Stupid Brake Question

[detroit72k5]

I've replaced the pads and rotors on my other cars in the past, but for some reason I'm having a rough time with the front rotors/hubs on my 4wd blazer. The calipers came off fine and I took off the hub cover, but I'm not sure if the rotor and grease/dust cover are just supposed to hammer off or if I have to take out some inner components of the locking hub to remove them? I stared at it and thought I could figure it out, but figured I'd save myself some time and just ask the experts.
Thanks!
