Keep transfer case fluid where it belongs and block road grit with the National Transfer Case Input Shaft Seal / Output Shaft Seal (MPN 710682). This is the FRONT shaft seal, and it drops in as a direct-fit replacement for the listed applications — including the 2003-2014 Cadillac Escalade, 2003-2014 Chevrolet Tahoe, 2003-2014 GMC Yukon, 2003-2009 Hummer H2, 2003-2006 Hyundai Santa Fe and 2003-2009 Kia Sorento — with one seal used per application. See the Buyer's Guide tab for the full 22-vehicle list.
Signs this seal may need replacing include fluid seepage or drips near the transfer case shaft and low transfer case fluid. If a leaking front shaft seal is the cause, this replaces it — diagnose the source of any leak before ordering.

What does this seal do?
It is the front transfer case shaft seal. The stationary seal body rides against the rotating input or output shaft to retain transfer case fluid and keep out dirt and moisture.
Is this a front or rear seal?
The catalog lists it as the FRONT transfer case shaft seal, serving as either the input or output shaft seal.
Will this fit my vehicle?
It is a direct-fit replacement for 22 applications, including the 2003-2014 Cadillac Escalade, Chevrolet Tahoe, GMC Yukon and Kia Sorento. Check the Buyer's Guide tab to confirm your vehicle.
How many do I need?
Quantity per application is 1, so one seal is used per vehicle. Confirm the count against your transfer case service information.
What are the signs this seal may need replacing?
Fluid seepage or drips near the transfer case shaft and low transfer case fluid. Diagnose the leak source first, since other seals or gaskets can cause similar symptoms.
