This is the seal in the front of the Transfercase where the Gearbox Output shaft pokes through, creating a crucial seal where the gearbox output shaft enters the housing to prevent fluid leaks.
Over time and with exposure to constant heat cycles, the original rubber seal can become hard, brittle, and crack, losing its ability to contain the transfer case oil. A leaking input seal is a common issue, and replacing it with a high-quality genuine component is the correct way to ensure a durable, long-lasting repair and prevent potential damage from oil starvation.
Replacing this seal is a moderate-level workshop job that requires access to the transfer case, which may involve removing driveshafts or the case itself. It is not recommended for novice mechanics. When replacing the seal, it's essential to top up the transfer case with the correct fluid to replace any that was lost. This is also the ideal time to inspect other nearby gaskets and seals for any signs of wear or damage.
