Ford 7.5-Inch and 8.8-Inch Axle Visual Identification:

Both axles use (10) bolts to hold on the cover, but there is an obvious difference in their shape.

Ford 7.5-Inch rear axle above – Ford 8.8-Inch rear axle below.

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.

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

The tag above is a 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.

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

Federal Compliance Sticker:

Another way to identify the axle in a Ford Ranger is from the Federal Compliance Sticker in the door jamb.

If you look at the ‘AXLE’ section on the label above, you’ll see that this Ranger has a ‘F7’ axle code. Using the chart below, we know that this axle is a 7.5-Inch axle with a 4.10 limited slip.
