What I did on mine was this. I had removed everything I could, spider gears and axles. I then took a really long piece of rebar and carefully inserted it in the axle tube till it was pressing on the back side of the bearing on the opposite side of the axle. I whacked it with a hammer and I think the bearing came out in one hit. So try that with a piece of rebar or long wooden dowel or something similair. If using rebar be careful so you don't damage or scratch anything up on the inside.
