Identifying Your Ford Rear End
To identify your Ford rear end, there are several methods you can use. Here are a few options:
1. Differential Tags and Stampings: The most accurate way to identify your Ford rear end is by checking the bottom line of the tag number or the axle tube stamp. Differential tags can be used to identify both Dana and Ford differentials.
2. Door Sticker: You can also find information about your Ford rear end on the door sticker of your vehicle. Open the driver’s door and look at the door jamb. You’ll see a sticker that contains an axle code. You can refer to a chart to identify the specific rear end based on the axle code.
3. Bolts and Gasket Shape: Another method is to count the bolts on the rear-end housing and visually identify the rear-end gasket shape. Different Ford rear ends have different bolt counts and gasket shapes. By comparing these details with a chart, you can determine the type of rear end you have.
4. Model Numbers: Some Ford rear ends have model numbers attached to the rear end housing. By locating and identifying these model numbers, you can determine the specific type of rear end you have.
It’s important to note that these methods may vary depending on the specific model and year of your Ford vehicle. If you’re unsure or need further assistance, it’s recommended to consult with a differential expert or contact Ford’s Customer Relationship Center for more information.
