    Since it runs ok in 2 wd the issiue is probably in the transfer case. It could be anyones guess as to whats happened inside the t-case. Wont know until its pulled apart and looked at by a professional.
    I would probably leave the truck at home for the trip, if somethings loose in the t-case you dont want it getting into the rear drive section and cause more damage.

    Could be the transfer case.
