• Do not operate the vehicle with a low power steering pump fluid level
(below the FULL COLD mark on the dipstick).
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
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.

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: If your vehicle is equipped with 20” tires, do not stow the 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 authorized
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 information),
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.).

* 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.
JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; doing so may
damage the catalytic converter.
