Wheel Bearing

Lately I have been getting a loud humming from my rear right side. I have had older cars with wheel bearings gone and they sounded the same. I have also replaced wheel bearing on other models easily. I took the wheel/hub off today and instead of a cotter pin removal and popping out the bearing it looked much different, and had a white plastic washer on it that made it look as though it was not to come out. Has anyone replaced one on a 97 Breeze before. Is there much trouble or something I should know? Also I have notice and rubber type of burning smell form the same wheel after driving. Could it be a brake problem and not a bearing? Any help appreciated.

I replaced both front hubs(weelbearings on my wifes 96 breeeze, its really not bad at all. i am a mechanic but i know anyone with any ability could do it, just go slow.

are these pressed in? quick run down on how to do. thanx

The wheel bearing is part of the hub assembly wich is bolt on. I have the same problem with my 98 breeze. I was wondering if anyone knew the axle nut torque specs?
