• Description:

  This is a genuine Ford inner pinion bearing for the rear axle of the 2019 through 2023 Ford Ranger. The bearing supports the inner end of the pinion gear shaft inside the differential carrier, riding against its matching race to hold the pinion in precise alignment with the ring gear while it carries the full driving torque of the rear axle. Pinion bearings live in a high-load, high-heat environment and wear gradually over the life of the vehicle. When the inner pinion bearing begins to fail, drivers usually hear a whine or howl from the rear of the truck that rises and falls with road speed, sometimes accompanied by a rumble felt through the floor or a growl that shifts between acceleration and coasting. Left unaddressed, a deteriorating bearing can damage the pinion and ring gears and contaminate the axle oil with metal debris. Ford service procedure treats the bearing and its race as a matched set, so both are replaced together and pinion preload is reset to specification during the rebuild. Proper installation requires pressing the bearing on squarely and verifying the gear contact pattern, so this is a job for someone equipped to set up a differential. As a factory Ford component it delivers the original load rating, tolerances, and durability of the bearing that shipped in the truck. Anyone tackling a Ranger rear-axle noise or a full differential overhaul will want this exact OEM bearing for a correct, lasting repair.
