    i'm not sure about this but i had an 01 that wouldnt go in 4x4 and when it did it wouldnt come out until it felt like it. i had to replace the 4x4 actuator. what a joke that was, plastic threaded into aluminum.

    Sounds like the encoder motor on the transfer case is sticking or starting to seize up.
