On the front axle, on the passenger side there is a vacc pot that lockes the axle. This pot can go bad, you can lose vaccum. Ensure you have vaccum there and the post is operating correctly. The vaccum just moves a cog over the axle ends locking it and in turn you get 4wd. Check here first and let us know. Curt
