Help keep lubricant sealed inside the transmission or differential with the SKF Automatic Transmission Output Shaft Seal / Differential Seal 14129. It is a direct-fit replacement for many Ford, Mercury and Mazda applications, among them the 1991-2003 Ford Escort, 1994-1997 Ford Aspire and 1989-1997 Ford Probe; see the "Vehicles it fits" section for the full list. This part is listed under both names, output shaft seal and differential seal. Depending on the application, it is cataloged for the rear, front right and front left positions.
- Rigid metal case: The body is formed from deep drawn sheet steel, which creates a rigid, stress-resistant case.
- Steel garter spring: The garter spring uses cold drawn steel wire to help the sealing lip hold fluid in.
- Dirt and water protection: The seal is designed to guard against dirt and water.
- Correct fit: SKF uses a tested design and quality materials to achieve a correct fit.
The seal body stays stationary while its lip contacts the rotating shaft. It works to keep lubricant in and contaminants out. Signs this seal may need replacing include fluid seeping or dripping around the output shaft or axle area, or a steadily dropping fluid level. Nearby seals and gaskets can also leak, so confirm where the leak is coming from before you replace this seal.
SKF invented the first integrated shaft seal in 1928. The company has continued to develop new seal designs and bonding techniques, and it builds each seal to a specific design using premium materials chosen for the application and its environment.
