Great thread. I use another aproach for bearing removal. It has served me well for over 30 years. It's quick and easy.
Remove the guts of the bearing including the balls. It's very easy and usually can be disassembled in a minute with a drift and hammer.
Once you are down to the outer race that is pressed in the arm, use a MIG welder and make several passes inside the race in the same location that the balls were running. Let it cool. The bearing will shrink from the welding process and will now almost fall out. At the minimum, a drift and hammer tapping on the welds will slide it right out. If it doesn't, make another pass.
This works even easier on the front bearings. One pass with the welder and the races will fall out once cool. And no, it doesn't overheat the base metal, the heat absorbs quickly into the base mass.
I don't have a picture of the rear but attached is this method on the front hubs.
