The front axle is vacuum actuated. You need to get to the actuator (under the battery) and see if it is working properly. If it is not receiving vacuum when you have the transfer case in 4HI or 4LO (& engine running), then you have to investigate the vacuum supply to the transfer case, the vacuum switch on the transfer case, as well as the vacuum supply from the switch on the transfer case to the front axle actuator.
