    Cannot be nothing other than a guess in this forum. Recommend you get it to a good honest technician on that one. Here are some the things that are possibly causing problem. Not a extremly tought diagnosis for many techs.

    Axle Actuator Ground
    Front Axle Actuator Power
    Front Axle Actuator Wiring
    Front Differential
    Transfer Case Control Module (TCCM)
    Transfer Case Control Module (TCCM) Connector
