Help keep transfer case lubricant in and road grime out with the Schaeffler Transfer Case Output Shaft Seal SS3111. It is a direct-fit replacement for the 1978-1979 Ford Bronco and the 1979 Ford F-100, F-150, F-250 and F-350. The catalog lists it for both front and rear output positions.
This seal sits where an output shaft exits the transfer case. Its body stays stationary in the housing while its sealing lip rides on the rotating shaft. This helps hold lubricant inside and keep dirt, dust and moisture out. See the Buyer's Guide tab for engine-level fitment details.
