Inspect connector C305 and C305B at the body pass through for corrosion, if no corrosion is found suspect the differential clutch pump actuator check valve as the possible cause. Check this first.

How did you check the clutch pump actuator?Did you test the circuit?Did you find any bent terminals or corroded terminals at the pass throught at C305 that is located on the floor to the rear of the driver's seat?This is common on these. Only other fix is a PCM, AWD gets its input from the PCM. Before you start replacing unnecessary parts post back with what you tested, circuits, any data from a scan tool, etc.
