The Eaton HN129 is a Nut-Pinion for differentials. A pinion nut clamps the pinion shaft assembly in the differential carrier and holds its position under drive load. Its locking function keeps preload and alignment from backing off, so a loose or worn pinion nut shows up as play in the pinion and a change in gear noise. A genuine Eaton part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
