It sounds like you have a bad wheel bearing. If it stops when you turn right, chances are it is the right front because in a turn, the vehicle's weight is transfered to the opposite side of the car. Thus, a right turn would add weight to the left and remove it from the right and the noise would lessen.
Let me know if you have other questions.
