Why are you removing 4x4 at all?
You can take the CV joints apart if you wish to run without the entire halfshaft. Pull the outer boot apart and disassemble the joint, leaving the outer section in the hub.
Or you can also take the 01+ hub/bearing setup. You do not need the bigger rotors but it is not a bad idea if you grab new/used knuckles and everything. A simple swap is just the hub/bearing unit and the axle shaft from a 00.5+ ranger, 95-01 explorer or 01-05 sport trac, they are all the same. IF you get the knuckles and larger rotors, be advised that some 15" wheels will not clear the calipers. I believe most aftermarket wheels will though.
With the long travel 4x4, you may actually wish to keep the selectable hubs up front. AVM or Rugged Ridge sells manual hubs for the PVH hubs. The only real downside is how they are held on, they can pop off with torque. One member here with the DBR kit uses zip-ties to hold the hubs on. Looks silly but it works. Plus when he breaks a CV joint he can unlock the hub and drive the truck.
