3. Drain the diesel fuel conditioner
module. Turn the drain plug
counterclockwise until it stops. Do not
use any tools to loosen the drain plug.
Drain the filter, approximately 0.5 gal
(2 L), into an appropriate container. Do
not re-use the fuel drained from the
module. 4. Disconnect the electrical connector.
5. Fully loosen the bolts securing the
lower portion of the diesel fuel
conditioner module housing.
Note: Do not fully remove the bolts from
the lower portion of the diesel fuel
conditioner module housing.

7. Slide the filter element toward the
drain plug to disengage the securing
clips.
Installation
1. Slide the filter element into the housing
and fully engage the securing clips.
2. Install the lower portion of the housing.
Tighten the bolts until you feel a strong
resistance. Maximum torque 7 lb.ft
(9 Nm).
3. Connect the electrical connector.
4. Tighten the drain plug, turn it clockwise
until it stops and you feel a strong
resistance. Do not use any tools to
tighten the drain plug.
5. Switch the ignition on for 30 seconds and then switch the ignition off. Repeat
this operation six times in a row to
purge any trapped air from the fuel
system. Engine-mounted Fuel Filter
Although the fuel system is not fully
pressurized when the vehicle is off, some
residual pressure may remain in the fuel
system since it can take some time for the
pressure to completely bleed off.
Therefore, we recommend you place an
absorbent cloth below the filter connectors
to absorb any fuel that may drain.
The engine-mounted fuel filter is a plastic
disposable cartridge.
Removal
1.
Disconnect the fuel lines by squeezing
the connector tabs and pulling the lines
straight off.

position neutral (N) or park (P). Turn
the engine off.
3. Clean any dirt from around the axle filler plug.
4. Remove the filler plug and inspect the lubricant level. It should be at the
bottom of the filler plug opening.
5. Add lubricant, if necessary, through the
filler plug opening.
6. Clean and install the filler plug securely.
Changing the Fluid
Note: Drain the rear axle while the lubricant
is warm.
1. Park your vehicle on level ground.
2. Set the parking brake and shift into position neutral (N) or park (P). Turn
the engine off.
3. Clean any dirt from around the axle filler and drain plugs.
4. Remove the filler and drain plugs. Drain
the lubricant into a suitable container.

in a responsible manner following your
local authorized standards.
5. Clean and install the drain plug securely.
6. Add lubricant through the filler plug opening.
7. Clean and install the filler plug securely.
SPRING U-BOLT CHECK
Check and tighten the U-bolt nuts after
your vehicle has been operated under load
for 1,000 mi (1,600 km) or six months,
whichever occurs first. Thereafter, install new U-bolt nuts and
washers every
36,000 mi (58,000 km).
Check and tighten the U-bolt nuts with
your vehicle at curb height and unloaded.
Inspect the U-bolt threads for rust and
debris. Clean the threads if contaminated.

The tires on your vehicle have all-weather
treads to provide traction in rain and snow.
However, in some climates, you may need
to use snow tires and cables. If you need
to use cables, it is recommended that steel
wheels (of the same size and
specifications) be used, as cables may chip
aluminum wheels.
Note:
The suspension insulation and
bumpers help prevent vehicle damage. Do
not remove these components from your
vehicle when using snow tires and chains.
Follow these guidelines when using snow
tires and chains:
• If possible, avoid fully loading your
vehicle.
• Use only SAE Class S chains.
• Install chains securely, verifying that
the chains do not touch any wiring,
brake lines or fuel lines.
• Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does
not work, remove the chains to prevent
damage to your vehicle.
• Remove the tire chains when they are
no longer needed. Do not use tire
chains on dry roads.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.
CHANGING A ROAD WHEEL
If you get a flat tire while driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road. Tire Change Procedure WARNINGS
When one of the front wheels is off
the ground, the transmission alone
will not prevent the vehicle from
moving or slipping off the jack, even if the
transmission is in park (P). To help prevent the vehicle from
moving when you change a tire, be
sure to place the transmission in park
(P), set the parking brake and block (in
both directions) the wheel that is
diagonally opposite (other side and end of
the vehicle) to the tire being changed. Never get underneath a vehicle that
is supported only by a jack. If the
vehicle slips off the jack, you or
someone else could be seriously injured. Do not attempt to change a tire on
the side of the vehicle close to
moving traffic. Pull far enough off the
road to avoid the danger of being hit when
operating the jack or changing the wheel. Note:
Passengers should not remain in the
vehicle when the vehicle is being jacked.
Park on a level surface, set the parking
brake and activate the hazard flashers. 1.
Turn the engine off and block the wheel
that is diagonally opposite of the flat
tire using a wheel chock.

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. lb.ft (Nm)
Bolt size
450–500 lb.ft (610–678 Nm)
M22 x 1.5
* 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 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.

AUDIO INPUT JACK
WARNINGS
Driving while distracted can result in
loss of vehicle control, crash and
injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the safe
operation of your vehicle. We recommend
against the use of any hand-held device
while driving and encourage the use of
voice-operated systems when possible.
Make sure you are aware of all applicable
local laws that may affect the use of
electronic devices while driving. For safety reasons, do not connect
or adjust the settings on your
portable music player while your
vehicle is moving. Store the portable music player in a
secure location, such as the center
console or the glove box, when your
vehicle is moving. Hard objects may
become projectiles in a collision or sudden
stop, which may increase the risk of serious
injury. The audio extension cable must be
long enough to allow the portable music
player to be safely stored while your
vehicle is moving. The auxiliary input jack allows you to
connect and play music from your portable
music player through your vehicle speakers.
You can use any portable music player
designed for use with headphones. Your
audio extension cable must have male
1/8th-inch (3.5 millimeter) connectors at
each end.
1. Make sure your vehicle, radio and
portable music player are turned off
and the transmission is in position P.
2. Plug the extension cable from the portable music player into the AIJ.
3. Turn on the radio. Select either a tuned
FM station or a CD.
4. Adjust the volume as desired.
5. Turn on your portable music player and
adjust its volume to half its maximum
level.
6. Press
AUX until LINE or LINE IN
appears in the display. You should hear
music from your device even if it is low.
7. Adjust the volume on your portable music player until it reaches the volume
level of the FM station or CD. Do this
by switching back and forth between
the AUX and FM or CD controls.
