Roadside Emergencies 5. Repeat this tightness check procedure when servicing the spare tire pressure (every six months, per Scheduled Maintenance Guide), or at any time that the spare tire is disturbed through service of other components. 6.

WHEEL LUG NUT TORQUE SPECIFICATIONS Retighten the lug nuts to the specified torque within 100 miles (160 km) after any wheel disturbance (rotation, flat tire, wheel removal, etc.). Lug nut socket Wheel lug nut torque* size/Bolt size lb.ft. N•m 100 135 Lug nut socket size: 3⁄4 inch (19 mm) hex Bolt size: 1⁄2 x 20 * 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. 193 2008 Ranger (ran) Owners Guide (post-2002-fmt) USA (fus)
