On my 93,I am getting a noise coming from the right front wheel.I dont really know how to describe it, kinda like a dull humming sound.The sound speeds up and gets louder as the car speeds up,and the opposite when the car slows down.It does it when I am going straight and when I am turning left,but stops doing it and is silent when turning right.I checked for tire rub but cant find anything,and there is no gouging on the inner tire so it doesnt appear its rubbing anything.And the wheel itself seems to be secure and doesnt smoke or smell like anything is burning---so??? any help would be appreciated
