It sounds as if you have a vacuum solenoid problem. The 4x4/4x2 vacuum solenoids are attached to the upper RH side of the engine compartment, and alternately route vacuum to the vacuum motor which engages/disengages the center axle disconnect collar in the front axle assembly.They are grounded when activated, open circuit when deactivated.I would first of all make sure that you have power to them on the W/LB wire with ignition in run postion.If not then check fuse 23 (10amp) in the interior fuse panel.Disconnect the solenoids and measure their resitance should be between 50-100 ohms
If yours does not have the vacuum set up you have a bad new transfer case motor.
