Drive Axle Identification

Fig. A metal axle identification tag is attached to the differential by a housing cover bolt and contains the following information: plant code (1); interchangeability (2); axle ratio (3); ring gear diameter (4); build year (5); build month (6); and build day (7). The axle identification tag identifies a particular axle design and a specific ratio. 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 parts interchangeability, a dash and numerical suffix is added to the plant code. This means that as an assembly both axles are interchangeable; however, internally they are different. Therefore, each requires different internal parts at the time of repair
