I would have this checked out ASAP. Could be a loose wheel, bearings, brakes, and/or suspension parts.

Check for a failed wheel bearing, jack that wheel up and rock back and fro, there should be no movement, spin and ther should be no nasty noises, repair any faults here and get the tyres checked for condition and if ok, get a balance done.

This could also be your brake rotors. If one is too far damaged, it can cause the wheel to make a noise (even when the brake is not engaged)Having one rotor more deteriorated than the other can cause the steering wheel to pull to one side as well.
