The following steps apply to all vehicles:
19. Remove the jack and fully
tighten the lug nuts in the order
shown. Refer to Wheel lug nut
torque specifications later in this
chapter for the proper lug nut
torque specification.
8–lug nut torque sequence
10–lug nut torque sequence
20. Stow the flat tire. Refer to Stowing the spare tire if the vehicle is
equipped with a spare tire carrier.
Note: Do not stow Harley-Davidson flat tire and wheel using the spare
tire winch mechanism; store the flat in the bed of the truck.
21. Stow the jack, jack handle and lug wrench. Make sure the jack is
securely fastened so it does not rattle when driving.
22. Unblock the wheels.

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 in the direction
specified on the Tire Changing Instructions located with the jack
hardware.
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 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 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. Repeat this tightness check procedure when servicing the spare tire
pressure (every six months, per Scheduled Maintenance Guide), or at
any time that the spare tire is disturbed through service of other
components.
6. If removed, install the spare tire lock (if equipped) into the bumper
drive tube with the spare tire lock key (if equipped) and jack handle.
WHEEL LUG NUT TORQUE SPECIFICATIONS
On vehicles equipped with single rear wheels, retighten the lug nuts to
the specified torque at 500 miles (800 km) after any wheel disturbance
(tire rotation, changing a flat tire, wheel removal, etc.).
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts
to the specified torque at 100 miles (160 km), and again at 500 miles
(800 km) of new vehicle operation and after any wheel disturbance (tire
rotation, changing a flat tire, wheel removal, etc.).

Bolt size Wheel lug nut torque*
lb.ft. N • m
M14 x 1.5 150 200
* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
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.
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
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.
INFORMATION CONTAINED ON THE TIRE SIDEWALL
Federal law requires tire manufacturers to place standardized
information on the sidewall of all tires. This information identifies and
describes the fundamental characteristics of the tire and also provides a
U.S. DOT Tire Identification Number for safety standard certification and
in case of a recall.

If the steering wanders or pulls, check for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper steering alignment
If any steering components are serviced or replaced, install new
fasteners (many are coated with thread adhesive or have prevailing
torque features which may not be re-used). Never re-use a bolt or nut.
Torque fasteners to specifications in Workshop Manual .
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle. The axle may
exhibit a slight noise or vibration in tight turns with low vehicle speed.
This is normal behavior and indicates the axle is working.
PREPARING TO DRIVE YOUR VEHICLE
Utility vehicles have a significantly higher rollover rate than
other types of vehicles.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a safety belt.
Your vehicle has larger tires and increased ground clearance, giving the
vehicle a higher center of gravity than a passenger car.
Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles are not
designed for cornering at speeds as high as passenger cars any more
than low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
