What does F250 axle code 39 mean?

The sticker in the door of my truck has the number 39 printed under “axle,” but I don’t know what that means. Can you tell me what F250 axle code 39 means?

Axle codes tell you what type of differential and ratio you have. Your

’s axle code 39 means that you have a 3.55 non-limited-slip. This is a type of open single-wheel rear axle. As you already know, you can find the information about your axle on the sticker located on the latch face of the left front door. In addition to axle info, it also tells you tons of other information about your vehicle, from the wheelbase to the transmission. If you have any questions about your axle or think it might need repair, head to a local mechanic: it’s not a job to be tackled at home! In the meantime, why not update your auto insurance with
