Is there play in the wheel bearings or more likely is anything contacting the brake disc as you turn the wheel, perhaps the brake disc water/dirt shield got accidentally bent and is contacting the the brake rotor.

ROUND 2...the shield is not toching .when its on the rack and theres no wieght on the wheel there is no noise(it was in 4 wheel drive ).so I guess its the hub/bearings?I also notice 3 large wheel wieghts on that rim.could a bent rim cause this noise,i am getting price quotes and it seems to run around 600.oo bucks up here in seattle.is that a fair price for part and labor..thank you,chris
