I think the bearing is bad because I can hear a wah wah wah sound coming from the side of the rear end. Speed changes the frequency of the sound. Higher speeds (over 60) can be felt as shaking develops throughout the entire car, almost like out of balance tires. It does it whether or not I'm in gear, with or without the engine on. When the rear of the car is jacked up, the passenger side wheel spins by hand easily, where the driver's side has a noticable resistance throughout about 2/3 of its motion range. The resistance is there even when the drum is pulled off, so I know its not a rubbing brake problem. Do you think I'm diagnosing this correctly? An axle upgrade is not in order - I appreciate the heads up.
