I wouldn't doubt it being the wheel bearing. That is probably the worse part they put on our cars, in close contentions with the LIMG. When you turn the wheel to the left or right does the noise get any louder when driving?
It won't make any noise when you are stopped, but it will when you start going? Reason I ask those two questions is that if you answer yes to both of those, then it has to be the wheel bearings. I just replaced mine because of similar circumstances, and it was my passenger side wheel bearing. When I turned to the right, the noise would get louder, noticably.
