Keep gear oil in and road grime out with the SKF differential pinion seal, part number 15788. It is a direct-fit replacement for the listed applications, including the 1959-1960 International B100, 1961-1982 Checker Marathon, 1966-1996 Ford Bronco, 1970-1979 GMC Jimmy, 1975-1996 Ford F-150 and 1993-1996 Jeep Grand Cherokee. It is cataloged for both front and rear differential positions, depending on the application.
The seal sits where the pinion exits the differential housing. Its body stays stationary while its lip rides against the rotating pinion, holding lubricant in and keeping contaminants out. SKF invented the first integrated shaft seal in 1928 and has kept developing new seal designs and bonding techniques since. Its seals are built to specific designs, with premium materials chosen to suit both the application and its environment.
Signs a pinion seal may need replacing include gear oil seeping around the pinion area, drips under the differential, or a dropping fluid level. See the "Vehicles it fits" section for engine details and the full list of applications.
