Yeah, the proper tool is very large and heavy, and looks more suited to working on semis, if not quite locomotoves.

I got one a long time ago on eBay, some sort of military surplus part. Looks about like this:


You put it on 3 studs, take the castle nut off, reverse it, and screw it back on leaving a small gap between it and the drum so it can support the end of the axle shaft, snug it up, then use a hammer to both spin the arms to tighten it more, and pound on the end of the shaft to send some shock waves through that axle/hub interface.

Some PBLaster soaking into the interface is probably a good idea as well. And perhaps some time as well, when I first got my car it had spent 17 years sitting in a carport, after one of the rear brakes had a sticky wheel cylinder that stuck the brake on. Overheated, then left to sit. Stuck as tight as can be. I pounded and pounded with a big hammer, got irate, started to fling tools and curse words, and finally had to just walk off and do something else for a while, leaving the puller on there as tight as a violin string.

And about an hour later, from inside the house, I head a very loud *BANG*, about like a pistol going off, went outside and the drum had popped off and flown about 4 feet (another reason to reverse that castle nut and only leave it a little gap).
