Axle Details
The Ford 10.25" and Ford 10.5" axles, also known as Visteon and Sterling axles because they are manufactured by Visteon at the Sterling Axle Plant in Sterling Heights, MI, are exclusive to Ford and were first introduced in 1985. The two axles are almost identical with the only differences being that the 10.25" has a 1/4" smaller ring gear and a one-piece differential case with 2 pinion gears. Both models use large 35 spline axle shafts, however, some versions of the Ford 10.25" came with semi-floating axle shafts while all Ford 10.5" axles are full-floating. Differential parts including ring and pinion sets are interchangeable between the two axles.
