First you will need a pair of needle nose pliars. Remove this locking ring circled in red.
Then you can remove the hub assembly.Next you will need a pair of snap ring pliars to remove the snap ring that's holding the stub axle in place. After that you will need the hub socket that has 4 prongs. Remove the outter nut to access the flat 4 pronged hub activation washer. After that you have 1 more hub nut that takes the 4pronged hub socket. Once all that comes out and you have reomved the brake caliper the hub and rotor assembly will pull off. To seperate the hub from the rotor you have to tap out the wheel studs...
