STEERING
To help prevent damage to the power
steering system:
•
Never hold the steering wheel at its
furthest turning points (until it stops)
for more than three to five seconds
when the engine is running.
• Do not operate the vehicle with a low
power steering pump fluid level (below
the MIN mark on the reservoir).
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.
• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
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 vehicle 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.
A high crown in the road or high crosswinds
may also make the steering seem to
wander or pull.

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.

1. Slide the notched end of the jack
handle over the release valve and use
the handle to slide the jack under the
vehicle. Make sure the valve is closed
by turning it clockwise.
2. Position the jack according to the following guides:

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 290).
7. Stow the flat tire. See Stowing the flat or spare tire if the vehicle is equipped
with a spare tire carrier. 8. Stow the jack, jack handle and lug
wrench. Make sure the jack is securely
fastened so it does not rattle when
driving.
9. Unblock the wheels. 8-lug nut torque sequence

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. lbf.ft (Nm)

* 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. 290
