Differential Crush Sleeve, Spacer Pinion Bearing
- Description:
This genuine Ford part is the differential pinion bearing spacer, cataloged by Ford as Spacer - Pinion Bearing, used in the rear axle carrier of 2019-2025 Ford Ranger models with the 2.3L EcoBoost and 2021-2024 Ford Bronco models with the 2.3L, 2.7L or 3.0L engine. The spacer sits on the pinion shaft between the pinion bearings and sets the correct bearing preload and pinion position as the pinion nut is torqued, which establishes the running clearance and mesh pattern between the pinion and ring gear. Correct pinion bearing preload is essential to quiet, durable axle operation, so this component is installed and set during ring-and-pinion setup or a differential rebuild. Buyers reaching for this part are typically rebuilding or resetting a rear differential, replacing worn or noisy pinion bearings, or chasing an axle that has developed a gear whine or howl on acceleration or coast. It is a setup component that should be replaced whenever the pinion is disturbed, and pinion preload must be re-established to the published Ford specification during assembly. Install with clean, properly lubricated bearings and verify preload before final torque.
- Applications: W/LIMITED SLIP. W/O LOCKING DIFFERENTIAL.
