Constructed from nitrile, this oil seal offers excellent resistance to petroleum-based fluids and high temperatures commonly encountered in automotive applications. The precise inside diameter of 2.700 inches (68.58 mm) and outside diameter of 3.504 inches (89.002 mm) ensure a secure fit on the axle shaft and housing bore, which measures approximately 3.499 inches (88.875 mm). The flanged outside diameter of 3.704 inches (94.082 mm) provides additional sealing surface and stability during operation. The overall width with side lip of 0.462 inches (11.73 mm) helps maintain a tight seal to prevent contamination and fluid leakage.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrevents axle oil leaks in Ford Bronco and F-150 wheel hubs\u003c\/li\u003e\n\u003cli\u003eProtects driveline components from dirt and debris ingress\u003c\/li\u003e\n\u003cli\u003eReduces wear on axle shafts by maintaining proper lubrication\u003c\/li\u003e\n\u003cli\u003eHelps avoid costly repairs due to seal failure or contamination\u003c\/li\u003e\n\u003cli\u003eMaintains optimal performance of the vehicle’s driveline system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the National 710091 wheel seal, ensure the axle shaft and housing bore are clean and free of debris. Lubricate the seal lip with appropriate axle grease to reduce initial wear during startup. Use a seal driver tool to press the seal evenly into the housing bore without distortion. Verify the seal is fully seated and the flanged outside diameter aligns properly with the hub assembly. Regular inspection during maintenance intervals can help detect early signs of wear or leakage.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eNational wheel seals, including part number 710091, are manufactured to meet industry standards for durability and performance.
