Drive unit will be in overrun mode in forward or reverse if no rear wheel slip Is present. Locked in 2wd is a problem. If connector is disconnected, check voltage in chassis side lead for at least 11 volts with 4wd switch in on position. Should be zero volts in 2wd. If opposite, look at switch wiring. Check coil resistance to spec for your unit. Probably around 20-22 ohms. Pull unit for component inspection if all is well electrically. With cover off, you should be able to rotate roller cage assembly to cam the rollers on the ramps to lock ring gear to drive hubs. Rotate hub to verify engagement. Inspect torsion spring, pin, and retainer, armature plate, sprag rollers, roller cage, and surfaces on output drive hubs and ring gear for wear or damage. Keep rollers and cage in the ring gear to retain assembly when pulling ring gear. Devise a sleeve and clamping system to slide roller assembly into to prevent rollers going all over the place. Wrap plastic with rubber bands, piston ring compressor, or similar method should work. Repair / replace as necessary. Not as difficult as it may sound. Keep components clean. Take to a professional if not comfortable doing yourself.

This may help. . . or overwhelm.
