Keep lubricant sealed in and dirt and water out with the SKF Manual Transmission Seal / Transfer Case Output Shaft Seal 18658. It's a direct-fit replacement for the listed applications, including the 1974 Chevrolet Nova, 1981 Chevrolet Camaro, 1979-1981 Chevrolet Malibu, 1978-1979 Ford Bronco, and 1974-1981 Pontiac Firebird — see the Buyer's Guide tab for the full list. Cataloged in the REAR / REAR UPPER position, the seal body stays stationary in its bore while the flexible lip rides on the rotating output shaft.
Key features:
- Nitrile sealing surface: provides superior protection against dirt and water.
- Garter spring: uses cold-drawn steel wire to hold lip tension for superior fluid retention.
- Deep-drawn sheet steel body: forms a rigid, stress-resistant metal case.
- Tested design and materials: built to premium SKF standards for correct fit.
Dimensions: 1.875 in inside diameter, 2.750 in outside diameter, 0.313 in width, sized for a 1.875 in shaft. SKF has designed and developed shaft seals since inventing the first integrated shaft seal in 1928. This part is listed under both names — Manual Transmission Seal and Transfer Case Output Shaft Seal. If seepage or leaking lubricant traces to a worn output shaft seal, this replaces it. Country of origin: Mexico.
