Wheel Lug Nut Torque Specifications
WARNING
When you install a wheel, always remove any corrosion, dirt or foreign m\
aterials 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 co\
me off while your vehicle is in motion, resulting in loss of vehicle
control, personal injury or death. lb.ft (Nm)
