Help keep differential lubricant where it belongs with the SKF differential pinion seal, part number 18136. It is a direct-fit replacement for a wide range of Ford, Mercury, Lincoln, Jaguar and Avanti applications. These include the 1983-2013 Ford F-150, 1979-2014 Ford Mustang and 1991-2010 Ford Explorer. See the "Vehicles it fits" section for the full list and engine details.
The pinion seal sits in the differential housing around the pinion shaft, where the driveshaft connects. The seal body stays stationary while its lip contacts the rotating pinion yoke or flange. It holds lubricant in and helps keep dirt and water out. Depending on the vehicle, this seal is cataloged for front or rear differential positions.
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 environment.
Signs this part may need replacing include lubricant leaking or wet residue at the pinion end of the differential housing, where the driveshaft connects. A low differential fluid level is another sign. If a worn pinion seal is the source of the leak, this seal replaces it.
