HOW TO FIGURE OUT WHAT MAKE DIFFERENTIAL YOU HAVE?

Ever wonder how to tell which brand of differential you have? If it’s still in the truck it easy and you can do it in less time than it takes to read this! All you have to do is look at the end of the axle shaft and see the marking. Its as simple as that!

This is the Rockwell/Meritor type. You can tell by looking at the two “half moon” markings on the center of the axle head.

This is the Alliance type, You can tell by looking at the “off center” half moon markings on the center of the axle head

This is the Eaton type. You can tell by the round indent on the center of the axle head

This is the Dana, Spicer or International type. You can tell by the diamond shape on the center of the axle head

This is the Detroit DART type. You can tell by the large dimple in the center of the axle head
