Ok, you are only at the beginning of getting the rotor off. You have to pull the snap ring that's on the end of the axle stub off and the snap ring on the inside of the hub that holds the aluminum locking hub piece in place. Once you have the locking hub guts out, then you have to remove the two nuts that hold the wheel bearings in place. This takes one of two styles of socket, hopefully you have the easier to find of the two which is a big socket with four tabs. If you have the other, you might have to resort to the hammer and chisel method of getting it off using the chisel to spin the nut off.
You can get the later style of four slot nut from NAPA which will make getting the bearings preloaded much easier.
Once you have the hub/rotor assembly off, you need to remove the inner and outer wheel bearings and separate the rotor from the hub. My preferred method is to use a 5 lb hammer and pound the studs out. You did buy new studs right? If not, get them.
Once the studs are out, the hub and rotor should separate with relative ease. The approved method of reassembly is to press the new studs into the hub with a press. In a pinch I have used the big hammer and a drift to put them back in, but you run the risk of damaging the lip of the hub doing this. I have also used a wheel and the lug nuts with an impact gun to pull the stud in, then seat it with the hammer and drift if it won't seat with the gun.
From your last pic, I can't tell if you removed the snap ring on the stub (in the center) or the outer hub. Both have to be removed in order to pull the rest of the locking hub guts out. I thread one of the screws back into it in order to have something to grip while I'm pulling it out.
Later,
Joe
