GENERAL INFORMATION
WARNING
Exceeding these ratings by
overloading can cause component
failure resulting in property damage,
personal injury or death. Fluid Temperature
If the operating temperature exceeds
250°F (121°C), the rate of axle lubrication
oxidation increases and shortens the life
of the lubricant and seals, requiring axle
lubrication changes to become more
frequent to preserve the axle. Do not
consistently run extreme pressure (EP)
lubricants above
250°F (121°C).
Axle Conversions WARNING
When operating a loaded vehicle, the
driver must keep all adjustable axles
on the ground at all times, supporting
their share of the vehicle ’s load. Failure to
do so can overload other axles, tires,
wheels, springs, steering components,
brakes and frames, resulting in early
component failure, loss of vehicle control,
possible property damage and personal
injury. We do not recommend, or approve,
performing axle conversions. However, we
understand that, on occasion, others install
aftermarket add-on axles on the truck
chassis that allow operator control for
weight transfer from other axles (such as
air lift axles). LIMITED SLIP DIFFERENTIAL
(If Equipped) WARNING
If both wheels are not raised off the
ground, the one wheel that is not
raised may pull the vehicle off its
support, possibly resulting in personal
injury. This axle provides added traction on
slippery surfaces, particularly when one
wheel is on a poor traction surface. Under
normal conditions, the limited-slip axle
functions like a standard rear axle. The axle
may exhibit a slight noise or vibration
during tight turns with low vehicle speed.
This is normal behavior and indicates the
axle is working.
Both wheels must be raised off the ground
should it be necessary to operate one
wheel with your vehicle stationary.
ELECTRONIC LOCKING
DIFFERENTIAL
(If Equipped)
Driver-Controlled Locking
Differential
Note: Never use the differential lock at
vehicle speeds above
25 mph (40 km/h).
Some drive axles have a driver-controlled
differential lock. The differential lock can
lock or unlock the differential when your
vehicle is moving or stopped. When extra
traction is required, the differential lock
provides full power to both wheels.
When you lock the differential, your
vehicle ’s turning radius increases
(under-steer).
Take care to avoid sudden accelerations
when both drive wheels are on a slippery
surface.

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.
Operating the steering system excessively
at an elevated engine RPM (>1200 rpm)
for more than 2 minutes can result in
steering system damage from overheating.
Move the steering wheel to the full left
position then full right position at idle
speed, or stop using the system for 2
minutes to allow the system to cool down.
If the power steering system exhibits heavy
or uneven efforts, check for the following
before seeking service from your dealer:
• An improperly inflated tire.
• Overloading of front suspension.
• Uneven vehicle loading.
• Binding suspension components. If the power steering system wanders or
pulls, check for:
•
An improperly inflated tire.
• Uneven vehicle loading.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
• High crosswinds.
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.

VEHICLE INSPECTION
INFORMATION
To make sure your vehicle is ready to
operate, conduct a pre-trip inspection at
the beginning of each work period. Follow
the steps listed in this section to verify a
proper vehicle inspection procedure.
WARNINGS
Exercise great caution when working
on a vehicle equipped with an
automatic fan clutch. The fan starts
in motion only after the engine coolant
reaches a predetermined temperature or
the refrigerant pressure (if equipped with
air conditioning) reaches a predetermined
setting. The fan starts at this point with no
advance warning. Never reach near, or
permit objects to protrude into, the fan
blade radius while the engine is running as
this could result in vehicle damage,
personal injury or death. WARNINGS
Do not operate the vehicle if any
suspension conditions listed in the
following charts are evident. Loss of
steering or suspension could result in
property damage, personal injury or death. If a wheel must be changed, obtain
expert tire service help. Mounting and
un-mounting of tires should only be
performed by a qualified technician using
necessary safety procedures and
equipment, otherwise the result could be
property damage, personal injury or death. Note:
Always make sure you apply the
parking brake before starting the engine. Engine compartment (with engine off)
Use the dipstick to verify the oil level is in the proper operating
range. See Engine Oil Dipstick (page 185).
Engine oil
Look through the plastic reservoir and verify the coolant level
is within the proper operating range. Do not remove the
pressure cap until the coolant has cooled. See
Engine
Coolant Check (page 189).
Engine coolant
Verify that the fluid level is in the proper operating range. See

To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.
Only use fluid that meets Ford
specifications. See Capacities and
Specifications (page 252).
POWER STEERING FLUID
CHECK
Check the power steering fluid. See
Scheduled Maintenance
(page 316). If
adding fluid is necessary, use only
MERCON LV ATF
Check the fluid level when it is at ambient
temperature.
1. Check the fluid level in the reservoir. It should be between the MIN and MAX
range. Do not add fluid if the level is
within this range.
2. If the fluid level is low, add fluid to bring
the fluid level up to between the MIN
and MAX range.
3. Switch the engine on. 4.
While the engine idles, turn the steering
wheel left and right several times.
5. Switch the engine off.
6. Recheck the fluid level in the reservoir. Do not add fluid if the level is between
the MIN and MAX range.
7. If the fluid is low, add the proper type of fluid in small amounts, continuously
checking the level until it is between
the MIN and MAX range. See
Capacities and Specifications (page
258). Be sure to put the cap back on the
reservoir.
WASHER FLUID CHECK WARNING
If you operate your vehicle in
temperatures below 40°F (5°C), use
washer fluid with antifreeze
protection. Failure to use washer fluid with
antifreeze protection in cold weather could
result in impaired windshield vision and
increase the risk of injury or accident. Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See
Capacities and
Specifications (page 252).
State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle ’s paint finish, wiper blades or
washer system.

•
Maintaining proper steering gear and
power steering pump lubricant levels.
• Checking steering column joint bolts
and steering linkage, particularly for
body-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, check
steering column joint bolt tightness every
60,000 mi (96,000 km) or annually,
whichever occurs first. Do not overtighten
the bolts.
Hydraulic System
Whenever draining and refilling the power
steering's hydraulic system for any reason,
bleed air from the system before returning
the vehicle to service. Failure to bleed the
hydraulic system properly can result in
degradation of power system performance.
Consult an authorized dealer who is aware
of the proper procedures for filling and
bleeding the system.
SUSPENSION SYSTEM
INSPECTION
Note: Do not adjust air suspension height
to any setting other than the specified
setting. Altering the height setting changes
the driveline angle and may result in
unwarrantable component damage, such
as transmission component damage.
Verify drive axle air suspension height and
height control valve performance at engine
oil change intervals.
Periodically check:
• Condition of spring leaves for evidence
of fatigue, bending or breakage.
• Condition of suspension mounting
brackets and bushings.
• Torque rod mounting fasteners for
tightness. •
For proper suspension alignment.
Maintain proper alignment at all times.
• U-bolts. After the chassis has been
operating under load for
1,000 mi
(1,600 km) or six months (whichever
comes first), the U-bolt nuts must be
re-torqued. Re-torque the U-bolt nuts
every
37,000 mi (60,000 km)
thereafter. Clean and lubricate the
U-bolt and nut threads and seats to
make sure a like new condition when
re-torqueing. See
Spring U-Bolt
Check (page 224).
FRAME AND TOW HOOK
INSPECTION
Your vehicle's chassis is manufactured
with frame rails of either HSLA steel or
heat-treated steel. Handle each in a
specific manner to make sure maximum
service life. Consult the service manual or
an authorized dealer before attempting
frame repair or modification.
It is important, particularly on vehicles that
use tow hooks frequently, to inspect the
front and rear tow hooks for damage or a
loose mounting.
REAR AXLE FLUID CHECK
Your rear axle may have an optional
synthetic lubricant that allows the use of
extended service intervals. A tag on the
filler plug identifies the use of the synthetic
lubricant.
Only use a lubricant that meets
manufacturer specifications. Only use a
lubricant that meets manufacturer
specifications. Use of a non-approved rear
axle lubricant may cause internal axle
component damage. See Capacities and
Specifications
(page 258).
