Real axle removal, Step by step Options

[zonedoubt]

I know there's lots of posts with tips, hints, opinions, etc about rear axle removal. However I haven't found anything with a step by step method that suits my situation.

I've been trying to remove the axle from under the car so I can service the inner CV joint. I backed out the outer CV bolts but couldn't get it apart with the limited amount of space under there. So removing the big ol' castellated nut seems like my next option.

Let me know if I got the steps in the correct order so I don't break something...

1) Rear wheels on the ground, blocked, chocked, braked.
2) Breaker bar or impact wrench to remove 30mm castellated nut.
3) Put the nut on reverse so there's a better surface to hammer out the stub axle without damaging the threads.
4) Hammer out the stub using a brass punch (wheels on ground or jacked up?)
5) Remove the stub/CV/axle from underneath the car

Well, assuming one still has brakes, you could get a helper (IMG:style_emoticons/default/beerchug.gif) to firmly put his/her foot on the brake pedal. This should provide enough torque to remove the nut.

I'd be rather concerned about putting that much torque on a car that was up in the air, but it can be done. Maybe lower the car onto large flat blocks or something like that before applying torque (and brake).
