I made a hub puller for that job many years ago. Three straps to three wheel bolts, then bolt a chain to the apex of the straps. Bolt the other end of the chain to the biggest piece of iron you can lift, put a handle on it and swing it like a golf club, straight out from the axle shaft. Stand so the chain comes tight at the bottom of your swing. Never saw one that wouldn't pop off with that kind of treatment.
Use a long chain so the hub doesn't whack you in the legs. Been there, got the scars!
