how do you know when your wheel bearings are out?

Mine started humming, the faster I drove, the higher the pitch of the humming noise. Since it was a rear bearing, we put car on rack, put it in gear and spun the wheels about 35-40 mph. It because real obvious which one was making the noise.

on mine sometimes I hear some noise inside the car but that can just be road noise due to me running 35 series tires in the front

my car starts to shake a little at 70 mph a little and I have already had my tires balanced and car aligned even though he couldn't adjust my camber cause i don't have my camber kit yet.

im glad i found this post im confused. i dont know if im having wheel bearing issues or cv joint boot band issue... this is my first time experiencing this. i am feeling and hearing a slight knocking as the wheel spins on the front right side when im not accelerating and when i hit about 80mph it vibrates only from the front right side.
