TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING:
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. Make sure 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.
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 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).
