sounds like you have a wheel bearing that's bad, some vehicles have the wheel sensor mounted right to the wheel bearing. best way to check is drive down a straight road at a steady speed, then turn the wheel left, like your going to change lanes, then do the same but this time turn the wheel to the right. Now if the noise is louder when you turn left, then that tells you the right wheel bearing is bad, if you turn right and the noise is greater, then your left wheel bearing is bad. the reason for this, is when you shift the vehicle left or right, the weight of the body shifts the opposite way that you are turning, thus putting more weight on the bearing, causing it to get louder. Hope this helps.
