Do NOT use a lug nut type puller. Good way to ruin a hub.
Do NOT use a hammer of any size. Good way to have to
re-machine the threads and end of an axle.

Take the axle nut off and replace it with a HARD HIGH NUT run down within 3 or 4 threads of the axle.
Use a HIGH QUALITY clamshell type puller.
Pull it up as tight as you can.
PUT ON EAR PROTECTION, this is going to be loud when it comes loose.
Now, use a rosebud or very large tip acetylene torch and heat the exposed part of the hub behind the puller.
Re-tighten the puller as you go. No need to get even dull red.
BANG!
This is about the only way you can get them loose if they have been lapped on as in race cars in the old days.
No buggered threads or bent axle ends either.
DO NOT TOUCH ANYTHING TILL ALL COOLS!

And now a word from the soap box.
All early Ford type rear ends should, if used on the street have either bolt on drum clips or weld on safety hubs.
The people you could run into head on in case of an axle failure will thank you and it may even save you having a bashed up fender like if a wheel came off and rolled down the street.
