How do I know what Ford differential I have?

Introduction
If you’re looking to determine what Ford differential you have, there are a few methods you can use. Let’s explore some ways to identify your Ford differential.
Using Tag Numbers or Axle Tube Stamps
One of the most accurate ways to identify your Ford differential is by checking the tag number or axle tube stamp. These markings can provide valuable information about the differential. You can refer to the bottom line of the tag number or the axle tube stamp for identification.
Checking the Number of Bolts and Inspection Cover
Another method to identify your Ford differential is by comparing the number of bolts and the shape of the inspection cover gasket. Different Ford models have varying numbers of bolts, and certain Dana units may have the same bolt count. By comparing the bolt count and inspection cover gasket shape to a differential identification listing, you can narrow down the possibilities.
Consulting Online Resources
There are online resources available that can help you identify your Ford differential. Websites like DIYFord.com and Ford Truck Enthusiasts have information and forums where you can find guidance from experts and fellow enthusiasts. These resources can provide specific details and answer any questions you may have.
Seeking Professional Assistance
If you’re still having trouble identifying your Ford differential, it may be helpful to consult a professional. They have the expertise and knowledge to accurately identify different types of differentials. You can reach out to a local mechanic or a differential specialist for assistance.
Remember, accurate identification of your Ford differential is crucial when it comes to repairs, upgrades, or maintenance. If you’re unsure about any aspect of the identification process, it’s always best to seek professional guidance.
