Thanks again, I knew there had to be a better / cheaper way.

This is what I've always used.

I have driven them out with a hammer and a large punch or drift. I have also knocked the inner race out, which causes the ball bearings to drop out. Then cut the outer race with a torch, then drive the race out with a hammer and punch. I have had to do that and I own a press. I have needed to remove and replace bearings from steering knuckles, that I flat could not find a way to hold the knuckle in the press solidly and have the bearing square with the press.

Atvs - remove with round punch and 2lb hammer working around. I ground down an old bearing to be smaller and use it to install new bearings.
Auto - had one stuck in solid axle and used long rod from the other side, of course the diff gears were already removed. We also torched the housing. Slide hammer is next best if diff gears are installed.
Have any pictures of what your working on?

I've replaced numerous on a Yamaha due to driving in swamps. Underwater is hard on them and the replacements just don't seem to last as long.
The yamaha doesn't have a grease zerk for the wheel bearing housing, just a few seals, so no way to fill that space with grease, making room for water to come in. The bearings themselves are sealed, but take that lightly. Hear are some things I've learned over replacements.
Seals easily come out with flathead screwdriver.
Clamp hub in solid vise or to solid surface.
Knock out old bearings from opposite side with punch and big hammer, youll only be able to punch the very inside edge but work around in circle and it'll come out easy.
Thoroughly clean inside with degreaser.
To install
I took an old bearing to grinder wheel and reduced it so it can be used to hammer in new bearing and its smaller so easily comes back out.
Use large socket to lightly tap in seals
On the machine, clean the surfaces the seals will touch very well. Then lubricate with grease so the seals slip on nicely.
Pack the housing with grease before you slide on the axle and pack as much as you can in once on. This keeps water out.
Tighten axle nut to spec, its pretty high.
