Ford Design Axles

FIG. 3 Rear Driving Axle Model Identification Tag:

The plant code on the axle identification tag is to be used as the official service identifier (Fig. 3).

FIG. 4 Internal Change Identification Tag:

The Plant Code for a particular axle assembly will not be duplicated. In addition, the Plant Code will not change as long as that particular axle assembly never undergoes an external design change. If, however, an internal design change takes place during the production life of the axle and that internal change affects service parts interchangeability, a dash and numerical suffix will be added to the Plant Code (Fig. 4).

Note: Plant Codes in Figs. 3 and 4 are identical except Fig. 3 shows a numeric. This means that AS AN ASSEMBLY both axles are interchangeable; however, internally they are different. Therefore, each would require different internal service parts at service time.
