Support axial and radial loads with the Schaeffler Wheel Bearing and Race Set / Differential Bearing K387AS-382A, a tapered roller bearing (TRB) set built around a precision cup and cone design. It fits many vehicles, among them the 1992-2009 Ford F-250, 1999-2011 Chevrolet Silverado 2500 and 2004-2019 Ford E-350 Super Duty. See the Buyer's Guide tab for the full list.
Schaeffler is a trusted OEM supplier, and it engineers its tapered roller bearing sets for performance and precision. The cone's rollers run against a matching cup (race), and the design is intended to spread forces evenly across the bearing. This set is listed under both the wheel bearing and race set and differential bearing names. It is cataloged for the rear, front inner, rear outer and rear inner positions, depending on the application.
- Axial & radial support: Engineered to handle both axial and radial forces with precision and reliability.
- Even load distribution: The cup and cone design helps distribute forces evenly to enhance performance.
- OEM-grade quality: Produced to the stringent standards set by original equipment manufacturers.
- Durability: Made from high-strength materials designed to withstand extensive use in demanding conditions.
Signs that a tapered bearing may need replacing include grinding, growling or humming noise that changes with speed, roughness, or excess play. These symptoms can have other causes, so diagnose the problem before replacing parts. Follow the vehicle service information for installation, adjustment and lubrication.
