Hub bearings shot I took my GXP in to get an alingnment & I was told that my hub bearings were shot, I'll be at the dealership tomorrow. My hub bearings on my 98 didn't go until after 100k.Up until now I've had 0 problems,I just had my 35k mile service done about a month ago & they found 0 problems. I'm thinknig of trading her in on a Trailblazer SS,wich was my #1 choice to begin with. Next time I'm going to follow my first mind. Should I be as mad as I am?
My first choice was a TBSS also. But the dealer that had one I wanted lost my business. I wish I could have gotten into the TBSS, but I'm content with my Impala.
ps. I'm at 28k and my PS front wheel bearing groans.

It's just not because the bearings went bad. I'm the type of guy that keeps a car for a while so with all of the problems I'm hearing & suspecting I'm going to encounter I'm just debating if it's wise to either trade it in on something now while my debt to profit ratio on it is low(I only owe about 6k on it) or just keep extending the warranty.BTW Does anyone know if you can extend an already extended factory warranty.When I bought my GXP I had the 36k/3yr factory warranty exended to 75k/5yrs.

Here's a question. I run my 20's in the summer &switch to the factories in the winter. Would mounting 20" wheels cause the bearings to prematurely wear? If so looks like if decide to keep her I've got a set of 20's for sale.

A low noise at first, can become loud. Kind of like pulses from center dash back to seats. If it is felt closer to the drivers seat it is the passenger side and if it felt closer to passenger seat it`s the drivers side.
To TEST your front wheel bearings, lift the front of car so the tires are off the ground. Get a 4x4x1' or like peice of wood lower the car enough to load one tire on it leaving the other free. Carefully get in and start your car, turn off the traction control and stability control. Now carfully put it in gear (D) and let the free wheel rotate on it`s own. Go to the free spinning wheel and reach in and lay you hand on the coil spring. IT SHOULD BE VERY SMOOTH, no vibration at all. If there is a vibration you can usually tell how many rollers are damaged by the pulse just count them not that it matters, because the bearing is still in trouble if you only count one.
Now apply the brake and park then repeat everything for the opposite side.
I do this everytime I get an oil change. The guys are pretty good and it does not take any time at all when it is on the hoist. I explained it to them and they are good with it and the 10 bucks I hand him when done.
You can also tell while driving, turn everything off and going straight and smooth , listen closely. then with a very little effort on the wheel first left , just a little and gentle the noise will go quiet and the same when done to the right. This is not as accurate but does tell you if you should be checking more closely.

I went to the dealership today to get my hub bearings repaired & it turns out both sides were bad.Yes the hub bearings are covered under the 5yr/100k powertrain warranty for all of you who were unsure.Those idiots at the dealership known as service writers tried to tell me that my 5yr/75k extended bumper to bumper warranty I bought at the time of purchase was in fact a USW aftermarket warranty that requires a $100 deductible. I spent all of an hour argueing with them, until I finally had to have my wife bring my purchase contract to the dealership,which by the way was 30 miles away.Yes,I had a good day.

I had to replace one of mine but it was for an electrical fault. The wires for the speed sensor were chafed and would short out causing "Service ABS / Service Traction / Service Stability" errors.
Popping that damn axle out of the hub was a real PITA! In fact, I decided to just replace the bad one even though I had purchased two as I planned to replace them both. Now that I don't have the car anymore, I have a brand new hub bearing sitting in a box in my garage if anyone is interested in saving a little dough.

I have this noise in the rear drivers side, like metal grinding when I'm driving. It's a constant noise that gets louder at the same point during every rotation. I thought it was my worn brakes but it might be the wheel bearing.
how would you test the rears?
