    What is moving and what is not? Once you figure that out you found where your problem lies. Don't be afraid to open the gearbox up if necessary - nothing will spring out. Use the exploded views that came with the truck.

    Check for a spun wheel hex then make sure your wheel to outdrive connection is solid. If so check for loose or contaminated clutch. If that is ok then you have to open the transmission and check for stripped gears. If they are OK then you may have a broken layshaft pin.

    One step at a time---
    Take the gear cover off and see if the spur gear is spinning?
    After that, are the axels turning?

    Process of elimination...

    Good luck
