USING FOUR-WHEEL DRIVE
Note:
For important information regarding
the safe operation of this type of vehicle,
see General Information in the Wheels and
Tires chapter.
Note: Do not use 4H or 4L mode on dry,
hard surfaced roads. Doing so can produce
excessive noise, increase tire wear and may
damage drive components. 4X4 mode is
only intended for consistently slippery or
loose surfaces. Use of 4L mode on these
surfaces may produce some noise (such as
occasional clunks), but will not damage
drive components.
Note: If 4X4 low is selected while the
vehicle is moving above 3 mph (5 km/h),
the 4WD system will not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to or from 4L (4X4
Low) for proper operation.
Note: You can switch on and switch off the
electronic locking differential by pulling the
4WD control (4WD vehicles) or turning the
electronic locking differential control (2WD
vehicles). See
Electronic Locking
Differential (page 219).
Manual Shift On Stop (MSOS)
4WD system
(If Equipped)
Note: The vehicle should not be driven in
4X4 High or 4X4 Low modes with the hub
locks set to FREE as this condition may
damage driveline system components. The 4WD system is engaged or disengaged
by rotating the control for both front wheel
hub locks from the FREE or LOCK position,
then manually engaging or disengaging the
transfer case with the floor-mounted
shifter. For increased fuel economy in 2WD,
rotate both hub locks to the FREE position.
Electronic Shift-On-the-Fly
(ESOF) 4WD system
(If Equipped)
Note: If 4X4 Low is selected while the
vehicle is moving above
3 mph (5 km/h),
the 4WD system will not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to or from 4L (4X4
Low) for proper system operation.
Note: Auto-manual hub locks can be
manually overridden by rotating the hub lock
control from AUTO to LOCK. 210

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
during tight turns with low vehicle speed.
This is normal behavior and indicates the
axle is working.
ELECTRONIC LOCKING
DIFFERENTIAL (If Equipped)
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:
• The electronic locking differential will
not engage if your vehicle speed is
above
20 mph (32 km/h) in 4x2, 4x4
Auto, or 4x4 High modes.
• The electronic locking differential will
not engage if your vehicle speed is
above or
56 mph (90 km/h) in 4X4
Low. •
The electronic locking differential may
not engage if you press your
accelerator pedal during an
engagement attempt. A message may
display in the instrument display
guiding you to release the accelerator
pedal.
• In 4x2, 4x4 Auto, and 4x4 High modes,
the electronic locking differential will
automatically disengage at speeds
above
25 mph (41 km/h) and will
automatically reengage at speeds
below
20 mph (32 km/h).
• In 4L (4X4 low), the electronic locking
differential will automatically
disengage at speeds above
62 mph
(100 km/h) and will automatically
reengage at speeds below 56 mph
(90 km/h).
• The AdvanceTrac system has the
ability to take over control of the
electronic locking differential and
disable it during driving maneuvers
when necessary.
When you switch the system on, if you do
not meet the required conditions for
electronic locking differential activation,
the instrument cluster will display the
appropriate information guiding you
through the proper activation process.
Activating the Electronic Locking
Differential
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.

Super Duty (TFE) Canada/United States of America, enUSA, First Printing Rear Axle

For 4WD vehicles
Pull the 4WD control knob toward you.
For 2WD vehicles
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.

Turn the engine off and block the wheel
that is diagonally opposite of the flat
tire using the wheel chock. Note: Lock
the manual hub on the wheel if the
vehicle is a 4x4.
2. Remove the jack, jack handle, lug wrench and spare tire from the
stowage locations.
3. Use the tip of the lug wrench to remove
any wheel trim.
4. Loosen each wheel lug nut ½ turn counterclockwise, but do not remove
them until the wheel is raised off the
ground.
Note: For vehicles with dual rear wheels,
insert the lug wrench extension into the lug
wrench to reach the lug nuts.
F-250 and F-350 Single Rear Wheel
Vehicles 1. Insert the hooked end of the jack
handle into the jack and use the handle

1. Slide the notched end of the jack
handle over the release valve and use
the handle to slide the jack under the
vehicle. Make sure the valve is closed
by turning it clockwise.

Note:
Place the jack directly under the
I-beam. Front driver side (4x4): F-350 dual rear

area on the outboard side of the differential
housing. Front passenger side (4x4): F-350 dual
rear wheel
Note:
View shown from the rear of the
vehicle to clearly identify the jack point.
Note: Place the jack directly under the axle
and inboard of the radius arm so that the
jack clears the radius arm. Front: F-450 and F-550
