How do you decode a Ford rear end tag?

Decoding a Ford Rear End Tag
Decoding a Ford rear end tag involves identifying the axle size, gear ratio, and other relevant information. The tag attached to the inspection cover provides crucial details for identification.
To decode a Ford rear end tag, you can follow these steps:
1. Identify the Axle Tag: The tag attached to the inspection cover contains important information such as the gear ratio and axle size. For example, the gear ratio is typically stamped on the lower left, and the axle size (ring gear diameter) is stamped in the bottom middle.
2. Use the Axle Code (Door Sticker): Rear axle codes can also be found on the Safety Standard Certification label attached to the left driver’s side door lock post. The code appears as a number or letter/number combination in the ‘Axle’ column of the label. This code can be used to determine the axle type and capacity.
3. Consult Differential Experts: If in doubt, it’s advisable to consult differential experts who can provide professional technical support and help identify the differential based on the tag number or axle tube stamp.
4. Decode the Tag Information: The tag on the rear end provides details such as the axle plant that built it, the differential type (open or limited slip), the ring gear diameter, and the build date. By posting the data from the tag, experts can assist in decoding it to ensure the rear end is the correct one for the vehicle.
By following these steps and utilizing the information provided on the axle tag and door sticker, you can successfully decode a Ford rear end tag to identify the specific characteristics of the axle.
