The biggest thing of importance is when you install the new races in the rotors. You have to make sure they are FULLY SEATED where they need to be, or else when you get the car back together and drive it, the force of driving will seat them, and you'll have a set of loose bearings, and a possibly dangerous situation on your hands.
When I was a younger guy, thinking I knew everything, I did this once. Drove the car, and couldn't figure out why I had a popping noise as I was driving it down the road, then wondered why the steering got extremely loose. We pulled off the highway, and I had my buddy walk beside the car to see if he could figure out where the hell the noise was coming from, and he stated, "Hell, your wheel's about to fall off!" WHAT???? The inner portion of the bearings had seized to the spindle, the cages of the bearing rollers were both broke, and the bearings themselves weren't even rolling on the races anymore. All because I didn't make certain the races were seated into the rotors properly. So word to the wise, either have them pressed into place, or use the "hillbilly method" and drive them in with a brass punch. Brass won't screw up the race surface if you happen to slip.
