1992-1997 Ford F350 Dana 60 Front Axle Identification IDN-138

1992-1997 Dana 60 Front Axles in Ford F-350 4x4 Trucks will typically have the Ford Build Code on a mylar decal affixed to the right axle tube. Also, the Dana Bill of Material Number (BOM) and Ford Build Code are stamped on a Build Tag (red arrow) attached to the differential by two of the differential cover bolts (yellow arrows) when the vehicle was shipped from the factory but, unfortunately, these tags are often missing on trucks that had prior differential service. The Dana BOM number is also stamped on the front side of the right axle tube. The BOM number is a 6 digit number beginning with a 6 plus a dash number (ex: 610604-2). They can be used to determine not only the axle model, but also what components the axle was originally built with. We often ask for this number to insure we provide you with the exact parts you need for your truck.

Each different BOM number signifies an engineering part change which may be minor or major and may involve one or more parts. The dash number indicates the axle ratio and, for some years, the front wheel hub style (for single or dual rear wheel models).
