Iv'e never been lucky enough for it to slide right out !!!!!!!!!!
Try this, put the brake drum on the lugs reversed (backwards), put the lug nuts on reversed(backwards) and only screw em on 3 or 4 turns, now push the drum all the way to the axle flange and sharply yank it back against the lug nuts, If this won't pop the axles out you might as well go buy or rent a slide hammer.....
