close, but easier way. jack up, remove wheel. remove brake system. with flat head work around the dust cap and hammer it off slowly. you never should need a new one. remove cotter pin, nut, washer and then the first bearing you see. put nut back on a few turns, pull rotor towards you. this removes the rear bearing and seal at once.
clean and repack bearings with grease (i use Moly) and put large baring in the back of new rotor. tap in seal working around it. place on rotor, place in small bearing. place washer on, then nut. snug firmly while spinning the rotor, then back off half a turn and torque to 18-23 inch lbs. install cotter pin, dust cap and put breaks back together.
be sure to clean off any old grease before putting it all back together. brake cleaner works great.
