Have done it a few times. This guide is complete. Make sure you have 54mm axle nut socket, torque wrench, snap ring pliers, lots of grease for packing bearings and birf, brass drift/punch, anti-seize, pull scal/fish scale, one M8x1.25 bolt (check guide regarding putting snap ring back on, pretty sure that is the size you will want), use the FSM suggestions on shim heights, I don't remember but pretty sure 4crawler references the correct shim pattern.
If your new hub is greased leave it be, if not be prepared for some patience. There is a YouTube out there on cleaning and regressing the hub. It's a bit of a pain.
That's the most important things off the top.of my head. Good luck.
