Ford F series Owner's Manual page 240

When the transfer case is in the N (Neutral)
position, the engine and transmission are
disconnected from the rest of the driveline.
Therefore, the vehicle is free to roll even if the
automatic transmission is in P (Park) or the
manual transmission is in gear.
Do not leave the vehicle unattended with
the transfer case in the N (Neutral)
position. Always set the parking brake
fully and turn off the ignition when
leaving the vehicle.
On F-Super Duty vehicles, the parking brake is
on the transmission. Therefore, the vehicle will
not be prevented from moving when a rear
wheel is lifted, even if the vehicle is in Park and
the parking brake is applied. Be sure to block
both directions of the wheel that is diagonally
opposite to the wheel that is being lifted.
If the vehicle slips off the jack, you or
someone else could be seriously injured.
2. Get out the spare tire and jack.
The jack and lug wrench are stowed under the
hood on the right front fender inner panel, and
the jack handle is on the radiator support.
