* 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.

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. 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.
