As for cutting the shaft,,thats the easy part. The big problem ppl seem to have is snapping off the tapping tool in the threads they are making and or drilling straight(get the IRO jig for drilling if you can't drill very well) .. Just take your time and use lots of oil on the tap and back the tap out after about half turns to clear the cuttings off the teeth of the tapping tool. Then cut some more threads, back it out and so on until you have it.. good luck

I will add, that the taps from IronRock are tapered and drilled hole needs to be longer than necessary to accommodate taper. I suppose a bottoming tap would be better suited.

I'm debating on how I want to do this. I really to take the t case out to do it. I've seen tutorial vids where people measure it off and use an angle grinder with it spinning in first gear. So it act's kind of like a lathe in a sorts. Helps to get a straighter and faster cut.
Have done two hacks. Second one I tried cutting with engine off, did not work as well.
Wear a face shield and long clothes, the sparks fly!
The other way to turn the shaft and cut, is to lift one front wheel off ground and have a friend rotate wheel. Place transfer case in 4WD mode, not sure if Low of High range would work better.
And of course properly support vehicle and chock wheels.

Cutoff worked fine for me with engine running. I ate some drill bits until I got cutting oil then that was cake too. Tapping was no problem at all with the oil
