• Description:

  This is a genuine Ford rear axle differential pinion bearing race, also known as the pinion bearing cup, for the 2019 through 2023 Ford Ranger. The race is the hardened outer ring that the pinion bearing rollers ride against inside the rear axle carrier. It is press-fit into the differential housing and provides the precise, wear-resistant surface that keeps the pinion gear correctly positioned and supported as it transmits torque from the driveshaft to the ring gear. A worn or pitted race lets the pinion shift under load, which shows up as a whine or howl from the rear axle that changes with vehicle speed, a growling noise on acceleration or deceleration, and in advanced cases metal contamination in the gear oil. Because the race and its matching bearing wear as a matched pair, Ford service practice calls for replacing them together and resetting pinion preload during installation. Correct seating depth is critical to proper gear mesh, so this component should be installed by someone equipped to press it in squarely and verify pattern and preload. As a factory Ford part it matches the original metallurgy, dimensions, and finish of the race that left the assembly line, ensuring proper fitment in the Ranger rear axle and long service life. Buyers searching for this part are typically chasing a rear-end noise or performing a differential rebuild and want the exact OEM cup rather than a guesswork replacement. Confirm your axle configuration against the part before ordering.
