Lately, I have been getting a low speed "rubbing" type feeling in the steering wheel. I noticed the RF wheel rotor rubs a little more when I spin the wheel after driving. I removed the caliper so I could spin the rotor freely. There is a slight rubbing type sound coming from the center hub. Is it normal to have some noise from the bearing or is it gone bad. I haven't check the other side yet to compare the noise level. I also suspect maybe its going bad because I have had a lot of tire defect messages. Any thoughts
