Noise from front drivers tire

I am getting a whirring noise from my front drivers side wheel. I replaced the Bearings and it still made the same noise. (to be fair it sounded like bad bearings) I replaced the Calipers and brake pads and the noise is still there.(Good Year said the caliper was pushing the brake all the time and that it had melted and cracked the brake pad) Both times a different mechanic made the diagnosis. What could it be if not these two things? Oldsmobile Alero 6 Cylinder.
