Detailed Description

National 711069 is a differential pinion oil seal engineered around precise metric dimensions and a fluoro-elastomer sealing lip. The seal measures 1.890 inches (48.000 mm) inside diameter, 3.171 inches outside diameter, and 0.522 inches width, with a clockwise-spiral lip profile that supports controlled sealing at the pinion area. This part number 711069 is listed for rear outer positions on 2004-2015 Nissan TITAN, 2005-2015 Nissan Armada, 2005-2015 Nissan Xterra, 2005-2018 Nissan Frontier, and 2005-2012 Nissan Pathfinder when equipped with an 8.5-inch ring gear and Spicer 44 axle.

National has focused on sealing solutions for more than 75 years, and this seal reflects that experience with a design intended for modern driveline service requirements. If you are replacing a leaking pinion seal on a Nissan Frontier, TITAN, Armada, Xterra, or Pathfinder, 711069 provides the dimensional match needed for the specified axle applications.

What It Helps Address

• Differential gear oil seepage at the pinion seal area
• Visible oil residue around the rear axle pinion
• Loss of lubricant from a worn or hardened seal lip
• Service replacement for driveline maintenance on Nissan rear axles

Installation Notes and Tips

• Verify axle configuration before ordering; this seal is listed for 8.5-inch ring gear and Spicer 44 axle applications.
• Inspect the pinion shaft and housing bore for wear, scoring, or corrosion before installation.
• Clean the sealing surface thoroughly so the new lip can seat evenly.
• Confirm the housing bore and shaft dimensions match the listed metric specifications.
• Use proper driveline service procedures to set pinion preload and prevent repeat leakage.
