Engineers at Ford Motor Co. have developed two new, lighter axles to help meet fuel economy standards. The new axles will replace heavier-duty axles which were required for deleted 6.6-L and 7.5-L engines. The new units, designated by Ford as 7.5 in. and 8.5 in. axles, are cast center axles and are available in 1979 Ford and Mercury full-sized cars. Fuel efficiency and improved handling were primary goals in the new designs. Included in the initial design assumptions were benefits in the areas of improved reliability, manufacturing flexibility, reduction in complexity, common axle ratios, and low ratio capacity. Axle designations were derived from respective nominal ring gear diameters. Both axles were designed to be interchangeable in cars where torque capacity permits.
