Check specification listing to ensure that you have identified the correct rear end. The Ford 9.75" was introduced in 1997 and was used in Ford's uprated-capacity 1/2-tons. Its primary use was in the new-generation F-150s with the higher GVW package or 5.4L V-8, but it can also be found under the '98-'02 Ford Expeditions and Lincoln Navigators. It's also been used in the limited-production 4x2 Ford SVT Lightning hot-rod pickups. There is an IRS version that replaced the beam axles in the '03-and-up SUVs.

The 9.75 has had a few modifications since its introduction, including larger axle bearings and shafts in 1999 (from a 1.620-inch inner diameter to 1.705 inches), a larger outer pinion bearing (increased from 1.31 x 2.68 inches to 1.31 x 3.00 inches), and the pinion was altered for a longer crush sleeve.
