Product Overview

National 710691 is an oil seal for the transfer case output shaft, engineered around the listed shaft and housing dimensions for a precise service replacement. The fluoro-elastomer sealing material is selected for drivetrain sealing demands, while the spiral lip design supports sealing at the rotating shaft interface. For Jeep Grand Cherokee models with the specified New Process transfer cases, this seal addresses the rear output location where fluid retention is critical.

What This Seal Helps Address

• Transfer case fluid seepage at the output shaft
• Oil residue around the rear transfer case area
• Seal wear from shaft rotation and age
• Loss of sealing integrity at the housing bore
• Service replacement needs on Jeep Grand Cherokee 4WD transfer cases

Installation Notes and Tips

Verify the transfer case model, shaft diameter, housing bore, and rear position before installation. Clean the bore and shaft sealing surface thoroughly, and inspect for grooves, corrosion, or damage that could affect seal life. Confirm the seal orientation matches the application and press it in evenly to avoid distortion.
