No need to heat. Here is what I do:
Red Rider, you are correct that there is no lip to use a blind puller, nor can you just start driving with a drift. The key is to get one bearing separated first. Knock out the dust seal on one of the bearings so that you can see the cage holding the balls. Use a small punch to knock out the cage (it is easy to do, but will come out in lots of pieces). Scoot the balls all together to one side of the bearing and this will allow you to pull the inner race out. With the inner race out, the balls and pieces of the cage will be gone. Now the center spacer tube can be pulled out and you're in business. Either a puller on the outer race that is left, or a drift from the other side can knock the bearings out.
