1.
Attach the spare tire lock key (A) to the
jack handle (B). 2. Fully insert the jack handle (with one
extension) through the bumper hole
and into the guide tube. The key and
lock will engage with a slight push and
counterclockwise turn. You will feel
some resistance when you turn the jack
handle assembly.
3. Turn the handle counterclockwise and
lower the spare tire until you can slide
the tire rearward and the cable is slack.
4. Remove the retainer through the center
of the wheel. If your vehicle is equipped
with a tether, perform the following
steps. 5.
Lift the spare tire on end to access the
tether attachment.
6. Use the lug wrench to remove the lug nut from the spare tire tether.
7. If not replacing the spare or flat tire to the underbody storage area, raise the
wheel retainer up into the installed
position.
8. Use the attached fastener strap (on the spare tire tether) to attach the
tether end to the winch retainer prior
to raising to the installed position.
Tire Change Procedure WARNINGS
When one of the front wheels is off
the ground, the transmission alone
will not prevent the vehicle from
moving or slipping off the jack, even if the
transmission is in park (P). To help prevent the vehicle from
moving when you change a tire, be
sure to place the transmission in park
(P), set the parking brake and block (in
both directions) the wheel that is
diagonally opposite (other side and end of
the vehicle) to the tire being changed. Never get underneath a vehicle that
is supported only by a jack. If the
vehicle slips off the jack, you or
someone else could be seriously injured.

WARNINGS
Do not attempt to change a tire on
the side of the vehicle close to
moving traffic. Pull far enough off the
road to avoid the danger of being hit when
operating the jack or changing the wheel. Always use the jack provided as
original equipment with your vehicle.
If using a jack other than the one
provided as original equipment with your
vehicle, make sure the jack capacity is
adequate for the vehicle weight, including
any vehicle cargo or modifications. Note:
Passengers should not remain in the
vehicle when the vehicle is being jacked.
Park on a level surface, set the parking
brake and activate the hazard flashers. 1.
Turn the engine off and block the wheel
that is diagonally opposite of the flat
tire using the wheel chock. Note: Lock
the manual hub on the wheel if the
vehicle is a 4x4.
2. Remove the jack, jack handle, lug wrench and spare tire from the
stowage locations.
3. Use the tip of the lug wrench to remove
any wheel trim.
4. Loosen each wheel lug nut ½ turn counterclockwise, but do not remove
them until the wheel is raised off the
ground. F-250 and F-350 Single Rear Wheel
Vehicles
1. Insert the hooked end of the jack
handle into the jack and use the handle
to slide the jack under the vehicle.
2. Position the jack according to the following guides: Front (4x2).

Jack at the specified locations to
avoid damage to the vehicle. Jacking the Vehicle 1. Turn the jack handle clockwise until
the wheel is completely off the ground
and high enough to install the spare
tire.
2. Remove the lug nuts with the lug wrench.
3. Replace the flat tire with the spare tire,
making sure the valve stem is facing
outward for all front wheels and single
rear wheel vehicles. If you are replacing
an inboard rear tire on dual rear wheel
vehicles, the valve stem must be facing
outward. If you are replacing the
outboard wheel, the valve stem must
be facing inward. Reinstall the lug nuts
until the wheel is snug against the hub.
Do not fully tighten the lug nuts until
the wheel has been lowered.
4. Lower the wheel by turning the jack handle counterclockwise.
5. Remove the jack and fully tighten the lug nuts in the order shown. See
Technical Specifications (page 299).
6. Stow the flat tire. See Stowing the flat or spare tire if the vehicle is equipped
with a spare tire carrier.
7. Stow the jack, jack handle and lug wrench. Make sure the jack is securely
fastened so it does not rattle when
driving.
8. Unblock the wheels.

When installing the wheel center
ornaments, make sure that the ornament
retention towers on the back side of the
ornament are aligned with the studs or lug
nuts. The retention towers are designed to
be installed over the studs or nuts and
retain to the flange on the lug nut. If the ornament retention towers are
aligned between the studs or lug nuts, the
ornament is improperly installed. This
improper installation may appear and
sound correct, but will not keep the
ornament on the vehicle. Ornaments
improperly installed in this manner will fall
off or become loose with minimal force or
impact.
F-350 Dual Rear Wheel, F-450 and
F-550 Vehicles

Jacking the Vehicle
1. Insert the jack handle into the pump
linkage.
2. Use an up-and-down motion with the jack handle to raise the wheel
completely off the ground.
Note: Hydraulic jacks are equipped with a
pressure release valve that prevents lifting
loads which exceed the jack's rated
capacity.
3. Remove the lug nuts with the lug wrench.
4. Replace the flat tire with the spare tire,
making sure the valve stem is facing
outward on all front an inboard rear
wheels. If you are replacing the
outboard wheel, the valve stem must
be facing inward. Reinstall the lug nuts
until the wheel is snug against the hub.
Do not fully tighten the lug nuts until
the wheel has been lowered.
5. Lower the wheel by slowly turning the release valve counterclockwise.
Opening the release valve slowly will
provide a more controlled rate of
descent.
6. Remove the jack and fully tighten the lug nuts in the order shown. See
Technical Specifications (page 299).
7. Stow the flat tire. See Stowing the flat or spare tire if the vehicle is equipped

1. Align the ornament with the lug nuts.
A is the clip and B is the flange. 2. Hold the ornament so that all of the
retention clips are sitting on the flange
of the lug nuts. 3. Use your hand or rubber mallet to tap
the ornament in a star pattern. There
should be an even gap between the
ornament and the wheel.
4. Be sure to install all the clips on the nuts over the flanges so that there is
an even gap all around and the
retention clips are fully seated. Stowing the Flat or Spare Tire
Note:
Failure to follow spare tire stowage
instructions may result in failure of cable or
loss of spare tire.
Note: If you are stowing a tire that requires
reattaching it to the vehicle with a tether,
perform these steps first, then proceed with
the following steps.
1. Place the tire on end with the valve stem facing toward the front of the
vehicle.
2. Place the tether into the bolt holes in the wheel and attach the lug nut using
the lug wrench.

3. Lay the tire on the ground with the
valve stem facing up.
4. Slide the wheel partially under the vehicle and install the retainer through
the wheel center. Pull on the cable to
align the components at the end of the
cable.
5. Turn the jack handle clockwise until the tire is raised to its stowed position
underneath the vehicle. The effort to
turn the jack handle increases
significantly and the spare tire carrier
ratchets or slips when the tire is raised to the maximum tightness. Tighten to
the best of your ability, to the point
where the ratchet/slip occurs, if
possible. The spare tire carrier will not
allow you to overtighten. If the spare
tire carrier ratchets or slips with little
effort, take the vehicle to your
authorized dealer for assistance at your
earliest convenience.
6. Check that the tire lies flat against the frame and is properly tightened. Try to
push or pull, then turn the tire to be
sure it will not move. Loosen and
retighten, if necessary. Failure to
properly stow the spare tire may result
in failure of the winch cable and loss
of the tire.
7. Repeat this tightness check procedure
when servicing the spare tire pressure
(every six months, per scheduled
maintenance information), or at any
time that the spare tire is disturbed
through service of other components.
8. If removed, install the spare tire lock into the bumper drive tube with the
spare tire lock key and jack handle.
