Alright guys so i have been experiencing humming sound from the back , the faster i go the louder it gets, so i figured forsure wheel bearing, so i bought 2 bearings and had both rears replaced, went to drive the car and noise is still there hasnt improved, any idea on what else it can be? brakes? rotors?

 

Brake may be rubbing the rotors. May be a bad tire. Any unusual wear on that tire?
