Detailed Description

National 710694 is an oil seal for transfer case output shaft service, engineered around precise metric dimensions for proper housing and shaft fitment. The seal measures 54.000 mm inside diameter, 75.200 mm outside diameter, and 12.500 mm thickness, with a 75.000 mm housing bore and 81.000 mm flanged outside diameter. Its fluoro-elastomer construction is suited to sealing applications where heat and fluid exposure are part of normal operation.

This part number is used across multiple 4WD platforms, including 2011-2018 Dodge Durango and Jeep Grand Cherokee models with Magna 3023 transfer cases, 2005-2010 Jeep Grand Cherokee and 2006-2010 Jeep Commander with New Process transfer cases, and 2017-2019 Nissan TITAN and 2016-2019 Nissan TITAN XD with Magna TX91A transfer cases. It also applies to 2016-2019 Cadillac CT6 and 2008-2009 Chrysler Aspen transfer case configurations. National has supplied sealing solutions for decades, and this seal reflects that focus on dimensional accuracy and drivetrain sealing performance.

What It Helps Address

• Transfer case fluid leakage at the output shaft
• Oil seepage around the transfer case housing bore
• Seal wear from shaft rotation and driveline heat
• Service issues on front or rear transfer case output locations
• Replacement needs during transfer case maintenance or rebuild work

Installation Notes and Tips

Verify shaft diameter, housing bore, and transfer case type before installation. Clean the bore and shaft sealing surface thoroughly, and inspect for grooves, corrosion, or contamination that could affect sealing. Confirm whether the vehicle uses a front or rear transfer case output position, since fitment varies by application. For best results, match the seal to the exact transfer case configuration listed for the vehicle.
