ISSUE





All 2000-2004 F-150 (excluding F-150 equipped with 7-stud wheels and the 7700 payload group) and Expedition/Navigator built on or after November 27, 1999 will have revised wheel stud and wheel nut diameters. The wheel studs/nuts wilt have increased thread diameter from 12 mm to 14 mm. This change will include revised wheels, center wheel ornaments, hubs, brake rotors, wheel nuts, and lug wrench (two piece design and 13 cm (5") longer).

ACTION

The 14 mm wheel nut will require a 21 mm socket, instead of the 19 mm socket used on the 12 mm wheel nuts. The torque specification for the l4mm wheel nuts is 200 N.m (150 lb-ft). A TORQUE WRENCH MUST BE USED TO INSURE PROPER TORQUE IS ACHIEVED. The torque specification for the 12 mm wheel nut will remain at 133 N.m (100 lb-ft).

NOTE
THE 14 mm PARTS ARE NOT INTERCHANGEABLE WITH THE PREVIOUS 12 mm PARTS.
