I'll admit it, I'm a novice - so go easy

I've got a 1971 f100 2WD. When I remove the wheel (5 lug nuts) all I see is drum, and 5 studs. Can I pop the drum off with a gear puller? Doesn't seem to want to budge with gentle hammer strikes.
Or... must I disassemble the differential, pull the axle, etc.?
