Remove C-washer or snap ring from half shaft groove.
Remove spacers (three thrust washers) from shaft.
Remove cam assembly. Pull to remove.
If front disc brake hub and rotor and front wheel spindle (3105) are to be removed, refer to Wheel Grease Seal and Bearing, Front Replacement and Repacking, in the Disassembly and Assembly portion of this section.
Installation
Align the fixed cam retaining key on the cam assembly (garter spring inboard) with the keyway on the spindle. Firmly press the cam assembly on the wheel retainer nut. CAUTION: Improper sequence of three-piece thrust washers will result in excessive wear of assembly.
Install three-piece thrust washer set (first metal, second plastic, third splined) and snap ring. It may be necessary to push the axle outboard from backside of knuckle. Be sure snap ring is seated in groove properly. CAUTION: Rotate moving cam stop (use any one of three) to the one o'clock position in relationship to the fixed cam retaining key. CAUTION: Do not force body assembly into front disc brake hub on rotor if body assembly will not fit. Recheck alignment of all components.
NOTE: The hubs should not be packed with grease. Too much grease will damage the hubs and prevent proper operation.
Install body assembly into vehicle front disc brake hub and rotor by lining up the three legs outside the hublock body with the three pockets in the cam assembly.
Make sure body assembly is in far enough to see groove in rotor tube. Install large lock ring into groove of hub. Be sure lock ring is correctly seated.
Install cap to body assembly. Install three capscrews and tighten to 4-6 Nm (35-53 lb-in).

SOURCE: Brake rotor replacement
you should only have to take off the tire and the calipers, and the caliper bracket, there is no hub on the front wheels. there should be 2 bolts holding on the caliper bracket, usually with a big allen screw. they may be stuck so use a hammer to tap them loose. good luck
SOURCE: Trying to remove rotor and hub assembly off my 97 dodge 2500 4x4
if you have twenty years experience rpm northwes why wouldnt you know that a dodge has several more steps to pull off a rotor. It is a difficult job especially if it had never been taken off before.
SOURCE: removing the front brake rotor from the hub housing
You need to take the rotor/hub off the spindle.So you'll need to remove the wheel bearings in order for it to come off. Once off theres bolts in the back of the rotors bolted to the hub.
SOURCE: cannot get the hub off to replace rotors
the rotors should be on the hub behind the wheel... you will have to remove the brake caliper and it should just pull off... may be a few clips on the wheel stud
SOURCE: 1993 F150 4x4 w/ auto locking hubs - rotor removal
There are some special 4 tooth and hex sockets for removing the nuts inside the hubs of the truck.
YOu can find these at NAPA or maybe AutoZone or Advance. I would go to NAPA because they more than likely have it and also know something about repairing this assembly.
Ford uses Dana front end parts and NAPA has original Dana parts in stock... so it is as good as or better than original and they would have the tool for it.
Be careful and follow the procedure exactly for putting the front hubs back together.
YOU CAN RUIN THE FRONT END OF THE TRUCK IF YOU DO NOT PERFORM THIS SERVICE CORRECTLY.
And trust me... many of the idiots working in repair garages do not know how to do these older 4x4 hubs either... ask someone and read the books for the right procedure... some of the older mechanics may show you how to do it. Ask
