Hi folks, I have a noise in the front of my truck. It sounds like a out of round tire kinda like a flat spot or something clolose to that. I had the tires checked and rotated but the noise persists. Could this be a bad hub bearing???. Just what kind of sound does a bad hub bearing make?? if any and how can i check it. Thanks..... Truck is a 97 F-150 4x4
