I want to re-itterate. Don't knick the inner axle oil seal. Take it nice and easy when you slide it back together.
I don't know how the others do it, but I pull mine by undoing the brake caliper and then the four bolts that retain the hub to the knuckle. Once the whole assembly is out I work on swapping the axle, hub, and rotor. (As Needed) You might consider replacing your lug studs while you're there.
I pulled mine apart to put on new rotors, and reassembled it with no trouble out of the axle seal. I pulled it all again to put in new hubs and the factory axle oil seal went out. I've tried installing new ones but i think i'm going to have to get DC to do it.
Good luck with yours.
On the puller, If you can't find a puller like he posted, Napa has one that is just two arms with hooks that can press out the axle from the hub.
