You have to remove the hub lock-bolt/nut on the end of the spindle under the grease cap, then disassemble the entire hub/bearings/seals, separate the two pieces (rotor from hub), put back together with new rotor, re-pack bearings with new grease, install new seals, and re-install the unit on the spindle, then tighten the locknut back to exactly where it was before, and tighten its little allen bolt to lock it in place. Then put some extra grease around it/in the cap, re-install grease cap, re-install brake caliper with new pads, and then re-mount wheel.
Nice and easy! Only takes hours!
