This ensures long-lasting performance in demanding driveline environments. The seal features a counter-clockwise spiral lip design that enhances sealing efficiency by directing contaminants away from the shaft interface. With precise dimensions including a 1.890-inch inside diameter and a 3.358-inch outside diameter, this seal fits securely within the housing bore of 3.346 inches, providing a tight, leak-resistant fit.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis differential pinion seal is compatible with various INFINITI and Nissan models, including the Armada, Pathfinder, QX56, and TITAN. It is designed to replace worn or damaged seals in the differential pinion area, helping to maintain proper lubrication and prevent fluid leaks that can lead to driveline damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePrevents oil leaks in the differential pinion area\u003c\/li\u003e\n\u003cli\u003eProtects against dirt and debris contamination\u003c\/li\u003e\n\u003cli\u003eMaintains proper lubrication for differential gears\u003c\/li\u003e\n\u003cli\u003eReduces risk of driveline component wear\u003c\/li\u003e\n\u003cli\u003eEnsures smooth operation of the differential assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the National 710920 differential pinion seal, ensure the housing bore and shaft surfaces are clean and free of debris. Proper alignment during installation is critical to avoid seal damage and ensure effective sealing. Use appropriate tools to press the seal evenly into the housing bore without distortion. Verify the seal’s orientation matches the counter-clockwise spiral lip design for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eNational manufactures the 710920 differential pinion seal to meet industry standards for durability and performance.
