2015 FORD F450 Owners Manual

8-lug nut torque sequence.
10-lug nut torque sequence.
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 lug
nuts. The retention towers are designed to
be installed over the studs or nuts and
retain to the flange on the lug nut. If the ornament retention towers are
aligned between the studs or lug nuts, the
ornament is 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 will fall
off or become loose with minimal force or
impact.

F-550 Vehicles
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.
2. Position the jack according to the following guides:

Front (4x2): F-350 dual rear wheel.
Note:
Place the jack directly under the
I-beam. Front driver side (4x4): F-350 dual rear
wheel.
Note:
Make sure the jack fits onto the flat
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.
Rear: F-350 dual rear wheel.
Rear: F-450 and F-550.

Jacking the Vehicle
1. Insert the jack handle into the pump
linkage.
2. Use an up-and-down motion with the jack handle to raise the wheel
completely off the ground.
Note: Hydraulic jacks are equipped with a
pressure release valve that prevents lifting
loads which exceed the jack's rated
capacity.
3. Remove the lug nuts with the lug wrench.
4. Replace the flat tire with the spare tire,
making sure the valve stem is facing
outward on all front an inboard rear
wheels. If you are replacing the
outboard wheel, the valve stem must
be facing inward. 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.
5. Lower the wheel by slowly turning the release valve counterclockwise.
Opening the release valve slowly will
provide a more controlled rate of
descent.
6. Remove the jack and fully tighten the lug nuts in the order shown. See
Technical Specifications (page 299).
7. Stow the flat tire. See Stowing the flat or spare tire if the vehicle is equipped
with a spare tire carrier. 8. Stow the jack, jack handle and lug
wrench. Make sure the jack is securely
fastened so it does not rattle when
driving.
9. Unblock the wheels. 8-lug nut torque sequence.

1. Align the ornament with the lug nuts.
A is the clip and B is the flange. 2. Hold the ornament so that all of the
retention clips are sitting on the flange
of the lug nuts. 3. Use your hand or rubber mallet to tap
the ornament in a star pattern. There
should be an even gap between the
ornament and the wheel.
4. Be sure to install all the clips on the nuts over the flanges so that there is
an even gap all around and the
retention clips are fully seated. Stowing the Flat or Spare Tire
Note:
Failure to follow spare tire stowage
instructions may result in failure of cable or
loss of spare tire.
Note: If you are stowing a tire that requires
reattaching it to the vehicle with a tether,
perform these steps first, then proceed with
the following steps.
1. Place the tire on end with the valve stem facing toward the front of the
vehicle.
2. Place the tether into the bolt holes in the wheel and attach the lug nut using
the lug wrench.

3. Lay the tire on the ground with the
valve stem facing up.
4. Slide the wheel partially under the vehicle and install the retainer through
the wheel center. Pull on the cable to
align the components at the end of the
cable.
5. Turn the jack handle clockwise until the tire is raised to its stowed position
underneath the vehicle. The effort to
turn the jack handle increases
significantly and the spare tire carrier
ratchets or slips when the tire is raised to the maximum tightness. Tighten to
the best of your ability, to the point
where the ratchet/slip occurs, if
possible. The spare tire carrier will not
allow you to overtighten. If the spare
tire carrier ratchets or slips with little
effort, take the vehicle to your
authorized dealer for assistance at your
earliest convenience.
6. Check that the tire lies flat against the frame and is properly tightened. Try to
push or pull, then turn the tire to be
sure it will not move. Loosen and
retighten, if necessary. Failure to
properly stow the spare tire may result
in failure of the winch cable and loss
of the tire.
7. Repeat this tightness check procedure
when servicing the spare tire pressure
(every six months, per scheduled
maintenance information), or at any
time that the spare tire is disturbed
through service of other components.
8. If removed, install the spare tire lock into the bumper drive tube with the
spare tire lock key and jack handle.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING
When a wheel is installed, 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 that any fasteners
that attach the rotor to the hub are secured 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 the vehicle is in motion, resulting in loss of control. lb.ft (Nm)
Bolt size
165 lb.ft (224 Nm)
M14 x 1.5
* Torque specifications are for nut and bolt threads free of dirt and rust. Use only Ford
recommended replacement fasteners.
On vehicles equipped with single rear wheels, retighten the lug nuts to the specified torque
at 100 miles (160 kilometers) after any wheel disturbance (such as tire rotation, changing
a flat tire, wheel removal).
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts to the specified
torque at 100 miles (160 kilometers), and again at 500 miles (800 kilometers) of new
vehicle operation and after any wheel disturbance (such as tire rotation, changing a flat
tire, wheel removal).
It is important to follow the proper wheel mounting and lug nut torque procedures.
On all two-piece flat wheel nuts, apply one drop of motor oil between the flat washer
and the nut. Do not apply motor oil to the wheel nut threads or the wheel stud threads. 299
