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.

TECHNICAL SPECIFICATIONS

Wheel Lug Nut Torque Specifications

WARNING

When a wheel is installed, always remove any corrosion, dirt or foreign materials
present on the mounting surfaces of the wheel or the surface of the wheel hub,
brake drum or brake disc that contacts the wheel. Make sure that any fasteners

that attach the rotor to the hub are secured so they do not interfere with the mounting
surfaces of 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.

*

Torque specifications are for nut and bolt threads free of dirt and rust. Use only Ford

recommended replacement fasteners.

On vehicles equipped with single rear wheels, retighten the lug nuts to the specified torque
at 100 miles (160 kilometers) after any wheel disturbance (such as tire rotation, changing
a flat tire, wheel removal).

On vehicles equipped with dual rear wheels, retighten the wheel lug nuts to the specified
torque at 100 miles (160 kilometers), and again at 500 miles (800 kilometers) of new
vehicle operation and after any wheel disturbance (such as tire rotation, changing a flat
tire, wheel removal).

It is important to follow the proper wheel mounting and lug nut torque procedures.

On all two-piece flat wheel nuts, apply one drop of motor oil between the flat washer
and the nut. Do not apply motor oil to the wheel nut threads or the wheel stud threads.
