ISSUE:





Since March 27, 1993, about 5,000 full floating rear axles have been built with a new cartridge type hub oil seal using Viton rubber. In addition, an oil slinger and shorter hub inner bearing are used. Service parts are not available for these hubs.

ACTION:
Do not attempt to repair these axles without consulting Ford personnel: 1-800-FORD-AXL (USA), (313) 826-5326 (For CANADA). A hardware exchange will be provided if necessary.

To identify this change, axle identification tags contain the numerical suffix "-3" immediately following the plant code.

CAUTION:
