In a nutshell: pull the front tires, hubs, lower ball joint, halfshafts, front crossmember, driveshaft, drop the diff, pull the old jack shafts and reverse steps for install. One thing to note is the steering linkage does not have to be pulled for the diff drop, contrary to what the guide instructs.
I dropped the diff last week and it took a three hours just to drop it (not reinstall). Give yourself plenty of time, it's a long process.
