To lessen the risk of
personal injury, do not put
any part of your body under the
vehicle while changing a tire. Do
not start the engine when your
vehicle is on the jack. The jack is
only meant for changing the tire.
•Never use the front or rear
differential as a jacking point.
5. Remove the lug nuts with the lug wrench.
6. Replace the flat tire with the spare tire, making sure the valve stem is
facing outward. Reinstall the lug nuts, cone side in, until the wheel is
snug against the hub. Do not fully tighten the lug nuts until the wheel
has been lowered.
7. Lower the wheel by turning the jack handle counterclockwise.
8. Remove the jack and fully tighten
the lug nuts in the order shown.
Refer toWheel lug nut torque
specificationslater in this chapter
for the proper lug nut torque
specification.
Stowing the flat/spare tire
Note:Failure to follow spare tire stowage instructions may result in
failure of cable or loss of spare tire.
1. Lay the tire on the ground with the valve stem facing up, toward the
vehicle.
2. 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.
3. Turn the lug wrench 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 dealer for
assistance at your earliest convenience.
4. 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.
5. If your vehicle is equipped with a spare tire lock and key, be sure to
install the spare tire lock into the bumper drive tube with the spare tire
lock key and jack handle.
6. Repeat this tightness check procedure when servicing the spare tire
pressure (every six months, perScheduled Maintenance Guide),or at
any time that the spare tire is disturbed through service of other
components.
Re-stowing the jack and tools
1. Unblock the wheels.
2. Replace beauty cap, stow the jack and tools in their respective
locations, making sure they are fully secured so they do not rattle when
you drive.
WHEEL LUG NUT TORQUE SPECIFICATIONS
Retighten the lug nuts to the specified torque at 50–100 miles (80–160
km) after any wheel disturbance (rotation, flat tire, wheel removal, etc.).
Lug nut socket

Lug nut socket size:

Bolt size:12x20100 135
* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
When a wheel is installed, always remove any corrosion, dirt and
foreign materials present on the mounting surfaces of the wheel
and the surface of the front disc brake hub and rotor that contacts the
wheel. Installing wheels without correct metal-to-metal contact at the
wheel mounting surfaces can cause the wheel nuts to loosen and the
wheel to come off while the vehicle is in motion, resulting in loss of
control.
