When the vehicle is stopped while in 4H and
the vehicle's direction is reversed from the
previous direction, the automatic locking hubs
momentarily disengage and then re-engage.
The automatic locking hubs may click as they
automatically engage in the new direction.
*
[DR16640(B F )06/94]
To shift from 4H to 2H:
*
[DR16670(B F )03/93]
Move the transfer case shift lever straight
forward to the 2H position. This can be done at
any speed. To disengage the automatic locking
hubs, operate the vehicle in 2H in the opposite
direction for approximately 10 feet (3 meters).
*
[DR16701(B F )06/94]
For example:
*
[DR16730(B F )03/93]
If you were driving the vehicle forward in
4H, the automatic locking hubs will
disengage the next time the vehicle is driven
in reverse in 2H for approximately 10 feet (3
meters).
*
[DR16760(B F )03/93]
If you were driving the vehicle in reverse in
4H, the automatic locking hubs will
disengage the next time the vehicle is driven
forward in 2H for approximately 10 feet (3
meters).
*
[DR16790(B F )03/91]
Ð Operating in 2H with the hubs locked
increases fuel consumption, noise, vibration, and
wear. For prolonged 2H operation on dry
pavement, disengage the automatic locking hubs.
*
[DR16820(B F )06/94]
To shift between 4H and 4L:
*
[DR16851(B F )05/91]
Stop the vehicle and place the automatic
transmission into NEUTRAL or depress the
clutch on manual transmission vehicles. Push the
transfer case shift knob down (toward the
ground) and at the same time pull or push the
lever straight forward or rearward (depending
on the desired position, 4H or 4L) in order to
shift the transfer case. This shift should be in

[DR17270(B F )06/94]
Operating in 2H with the hubs in the LOCK
position increases fuel consumption, noise,
vibration, and wear. For prolonged 2H operation
on dry pavement, set the manual locking hubs
to the FREE position.
*
[DR17301(B F )06/94]
To shift between 4H and 4L:
*
[DR17330(B F )05/91]
Stop the vehicle and place the automatic
transmission into NEUTRAL or depress the
clutch on manual transmission vehicles. Push the
transfer case shift knob down (toward the
ground) and at the same time pull or push the
lever straight forward or rearward (depending
on the desired position 4H or 4L) in order to
shift the transfer case. This shift should be with
one continuous motion without pausing in the N
(neutral) position. Pausing in the neutral position
can result in gear clash and difficult shifting. If,
while shifting between 4H and 4L, the transfer
case gets stuck in the N (neutral) position or is
difficult to shift into either 4H or 4L, it may be
necessary to let the vehicle roll slightly and/or
turn off the engine (particularly on vehicles
equipped with automatic transmission).
*
[DR17390(B F )06/94]
To shift to N (neutral) from either 4H or 4L
*
[DR17420( F )05/91]
To shift into N (neutral), stop the vehicle and
engage the parking brake. Place the automatic
transmission into NEUTRAL or depress the
clutch on manual transmission vehicles. From
either the 4H or 4L position, push the transfer
case shift knob down (toward the ground) and
at the same time move the transfer case shift
lever to the N (neutral) position. The N (neutral)
position should only be used for vehicle towing
or transfer case mounted PTO use (transfer case
PTO opening available on F-350 only).

[DR17960(B F )06/94]
Ð The initial shift from two-wheel drive to 4x4
while the vehicle is moving can cause some
momentary clunk and ratcheting sounds. This is
the front drivetrain coming up to speed and the
automatic locking hubs engaging and is not a
cause for concern.
*
[DR17990(B F )12/91]
Ð Because of possible damage to powertrain
components, never shift from Two-Wheel Drive
to 4x4 with the rear wheels slipping.
*
[DR18020(B F )06/94]
To shift from 4x4 to Two-Wheel Drive:
*
[DR18050(B F )06/94]
Push the 4x4 button; the 4x4 lamp on the
instrument cluster will go out indicating the
vehicle is in Two-Wheel Drive. This can be done
at any speed. To disengage the automatic
locking hubs, operate the vehicle in Two-Wheel
Drive in the opposite direction for approximately
10 feet (3 meters) in a straight line.
*
[DR18080(B F )06/94]
For example:
*
[DR18110(B F )06/94]
If you were driving the vehicle forward in
4x4, the automatic locking hubs will
disengage the next time the vehicle is driven
in reverse in Two-Wheel Drive for
approximately 10 feet (3 meters) in a straight
line.
*
[DR18140(B F )06/94]
If you were driving the vehicle in reverse in
4x4, the automatic locking hubs will
disengage the next time the vehicle is driven
forward in Two-Wheel Drive for
approximately 10 feet (3 meters) in a straight
line.
*
[DR18170(B F )01/95]
Operating in two-wheel drive mode with the
hubs locked increases fuel consumption, noise,
vibration, and wear. For prolonged two-wheel
drive operation on dry pavement, disengagement
of the automatic locking hubs, which is not
required for two-wheel drive operation, stops all
