Jacking the car up a doing a "Wiggle"test will not pin it down.A visual is needed.Remove wheel and rotor,the bearing is pressed in to spindle assy. and about 6" in diameter.These are not serviceable(packing with grease)You have an 06' The likely hood of a bearing failure on a 3 yr old car is not likely.Tire noise is the more likely culprit.Check tires for wear and alignment.One degree of misalignment is like dragging your tire sideways 100 feet for every mile and will change the face angle of the tire to the road contributing to noise/wear.
