1977 power wagon doge What does it do when you switch the 4 wheel drive shifter to neutral?

On a 1977 Dodge Power Wagon, shifting the 4-wheel-drive shifter to neutral disengages the front driveshaft from the transfer case. This means the front wheels are no longer powered, and the vehicle is effectively rear-wheel drive only. It's crucial to do this before driving on dry pavement to avoid drivetrain damage.
