Lug Nut: Service and Repair
Wheel Fastener
WARNING: DUAL REAR WHEELS USE FLAT (INTEGRAL TWO-PIECE SWIVELING) 9/16-18 LUG NUTS; CONVENTIONAL NOT
PERMITTED.
Aluminum wheels on some vehicles are equipped with anti-theft lug nuts (one per wheel) that are installed during vehicle pre-delivery. The key is on the
right-hand side of the engine compartment. To allow vehicle service in the event the key has been misplaced, a Rotunda Master Key Set 164-R3104 or
equivalent is available at most Ford dealer service departments. The key has a circular keyway that is matched to the slot in the anti-theft lug nut.
CAUTION: Make sure the key is held square to the lug nut. If the key is on an angle, it can become damaged, or can damage the anti-theft lug nut. DO
NOT use a power impact wrench on the wheel hub bolt nut key.
To remove or install the anti-theft lug nut, insert the key into the slot of the lug nut, place the wheel hub bolt nut wrench on the key, and while applying
pressure on the key, remove or install the lug nut.
