Product Details

National 4762N is engineered as a rear wheel seal for axle and hub sealing applications where oil retention and contamination control are critical. The seal measures 1.618 inches inside diameter, 2.849 inches outside diameter, and 0.500 inches wide, with a 3.179-inch flanged outside diameter. Its bi-directional lip design supports consistent sealing performance, while the Redi-Coat finish helps promote proper seating during installation. This part number is commonly used on rear applications for Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade, Chevrolet Tahoe, and related GM platforms.

This part cross-references Beck/Arnley 052-4061 and Bosch 16146 for the same application. National 4762N is a direct-fit style replacement for many rear axle seal service jobs across GM light-duty trucks and SUVs.

What It Is Used For

• Stopping gear oil from leaking at the rear axle seal area
• Reducing contamination from dirt, water, and road debris
• Addressing seepage around the wheel end or axle housing
• Restoring sealing performance during differential or axle service
• Supporting maintenance on rear axle assemblies in GM trucks and SUVs

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Clean the axle housing and sealing surface thoroughly, and inspect the shaft for wear, grooves, or corrosion that could affect seal life. Use proper seal installation tools to keep the seal square in the bore and avoid damaging the lip. Confirm rear axle configuration and ring gear notes for exact vehicle matching, especially on Silverado 1500, Sierra 1500, Tahoe, and Escalade applications.
