They have a couple of different adapters for slider hammers to remove the axle from the transmission a U clamp type that fits around the axle end. Also one that goes between the axle and transmission.

Or you could try gently prying the axle out of the transmission with a pry bar. The best way would be to use the slide hammer adapters that way you don't have to worry about cracking the transmission case.
