If you are replacing the rotor then you need to do this to separate the hub
from the rotor.
Pry out the inner bearing seal
Pull out the inner bearing
Carefully drive out races
Note:
Be careful not the gall the hub when
driving out the old races. That can make getting the new ones in a real pain.
If the hubs are already galled, a small sanding drum on a rotary tool can be
used to smooth the surface. (HizAndHerz)
I like to throw the races in the freezer a couple of hours beforehand and warm
up the hub a little bit to make the races go in easier. (HizAndHerz)
Here is the old race. It is easy to see the wear

Install nut lock
If the nut lock's V slots do not line up with cotter
pin hole, simply pull nut lock off the nut, rotate the nut lock then reinstall.
The V's are offset so
that they will line up
Install NEW cotter pin
Installed
Bend cotter pin
Note:
Cotter pin not installed correctly. The
pin goes with the round bulge facing out. Before using a new pin, hold one end
in a vise and twist it's other end 90 degr. Now you have the famous Rolls Royce
twist that allows a correct install. so that the two legs of the pin can be
folded back against the outside of the retainer back to front w/o hitting the
grease cap or having to cut off one leg of the pin.
