You just have to remove the knuckles. You can leave the housing in place. You'll have to remove the wheel/tire, caliper, big nut (1 11/16 socket?) on the end of the shaft, the 4 bolts (14/15 mm socket?) that hold the rotor/hub/bearing on (from the back side), the inner/outer shaft assy, the ball joint nuts, then the knuckles should come off with a little persuation with the BFH. Prolly a few more things need to be removed, but you get the idea.
