I would also take a look at the tires for signs of wear and possible a stone or some other object that is stuck in the tread. A stone that is at the level of the tread will make a humming noise as it makes contact with the pavement. Aso, wiggle the tires side to side while you have it up; they should be solid. If there is any play it could be sign of a bad wheel bearing.
