Ok, here is a cut and paste of what I was after...
Now place the nut on the spindle and tighten it by hand until it won't go anymore. Spin the rotor or drum a few times back and forth and then tighten the nut come more by hand. This insures that the bearings are seated in their races. Do it a couple of times until you can't get it any tighter by hand.
Now tighten the nut ¼ turn, no more than 16 foot-pounds. If you have a castellated nut, line it up with the hole going through the spindle. Install a NEW cotter pin and fold it over. If you have a retaining ring, place it on the nut and install the cotter pin. Never reuse the old cotter pin and make sure you do install it. Basically this is the only thing holding the front wheel on.
