I believe you have to change the bearing retainer, bearing and seal all at the same time. That requires a press to install the bearing retainer. Looks like my RJ60 rear has developed a slight seal leak and will require the same work to fix (I still need to remove the wheel & rotor to verify before ordering parts).
