    The most common cause for this is a vacuum leak or the vacuum switch on top of the transfer case. Vacuum actuated front axle! Switch is NAPA part # 730169.. Tough to change without a lift.! That will fix 95% of them i have found,, fixed mine as well.. Possible actuator under battery tray but less likely.
