F-350 Dual Rear Wheel Vehicles
Remove the lug nuts with the lug wrench,
replace the flat tire with the spare, making
sure the valve stem of the spare is facing
outward when replacing a front wheel. For
the rear wheel position on vehicles with
single rear wheel fitments, install the spare
with the valve stem facing outward. For
vehicles with dual rear wheels, the valve
stem of the spare must face outward when
replacing an inner wheel, but must face
inward when replacing an outboard wheel.
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.
Lower the vehicle completely by turning
the jack handle counterclockwise until the
vehicle is completely lowered. Note:
For F-350 Dual Rear Wheel, F-450
and F-550 Vehicles, insert the notched end
of the jack handle to the release valve, open
the release valve slightly by turning the
handle counterclockwise. Stop turning the
release valve when vehicle start to lower.
Make sure to close the valve when you
completely lower your vehicle.

Note:
When installing the wheel center
ornaments, make sure that the ornament
retention towers on the back side of the
ornament are aligned with the studs or nuts
and retain to the flange on the lug nuts. Note:
For dual rear wheels, align the
ornament with the lug nuts. (A) is the clip
in the ornament and (B) is the flange of the
lug nut. Make sure that each of the retention
clips are sitting on a lug nut flange. Note:
If the ornament retention clips are
aligned between the studs or lug nuts, the
ornament will be improperly installed. This
improper installation may appear and sound
correct, but will not keep the ornament on
the vehicle. Ornaments improperly installed
in this manner may become loose or fall off
during driving. Use your hand or a rubber mallet to tap the
ornament until the retention clips snap
over the lug nut flanges. Tap in a star
pattern until the ornament seats fully onto
the wheel. There should be an even gap
between the ornament and the wheel
when it is properly installed.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING: When you install a wheel, 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 to secure any fasteners
that attach the rotor to the hub 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
your vehicle is in motion, resulting in loss of vehicle control, personal injury or death. lb.ft (Nm)

recommended replacement fasteners.
On vehicles equipped with single rear wheels, retighten the lug nuts to the specified torque
at 100 mi (160 km) after any wheel disturbance, such as tire rotation, changing a flat tire,
or wheel removal.
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts to the specified
torque at
100 mi (160 km), and again at 500 mi (800 km) of new vehicle operation and
after any wheel disturbance, such as tire rotation, changing a flat tire, or wheel removal.
It is important to follow the proper wheel mounting and lug nut torque procedures. Wheel pilot bore
