Keep gear lubricant where it belongs with the SKF differential pinion seal, part number 18888. It is also listed as a drive axle shaft seal. It is a direct-fit replacement for the listed applications, including the 1955-1970 Ford F-250, 1961-1972 Chevrolet C10 Pickup, 1966-1972 Dodge Charger and 1967-1972 GMC C15/C1500 Pickup. It is cataloged for front and rear positions. See the Buyer's Guide tab for the full list of applications and engine details.
The seal body stays fixed in its bore while its sealing lip contacts the rotating shaft. This holds lubricant in and keeps contaminants out.
- Rigid metal case: The body is formed from deep-drawn sheet steel to create a rigid, stress-resistant case.
- Dirt and water protection: Designed to give superior protection against dirt and water.
- Garter spring: The garter spring is made from cold-drawn steel wire for fluid retention.
- Correct fit: Manufactured from a tested design and quality materials for a correct fit.
SKF invented the first integrated shaft seal in 1928 and has kept developing new seal designs and bonding techniques since then. Its seals are made to specific designs using premium materials chosen to suit both the application and its operating environment.
Signs this seal may need replacing include gear oil seeping around the pinion, wetness where the driveshaft meets the differential, or a low lubricant level. Confirm the source of the leak before replacing parts.
