Shifting From 4H (4Wd High) To 2H (2Wd High); Shifting From 4H (4Wd High) To 4L (4Wd Low); Shifting From 4L (4Wd Low) To 4H (4Wd High) Or 2H (2Wd High) - Ford F-550 Owner's Manual

Shifting from 4H (4WD High) to 2H (2WD High)

Move the transfer case lever to 2H
(2WD High) at a stop or a vehicle
speed below 3 mph (5 km/h).
With the vehicle at complete stop,
disengage the locking hubs
(optional) by rotating the hub lock
control from LOCK to FREE.
• For proper operation, make
sure that both indicator arrows on the hub are aligned, and
that both hubs are set to FREE

Shifting from 4H (4WD High) to 4L (4WD Low)

1. Bring the vehicle to a speed below 3 mph (5 km/h).
2. Place the gearshift lever in N (Neutral). If the vehicle is equipped with
a manual transmission, also depress the clutch pedal.
3. Move the transfer case shift lever
through N (Neutral) directly to 4L
(4WD Low). If the shift lever does
not, or only partially moves to the
4L (4WD Low) position, perform a
shift with the transmission in N
(Neutral) (or clutch pedal
depressed) and the vehicle rolling at
a speed below 3 mph (5 km/h). This
will ensure the transfer case is fully engaged into 4L (4WD Low).

Shifting from 4L (4WD Low) to 4H (4WD High) or 2H (2WD High)

1. Bring the vehicle to a speed below 3 mph (5 km/h).
2. Place the gearshift lever in N (Neutral).
3. Move the transfer case shift lever
through N (Neutral) directly to 4H
(4WD High) or 2H (2WD High).
4. If the transfer case will not
engage into 4H (4WD High) or 2H
(2WD High), allow the vehicle to
move at a speed above 1 mph
(1.6 km/h), then repeat steps 2 and 3.
5. If shifting to 2H (2WD High) with the vehicle at a complete stop,
disengage the locking hubs (optional) by rotating the hub lock control
from LOCK to FREE.
