The Ford 7.5-Inch Axle
The Ford 7.5-Inch axle came in a few different vehicles including the:
For the purpose of this article, we're only going to discuss the Ford Ranger and Bronco II.
All Ford Bronco II's (1984-1990) came with a 7.5-Inch rear axle.
All Ford Rangers came with a 7.5-Inch axle from 1983-1989.
From 1990-2011, all 4.0L Ford Rangers came equipped with a 8.8-Inch axle.
1990-2011 Ford Rangers without a 4.0L V6 came with a 7.5-Inch rear Axle, but the 1998-2011 super cabs 4x4 models came with a 8.8-Inch axle regardless of engine size.
Axle Width Differences:
People have asked about the widths of axle shafts to swap shafts from one axle to another.
The early 1983-1992 Ranger axles are 1-inch shorter than the 1993-up pieces (Both sides). This means that the an entire Ranger axle assembly from 1993-up is 2-inches wider than 1983-1992.
The right side Bronco II axle shaft is 1-5/8" wider than the 1983-1992 Ranger shaft. All of this additional width is on the passenger side. The drivers side shaft is the same length in either axle assembly.
On ALL Ranger/Bronco II's the drivers side axle shaft is longer than the passenger side.
There is no difference between 7.5 & 8.8 axle shaft lengths provided you stay in the same year window.
Mustang Note: If you go to a salvage yard, you may find that the left side shafts have been removed from 1983-1992 Rangers and Bronco II's. These axle shafts are the same length as the axle shafts in the "Fox" (1979-1993) Mustangs EXCEPT that Ranger/Bronco II shafts are five-lug and Mustangs are four lug. Ranger/Bronco II shafts are frequently "pillaged" for use in converting a Mustang to five-lug wheels.
Identifying Your Axle:
can identify which axle you have by the tag attached to the inspection
Looking at that tag, you can see the gear ratio stamped on the lower left, and the axle size (ring gear diameter) stamped in the bottom middle.
So looking at the axle tag above, you can see it's a 3.73 gear ratio in a 7.5 inch axle.
The Ford 7.5-Inch axle can also be identified by the sicker on the drivers door. Check out our Ford 7.5 & 8.8 Inch Axle Code page for a break down of codes.
