Question about Cars & Trucks

1 Answer

I have a 1999 buick century custom. My proble is that i am hearing a humming sound comming from the front of my car. I believe i have a bad wheel bearing from what i have been reading on here from other buick owners. I have just had my brakes done so that is not this issue, when i am driving straight i can hear a 'humming' sound. When i turn slighty to the left the sound goes away, a slight turn to the right and it gets louder, can anyone tell me which bearing needs replacing/should i just do both sides? Can i change just the bearings by themselves or do i need to replace the whole hub assembly?

It sounds to me like it is your left front wheel bearing. the best way to check this is to raise both wheels and spin them by hand there will be some noise from the pads rubbing the discs but the side with the bearing gone will be noisiest.you can replace just the bearing.I hope you find this helpful

    while this is test is accurate for a wheel bearing that is loose or worn severly it will yeild little result from a bearing that is still functional sound an alternate test method is to sway the vehicle from side to side at slow speeds when the bad bearing is unloaded the noise will stop temporary usually the opposite the side (if you turn left and the noise decreases its the right side and vice versa)

You must replace wheel bearings in pairs to avoid loading the old bearing and, in time ruining your new bearing hub it is possible that you have already damaged the new hub

SOURCE: One side front wheel bearings need changed How do I know which?

It may be your alignment but if it is wheel bearings jack up the front of the vehicle and try to rock or shake the wheels by hand if there is play or it does move it is your wheel bearings

SOURCE: 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.

SOURCE: noise in front end, sounds

You say the rear wheel axles and bearings have been replaced, you mention nothing of the front wheels, you have the symptoms of a front wheel bearing being worn out, remove them and check for pitting in the bearing rollers or the bearing races, I am sure you will find a problem. Hope this helps solve your issue with the bearing noise.

I have a 2000 Buick Century limited. While driving or turning either direction I can hear grinding. When making slow sharp turns either way can feel a thumping. What would it be?


Wheel bearing would be my guess , without hearing the noise ! CV joints make a clicking sound when turning , when bad ! Have it checked by a qualified repair shop before your wheel falls off .

Where is the water pump in a 1999 buick century


The water pump is on the top. While facing the engine (front-wheel drive), it is the closest part to you that is on the belt. It is in front of the power-steering pump (slightly lower).
