the races should be replaced when replacing bearings, on principle.


the bearings do not need to be touched at all to replace the rotors, but one may as well repack them and replace the seal, as it will be damaged on removal.

the tools needed are -

17mm lugwrench to remove tire
prybar fro bearing cap
5mm allen for locknut
channel lock pliers for locknut
19mm for calipers + 12" wire to hang caliper from sway bar
10mm allen socket + 6" extension + 18"or longer breaker bar or impact wrench for rotor to hub bolts. upon removal of hub, attach it to the wheel w/ 2-3 lug bolts so you have leverage. reinstall w/ locktite blue.
bearing grease
dial caliper and stand to set bearings.
