Excuse the improper names, but it is a little late to go searching for my manual.

First you need to remove either your auto or manual hubs, or in the case of the genII your hub slugs. You need to pop the outer caps off on the genII first so you can take the circlip off the cv axle. Be careful as sometimes you have shims behind the clip and you don't want to loose them. Once the clip is off you can remove the bolts holding on the hub slug and pull it off the cv and the hub body.

If you dig through the grease you will find two screws. These screws go through holes in the lockplate, and lock the adjuster (tensioner what ever) and keep it from moving. They are philips heads, I like to use a impact screwdriver to remove them as they are sometimes hard to get out with a regular philips head without stripping them.

With the two screws out jimmy the lock plate out of the body of the hub. Behind it is the tensioner that holds the hub together and keeps the proper load on your wheel bearings.

If you have your special tool here is your time to use it. Otherwise take a punch or a philips head, and use a hammer to loosen the plate counter clockwise. DO NOT, I REPEAT DO NOT USE THE TWO THREADED HOLES TO LOOSEN IT. If you do your going to curse yourself when your try and put it all back together.

Once that is off the hub/rotor will pull off the spindle. Be careful the wheel bearings can fall of.

Repack them and clean the whole assembly before putting it back together.

Also, do a search on wheel bearings, there are several good threads about reinstalling them, seating them, preload, all that good stuff.
