Wheel bearing on rotors?
Best thing to do is down load the factory service manual.
Do a search on here to find it.
The rubber thing is just a seal, remove the seal and the bearing will fall right out.
The bearing rides on a race, if you replace the bearing, you have to replace the race.
The race is seated in pretty tight so you need to remove it with a soft brass or aluminum punch so you dont scratch or gouge the rotor hub.
