was making the std whirring noises, just jack the car up, and spin each wheel individually, it should make the same noise as your hearing on the road, if not making the noise, check for the wheel that has most play in it, i.e put hands on the wheel at 3oclock and 9 oclock positions and mush with one hand and pull with other, if bearing is gone it will most likely rock back and forth.
