Placing rear whell bearing
 

REPLACING REAR WHEEL BEARING

At 150xxx miles, lately i've been hearing a waa waa waa noise as I drive. I had this happen b4 on another bonneville a'92 and it was the front. Now it is coming from the driver rearon my '97 . Is it difficult to replace the bearing or should I just get the whole new hub assembly and replace it as a whole. Cost\value would be the deciding factor. :shock:

Click the Techinfo link at the top of the page, and click on Tech Know-How.

I did read that. However i was wanting to know if you could just do the bearing itself or is that a machine pressed part?

The hub comes as an assembly. You can not change out just the bearings, or the sensor. It's an all or nothing thing.

And expensive if done at the stealership ;) I personally have not done one (along with a lot of things on my car), but even though you have ot buy the whole assembly, you are still going to save a boat (pun intended) load of money.

The problem description sounds similar to what I've had on my '92 for a year or so.
On your car, is the wa-wa-wa noise only noticeble at certain speeds, such as from 25-45 mph or so? That's what mine is doing, and it sounds like the noise on my car is coming from the rear driver's side. Please let us know if replacing the hub eliminates the noise.

Does this sound like a loan moan pulsating noise, comming from the rear? Its not a constant noise, just a humming pulsating noise.

The noise was apparent at speeds about 80 KPH, and higher. Seems like this is a normal problem for these cars. I replaced my bearing, and noise was gone. Onto the next noise, and that was last year. You all have NO idea what I went through last year to find multiple noises in the suspension. One wheel had the balljoint (pressed) tie rod, and the wheel bearing, gone at once. Made quite a bit of noise. When all was done, and aligned, new tires, the ride was so much smoother and quieter.

Anyways, sorry about hi-jacking the post. :shock: :)
