Driving your vehicle with the warning
lamp on is dangerous. A significant
decrease in braking performance
may occur. It will take you longer to stop
your vehicle. Have your vehicle checked by
your authorized dealer immediately. Driving
extended distances with the parking brake

risk of personal injury. Check Fuel Cap (If Equipped)
Illuminates when the fuel cap
may not be properly installed.

LIMITED SLIP DIFFERENTIAL
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 in
tight turns with low vehicle speed. This is
normal behavior and indicates the axle is
working.
ELECTRONIC LOCKING
DIFFERENTIAL
Note:
The electronic locking differential is
for off-road use only and is not for use on
dry pavement. Using the electronic locking
differential on dry pavement will result in
increased tire wear, noise and vibration.
The electronic locking differential is a
device housed in the rear axle that allows
both rear wheels to turn at the same
speed. The electronic locking differential
can provide additional traction should your
vehicle become stuck. You can activate
the differential electronically and shift it
on the fly within the differential operating
speed range. The differential is for use in
mud, rocks, sand, or any off-road condition
where you need maximum traction. It is
not for use on dry pavement.
The following conditions will affect the
electronic locking differential: •
On 2WD vehicles and 4WD vehicles in
2H (4X2) or 4H (4X4 High), the ELD
will not engage if the vehicle speed is
above 20 mph (32 km/h).
• On 2WD vehicles and 4WD vehicles in
2H (4X2) or 4H (4X4 High), the ELD
will automatically disengage at speeds
above 25 mph (40 km/h) and will
automatically reengage at speeds
below 20 mph (32 km/h).
• On 4WD vehicles in 4L (4X4 Low), the
ELD can be engaged at any speed and
will not automatically disengage.
Activating the Electronic Locking
Differential (If Equipped)
Note: Do not use electronic locking
differential on dry, hard surfaced roads.
Doing so will produce excessive noise,
vibration and increase tire wear.
Note: If the electronic locking differential
has difficulty disengaging, release the
accelerator pedal and turn the steering
wheel in the opposite direction while rolling.
For vehicles equipped with an
electronic shift 4WD system Pull the 4WD control knob toward you.

Super Duty (TFA) Rear AxleE163190

For 2WD vehicles and vehicles
equipped with a manual shift 4WD
system
Turn the control to ON.
Once the indicator light
illuminates 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 is
accompanied by CHECK LOCKING
DIFFERENTIAL in the information
display. See your authorized Ford
dealer for assistance.

Note:
Make sure the jack fits onto the flat
area on the outboard side of the differential. Front passenger side (4x4)
Note:
View shown from the rear of the
vehicle to clearly identify the jack point.
Place the jack directly under the axle. Rear
Note:
Jack at the specified locations to
avoid damage to the vehicle. Jacking the vehicle 1. Turn the jack 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 tire,
making sure the valve stem is facing
outward for all front wheels and single
rear wheel vehicles. If you are replacing
an inboard rear tire on dual rear wheel
vehicles, the valve stem must be facing
outward. 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.
4. Lower the wheel by turning the jack handle counterclockwise.
5. Remove the jack and fully tighten the lug nuts in the order shown. See
Technical Specifications (page 290).
6. Stow the flat tire. See Stowing the flat or spare tire if the vehicle is equipped
with a spare tire carrier.
7. Stow the jack, jack handle and lug wrench. Make sure the jack is securely
fastened so it does not rattle when
driving.
8. Unblock the wheels.
