Ford 8.8 Axle Tag Decoder Diagram - Ratio, Plant Code, Build Date (Bronco)

This document is a Ford service-manual style illustration explaining how to read a Ford rear axle identification tag (data/spec plate). The drawing shows a metal tag with a mounting hole and stamped markings, with callouts identifying what each stamped field means. The example tag reads 'S052B' (identified as the plant code), '3.08' (identified as the conventional axle ratio, noted as 3.08 non-locker, while a '3L08' marking would indicate a Traction-Lok limited-slip differential), '8.8' (the ring gear diameter in inches), and '7K 20' (the build date, decoded as year, month, and day). The illustration reference number is AE0206-A. A reader can learn how to decode their own Ford axle tag: where to find the plant code, how to determine whether the axle is an open (conventional) differential or a Traction-Lok limited slip based on whether the ratio marking includes an 'L', how to read the ring gear size (8.8 inches in this example), and how to interpret the build date stamping. The document itself does not state a specific vehicle model or model year applicability.
