Has anyone rebuilt their axles?

[Jamesp]

I jacked up all 4 corners to change the transmission oil (Swepco 201) and noticed the right rear outer CV boot had deposited its grease on the inside of the right rear wheel. I washed the car on Sunday including the inside of the wheels, and it wasn't there then. so I checked the other side, lo and behold, it's just starting to let its grease out too. :ah: I have some economically friendly (cheap -$34 each on clearance, shipping included) Chinese replacement axles to get me back on the road, but would like to do a quality rebuild on the originals and swap them back in.
