This rear output shaft seal is a replacement for many vehicles, among them the 1973-1974 Chevrolet K10 Pickup, 1973-1974 Chevrolet K10 Suburban and 1973-1974 Chevrolet K20 Pickup.

SKF has led in seal design since it invented the first integrated shaft seal in 1928, and it has kept developing new designs and bonding techniques since then. Its seals follow specific designs and use premium materials chosen for the application and its operating environment. Their job is to keep lubricants in and contaminants out.
- Tested for fit: Manufactured with a high-quality, tested design and materials for correct fit.
- Garter spring: Made from cold drawn steel wire to help retain fluid.
- Metal case: Deep drawn sheet steel forms a rigid, stress-resistant body.
- Contaminant protection: Designed to guard against dirt and water.
The seal body stays stationary while its sealing lip rides against the rotating output. Signs this seal may need replacing include lubricant seeping or dripping at the rear output of the transfer case, or a dropping fluid level. Other components can also leak, so confirm the source before replacing. If a worn rear output shaft seal is the cause, this part replaces it.
