Just go get a new axle from s salvage or part out. Gonna be much cheaper and faster to swap the whole axle.
On a side note....do you have joint axle shafts or CV axle shafts?
If you need to drive it and have the u joint shafts....remove the joint and use only the outer stub shafts. The lack of inner shafts will keep anything from moving in the housing (with driveshaft disconnected of course). But the outrrz have to be installed to keep the unit bearings together
