I hear what sounds like a humming noise

One of the pulleys on the motor is probably wearing out , ie. alternator , power steering, if you can't tell by ear take the tension off the belt and see what one has any play in it ,

Is it coming from one side more than the other? Maybe a wheel bearing going bad

I will check play in pulley. hopefully is Not Bearing....although I think perhaps the bearing is problem, will take in Monday
