2019 FORD F-450 wheel torque

Using the Electronic Shift on the
Fly 4WD system (If Equipped)
2H (4X2)
For general on-road driving. Sends power
to the rear wheels only and should be used
for street and highway driving. Provides
optimal smoothness and fuel economy at
high speeds.
4H (4X4 HIGH)
Provides mechanically locked four-wheel
drive power to both the front and rear
wheels for use in off-road or winter
conditions such as deep snow, sand or
mud. This mode is not for use on dry
pavement.
4L (4X4 LOW)
Provides mechanically locked four-wheel
drive power to both the front and rear
wheels for use on low traction surfaces,
but does so with additional gearing for
increased torque multiplication. Intended
only for off-road applications such as deep
sand, steep grades, or pulling heavy
objects. 4L (4X4 low) will not engage while
your vehicle is moving above
3 mph
(5 km/h); this is normal and should be no
reason for concern. Refer to Shifting to or
from 4L (4X4 low) for proper operation. Shifting between system modes
Note:
Momentarily releasing the accelerator
pedal when a shift in progress message
displays improves engagement or
disengagement performance.
Note: Do not perform this operation if the
rear wheels are slipping or when applying
the accelerator pedal.
Note: Some noise may be heard as the
system shifts or engages; this is normal.
Note: 4X4 high mode is not intended for
use on dry pavement.
You can move the control from 2H or 4H
at a stop or while driving. The information
display may display a message indicating
a 4X4 shift is in progress. Once the shift is
complete the message center will then
display the system mode selected.
Shifting to or from 4L (4X4 low)
Note: Some noise may be heard as the
system shifts or engages; this is normal.
Note: 4x4 low mode is not intended for use
on dry pavement.
1. Bring the vehicle to a speed of
3 mph
(5 km/h) or less.
2. Place the transmission in N (Neutral).
3. Move the 4WD control to the desired position.
The information display will display a
message indicating a 4X4 shift is in
progress. The information display will then
display the system mode selected. If any
of the above shift conditions are not met,
the shift will not occur and the information
display will display information guiding the
driver through the proper shifting
procedures.

•
Do not operate the vehicle if the power
steering pump fluid level is 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 you switch the engine off, you can
steer the vehicle manually, but it takes
more effort.
If you have any steering components
serviced or replaced, install new fasteners.
Many fasteners have coatings with thread
adhesive, or have prevailing torque
features you cannot reuse. Do not reuse a
bolt or nut. Torque fasteners to
specifications.
Steering Tips
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.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull. Electronic Variable Overlay Power
Steering (If Equipped) WARNING:
The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the ignition off. After at least 10
seconds, switch the ignition on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked as
soon as possible. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Have your vehicle checked as
soon as possible. Failure to do so may
result in loss of steering control.
The electronic variable overlay power
steering system adds supplemental
steering assist to the hydraulic gear when
needed, dependent on vehicle conditions
such as vehicle speed, steering wheel
angle, and steering wheel torque. The
hydraulic steering system provides the
majority of steering assistance. The
electronic variable overlay torque enables
features such as pro trailer backup
assistance and lane departure warning.
If your vehicle loses electrical power while
you are driving, your vehicle loses electric
power steering assistance. The steering
system still operates, and you can steer
your vehicle with hydraulic assist. Steering
your vehicle with only hydraulic assist
requires more effort.

Jack at the specified locations to
avoid damage to the vehicle.
Jacking the Vehicle 1. Insert the hooked end of the jack
handle into the jack and turn the
handle clockwise until the wheel is
completely off the ground and high
enough to install the spare tire.
2. Remove the lug nuts with the lug wrench.
3. Replace the flat tire with the spare, making sure the valve stem of the
spare is facing outward when replacing
a front wheel. For the rear wheel
position on vehicles with single rear
wheel fitments, install the spare with
the valve stem facing outward. For
vehicles with dual rear wheels, the
valve stem of the spare must face
outward when replacing an inner
wheel, but must face inward when
replacing an outboard wheel.
4. Reinstall the lug nuts until the wheel is
snug against the hub. Do not fully
tighten the lug nuts until the vehicle
has been lowered.
5. Lower the wheel by turning the jack handle counterclockwise. 6. Remove the jack and fully tighten the
lug nuts in the order shown. See

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)

* 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. 417
