2018 FORD F-650/750 tires

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)

1 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 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.

Multi-point Inspection
In order to keep your vehicle running right,
it is important to have the systems on your
vehicle checked regularly. This can help
identify potential issues and prevent major
problems. We recommend having the
following multi-point inspection performed
at every scheduled maintenance interval
to help make sure your vehicle keeps
running great. Multi-point Inspection
