Have you removed the outer slotted flat washer and outer cone bearing? Pry them out and maybe use a length of 2" x 4" on a floorjack to put upward pressure against the outer end of the hub's snout. If the jack lifts the front end off the jackstands, stop. Release the tension and repeat this procedure a couple times.
If you haven't removed the outer bearing yet, do so. If you can't pry it out of the hub, that's probably where the pinch point is and why the hub won't come off the spindle. It's unlikely the large inner bearing is holding up the parade. I have had trouble getting the outer bearing out in the past. But once it finally was pried out, off came the drum. Just be glad you are not trying to remove a stuck REAR drum! Now, THAT'S a REAL bear!
