* Front: Dana 44 HD (High Duty) was very common. A less common possibility is a Dana 60.
* Rear: Ford 9.75" was a popular choice. A Dana 60 was also a possibility, particularly with heavier-duty packages.
To know for sure what axles are in *your* specific 1976 F-250 4x4, you need to:
* Check the data plate: Located usually on the driver's side door jamb or the glove box, this plate lists the truck's specifications, potentially including axle information.
* Look at the axles themselves: The axle housing typically has a casting number that can be looked up in a parts catalog or online database to identify the axle type. This requires some mechanical knowledge and access to the axle.
* Check the build sheet (if available): Original build sheets provide detailed information about the truck's components.
Without looking at your specific truck, it's impossible to say definitively which axles are installed.
