Only seen it done on a lift with the tires still on. So you'll need room to pull the axle out. Basically, you push the axle into the knuckle while angling the inner portion out of the axle housing. Then you pull the stub back through the knuckle. Do opposite to reinstall. I guess also turning the tire makes it a little faster. Don't forget to remove the snap ring off the end of the stub shaft in the lockout.
Transfer the snap ring if it comes out of the diff. If not you'll have to search for it with a magnet.
Hell, we should get Mike to do it on video for us.
