    Are you sure its not going into 4 wheel drive? Manual transfercase? You should just shift it in, and its in. There is a front axel disconect. Check to make sure its working.

    It has to be the front axel disconnect. If you put it in 4 hi, and its STILL not in 4 hi, the only other thing I can think of it being is a broken transfercase. And you would be able to hear that.

    The hubs on your truck are automatic (ADD = Automatic Differential Disconect). There is an actuator in the front that connects the driver and passenger side together. If its not working, your 4x4 light will not illuminate, and it will feel as if you are not in 4 wheel drive.
