Technical Details and Material Specifications

This differential pinion seal from National is constructed from fluoro-elastomer, a material known for its resistance to heat, oil, and other automotive fluids, ensuring long-lasting durability in demanding driveline environments. The seal features a clockwise-spiral lip design that optimizes sealing against the rotating shaft, minimizing the risk of leaks. With an inside diameter of 1.890 inches (48 mm) and an outside diameter of 3.171 inches (80.350 mm housing bore), it fits precisely within the differential housing bore of compatible Nissan models. The thickness of 0.522 inches (13.250 mm) and an overall width including the side lip of 0.758 inches (19.250 mm) provide a secure fit and effective sealing surface.

Compatible Nissan Models and Applications

This National 711069 differential pinion seal is compatible with a range of Nissan vehicles, specifically designed for the Armada, Frontier, Pathfinder, TITAN, and Xterra. It is intended for use in the driveline and axle assemblies where maintaining differential oil containment is critical for proper vehicle operation and longevity.

• Prevents differential oil leaks that can cause driveline damage
• Protects against contamination from dirt and debris entering the differential
• Maintains proper lubrication for differential gears and bearings
• Helps reduce wear and extend the service life of differential components
• Ensures smooth and reliable driveline performance

Installation Notes and Tips

When installing the National 711069 differential pinion seal, ensure the housing bore is clean and free of debris to prevent damage to the seal lip. Use appropriate tools to press the seal evenly into place without distortion. Verify the seal orientation matches the clockwise-spiral lip design for optimal sealing. Proper installation will help avoid premature leaks and maintain differential performance.
