Re: first problem
This is the specs from the manual for the bearing.
Adjust the wheel bearing end play by turning the hub nut (4) in stages while pushing and pulling the rotor firmly
back and forth. Adjust end play to 0.01–0.02mm.
8. Tighten the hub nut bolt to 11 N·m (8 ft. lbs.) and recheck the wheel bearing end play.
