heres a step-by-step. Start off my removing the allen screws that hold the cap of the locking hub on. next, romove the cap and remove the snap ring on the end of the exle shaft. Next remove the large snap ring that is set into the snout on the rotor assembly it helps to press in on the hub because there is a large sping behind it putting pressure on the snap ring and then remove the locking hub. after you get the hub off, you will need a spindle nut socket. Its a large socket with four prongs on it. Use it to remove the spindle nut and then pry off the lock ring and remove the second spindle nut.
Now you should be able to remove the rotor assembly. The outer bearing assembly should come out with no trouble, the inner bearing you can pry past the seal, ruining the seal. But thats ok, you should replace that anyhow. Next you have to drive out the bearing races by using a long piece of metal, preferably something soft like brass but I just used a long bolt I had handy. Just tap the race on opposite sides and make sure it comes out evenly. To put new races in just use your old ones as the installer and pound on those. the inner one can go on pretty easy because there isnt very far to drive it, just make sure you keep is straight. they outer race takes a bit longer but just take your time and make sure you keep it straight.
Sorry this was so long, I just went through this a few weeks ago and wanted to share my experience.
