How do you remove the front wheel hub from the steering knuckle on a 1993 Toyota Camry?

With the wheel on the ground remove the large axle nut which is very difficult with hand tools, I had to use an air impact on mine. After removing the nut, knock the axle shaft back just a little bit. Then jack up the car remove tire, remove brake caliper, and remove brake rotor. Then you should be able to remove the hub. You may have to hit the axle back a couple of more times but that's how I got mine off.
