Why go through the trouble of pulling the shafts and then not changing the U-joint yourself? A hammer, pliers, and a 3/4" socket and the u-joint is easily changed.
If you have done driveshaft joints like you said then you can do the axle. The hardest part will be getting the hub unit/shafts out. Use a bolt like said above and wedge it between the knuckle and one of the u joint ears and turn the steering wheel.
