2 long screw drivers or pry bars. Just have a friend help you.
It will pull right off. If you start hammering on things, it will put flat spots on the bearing races.
I have never put any kind of dent or flat spot on the races. I am hitting more down than out. Just to get it moving, I do pry it on the ring gear side though. I can't imagine how ass wild you would have to get on those bearings to put a flat spot on them. They are very stout and HARD.
