Identification From Axle Tag:

Identification From Axle Tag

The axle tag is bolted to the rear differential cover and is held on with one of the cover bolts.

From the example above, you can see that the lower line shows the gear ratio, and axle diameter.

Ford 7.5-inch axle tag

So, from that example, we can see that the tag above is a 7.5-inch axle with 3.73 gears.

Ford 8.8-inch axle tag

The tag above is an 8.8-inch axle, and also has 3.73 gears, but there is a ‘L’ between the ‘3’ and the ’73’. This means that it is a Limited Slip axle.

How to read a Ford 8.8-inch axle tag

The tag above is from an 8.8-inch rear axle in a 2001 Ford Ranger 4×4 extended cab with 4.10 gears.
