Instead of using a jack to push it out, I used a ratchet strap to pull it in. Turn the bars backwards, make sure cups and bearings and everything is installed tightly. I just set this up for the picture. Put an old hub on the front, wrapped the strap around the seat tube and cranked it down slowly. Worked like a charm. I've not seen it done like this before, so I'm taking credit, but I'm sure someone has in the past.
