Remove the lower ball joint/control arm nut from the spindle. Use a pry bar to get the lower control arm separated from the strut.
Use an impact wrench/gun to remove the spindle nut, (nut holding axle in the center of the hub). You can do this by hand, but it is pretty tuff. There is sometimes some sort of cotter key or spring lock that is suppose to hold the nut in place from backing out, if you have one, remove it. 50/50 chance on if it is there or not.
Them pull out on the strut some, as in AWAY from the transmission. Using a heavy hammer tap the axle shaft in the direction of the tranny. It will normally break free and move pretty easy. Keep tapping until it slips easily out of the hub. Move the spindle one way or another to get it out of the way. Then using the pry bar, pry the inner part of the axle next to the tranny away from the tranny...
Install is in the reverse..
