Roadside Emergencies WHEEL LUG NUT TORQUE SPECIFICATIONS On vehicles equipped with single rear wheels, 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.). On vehicles equipped with dual rear wheels, retighten the wheel lug nuts to the specified torque at 100 miles (160 km), and again at 500 miles (800 km) of new vehicle operation and after any wheel disturbance (tire rotation, changing a flat tire, wheel removal, etc.). Wheel lug nut torque* lb.ft. N•m M14 x 1.5 150 200 * Torque specifications are for nut and bolt threads free of dirt and rust. Use only Ford recommended replacement fasteners. 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. Bolt size 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 front disc brake hub and rotor that contacts 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. 321 2008 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
