likely wheel bearing

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.

That's a hub bearing. Replace the one that's doing it. I'm assuming this 'roar' is coming from the front, NOT the rear.

Sounds like your wheel bearing is going if no other noises present when braking

first i would check the tires , are they cupped or chopped on the tread? run your hand over the tread and see if it feels rough and uneven. take the truck to a auto repair shop and have them jack both front and rear axles off the ground, put the truck in 2 wheel drive and run the speedometer to the speed you usually hear the roaring noise, if you don't hear the noise , put the truck in 4 wheel drive, turn off the traction assist if it has one and run it to the speed you would hear the noise. if you hear the roaring noise with tires off the ground, the problem is in the drivetrain, (engine, transmission, transfer case, u-joints, differentials or the front left or right cv halfshafts or u-joints). the older models (97 98) had the front two driveshafts from the differential turning all the time, they engaged in 4 wheel drive from the transfer case and a solenoid on the front differential. depending on the miles you have on this truck, the most likely areas i would look at would be the tires, u-joints/cv joints, and front and rear wheel bearings. thanks and good luck.
