Sounds like the vac diaphram under the battery isn't being pulled to engage the front axel. Check it for tears. Also check that the little spring clip that holds the actuator onto the cable hasn't slipped (common) You can do this by carefully squeezing the servo and feeling the pull of the cable (you'll hear clicking in the front end) If both those are ok, start following the hose from the servo to the abs fix, then from the abs fix to the vac switch on the transfer case. Make sure there are no cracks or leaks. (When my 4wd had the same symptoms as yours I found that my vac hose from the servo has rubbed against the header and burned off, we ended up re-routing along the firewall then behind the brake booster...) Check these things and you will find your issue.
