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.

*Torque specifications are for nut and bolt threads free of dirt and rust. Use only Ford
recommended replacement fasteners.
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).
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.
