Detailed Description

National has supplied sealing solutions for more than 75 years, and this transfer case shift shaft seal reflects that focus on dimensional accuracy and application-specific fitment. The 471466 seal is engineered around a 15.880 mm shaft size and a 28.650 mm outside diameter, with a 28.550 mm housing bore reference. That makes it a practical replacement when servicing transfer case shift shaft leakage on older 4WD vehicles.

Installation Notes and Tips

Verify shaft diameter, housing bore, and transfer case type before installation. Clean the bore and shaft thoroughly, inspect for wear or scoring, and confirm the seal is seated squarely to the specified depth. Use care during installation to avoid damaging the nitrile lip or the Redi-Coat sealing surface. For Jeep CJ5, CJ7, Scrambler, Wagoneer, Bronco, Blazer, Jimmy, and F-100 service, confirm the transfer case configuration listed in the fitment notes before ordering.
