Ok, so if I understand correctly, the dial comes off the hub, the 54mm nut comes off, then the hub/rotor assembly comes off, then separate the hub from the rotor, and assembly is the reverse? that sound right?

Also, what kind if grease should I use in the bearing areas?
When is gets super cold around here (around 10-15 degrees) the bearings will howl for a minute when first driving.
