slogoer,
It's alright to apply some heat to the axle 'eye'...it's a forging and was born of heat!
Doing this job while the axle is on the truck, and swinging room is at a premium is twice as tough.
Heating the eye, spraying with WD-40 or the equivalent and beating with a very large hammer and piece of bar stock is about it.
The king pins are supposed to be tight in the axle eye..if yours are, count your blessings.
Taking the axle off for serious beating, or a trip to the machine shop isn't that difficult, and can save knuckles and fingers.
The hubs and backing plates will be pulled anyway when you clean and re-bush the spindles and it gives you a chance to inspect other components.
The key on this project is to out think the king pins. If they detect a weak spirit, they will not move. Good luck.
