Schaeffler Transfer Case Output Shaft Seal P/N:SS2619
Help keep lubricant inside the transfer case and road grime out with the Schaeffler Transfer Case Output Shaft Seal SS3123. This rear output shaft seal is a direct-fit replacement for the 1973-1974 GMC K15/K1500 Pickup and Suburban, K25/K2500 Pickup and Suburban, and K35/K3500 Pickup. See the "Vehicles it fits" section for engine-specific details.
The seal body stays stationary in the transfer case housing while its lip rides against the turning output shaft. This forms a barrier designed to hold lubricant in and keep contaminants away from the shaft and internal components.
Signs this seal may need replacing include fluid seeping or dripping from the rear of the transfer case, an oily film around the rear output area, or a transfer case fluid level that keeps dropping. Other seals and gaskets can leak in the same area, so diagnose the leak source before replacing.
