I'm not quite sure I am understanding your question. Do you have the hub off the car? If you do then you should be able to take a screw driver and get the seal out. You will more than likely tear it up when you remove it but they are cheap. Once the seal is out the bearing should just press out. Use a drift and hammer if it needs some persuasion. Do not damage the area where the bearing and seal fits inside the hub. Another way would be to just use the drift and drive the bearing and seal out at the same time.

Take the lock nut off, remove the outer bearing, then screw the nut back on. grab the rotor by the outer edge an wiggle the nut past the outer race, then pull briskly out and down. You may have to repeat once or twice but the inner bearing will be left hanging on the spindle along with the undamaged grease seal.

That's a very unique way of removing the rear bearing. I would have never thought of doing it that way. I always use the hammer and punch method.

In order to get the inner wheel bearing out, you will need to first prise out the hub seal. Snap-on makes a great seal removal tool for this but in a pinch you can take a small chisel and a light hammer and deform the edge of the seal enough to pry it out from the hub. You can then remove the inner bearing. Remember when you reinstall the new hub seal that you need to tap it down EVENLY and GENTLY until it bottoms out. I recommend a seal installer tool (also can be had from Snap-on) but you can also use a socket that is the same diameter as the seal and tap it in. You'll hear it bottom out against the hub and when you hear it, STOP hammering or else you'll bend the inner lip of the seal in and it will leak grease. Good luck.
