WHEEL LUG NUT TORQUE SPECIFICATIONS
Retighten the lug nuts to the specified torque at 500 miles (800 km)
after any wheel disturbance (tire rotation, changing a flat tire, wheel
removal, etc.).
Bolt size Wheel lug nut torque*
lb.ft. N•m
M12 x 1.5 100 135
* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
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. Ensure 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.
Note: Inspect the wheel pilot hole
prior to installation. If there is
visible corrosion in wheel pilot hole,
remove loose particles by wiping
with clean rag and apply grease.
Apply grease only to the wheel pilot
hole surface by smearing a “dime”
(1 square cm) sized glob of grease
around the wheel pilot surface (1)
with end of finger. DO NOT apply
grease to lugnut/stud holes or
wheel-to-brake surfaces.
