Activating the Electronic Locking Differential (ELD)
Note:The ELD may have difficulty disengaging either by operator
command or automatically if the driveline is under torque. If driving
conditions allow, releasing the accelerator pedal or turning the steering
wheel in the opposite direction may assist in disengagement.
Note:The ELD is designed for off-road use only and is not intended for
use on dry pavement.
For vehicles equipped with an
electronic shift 4WD system:
Pull the 4WD control knob toward
you.
For 2WD vehicles and vehicles
equipped with a manual shift
4WD system:
Turn the control to ON.
Once the indicator light is displayed in the information display,
both rear wheel axle shafts will be locked together providing
added traction.
If the indicator does not come on, or the indicator turns off while
driving, one of the following has occurred:
•The vehicle speed is too high.
•The left and right rear wheel speed difference is too high during an
engagement attempt.
•The system has malfunctioned and will be accompanied by a message
in the information display. See your authorized Ford dealer for
assistance.

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 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 inWorkshop Manual.
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.

Note:The following steps apply to all vehicles:
18. Remove the jack and fully
tighten the lug nuts in the order
shown. SeeWheel Lug Nut Torque
Specificationsin this chapter for
the proper lug nut torque
specification.
8-lug nut torque sequence
10-lug nut torque sequence
19. Stow the flat tire. SeeStowing the flat or spare tireif the vehicle is
equipped with a spare tire carrier.
20. Stow the jack, jack handle and lug wrench. Make sure the jack is
securely fastened so it does not rattle when driving.
21. Unblock the wheels.
The following step applies to F-250 and F-350 Single Rear Wheel vehicles
only:
22.
When installing the wheel center
ornaments, ensure 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.

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.
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.
Inspect the wheel pilot hole and
mounting surface prior to
installation. Remove any visible
corrosion or loose particles.
