FORD F-350 2021 Owners Manual

10-lug nut torque sequence
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.

Stowing the Flat Tire or Spare Tire
1. Place the tire on end with the valve
stem facing toward the front of the
vehicle. Lay the tire on the ground, near
the rear of the vehicle, with the valve
stem side facing up. 2. Slide the wheel partially under the
vehicle and install the retainer through
the wheel center. If equipped, you may
have to remove the wheel center cap
prior to pushing the retainer through
the center of the wheel. To remove the
center cap, press it off with the lug
wrench tip from the inner side of the
wheel. Pull on the cable to align the
components at the end of the cable.
3. Turn the lug wrench clockwise until the
tire is raised to its stowed position
underneath the vehicle. The wrench
will become harder to turn and the
spare tire winch will ratchet or slip
when the tire is raised to maximum
tightness. You will hear a clicking sound
from the winch indicating that the tire
is properly stowed. Check that the tire
lies flat against the frame and is
properly tightened.
4. Carefully place all tools back in the tool
kit bag.
5. Reinstall the tool kit bag and tighten the wing nut.
6. Properly reinstall the jack into the bracket and tighten the wing nut.

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
