Detailed Product Description

The National 710587 wheel seal is constructed from nitrile, a synthetic rubber known for its excellent resistance to petroleum-based oils and high temperatures. This ensures long-lasting performance in the driveline and axle assembly of Mercedes-Benz G-Class vehicles. The seal’s precise dimensions, including a 3.465-inch shaft diameter and a 4.250-inch outside diameter, provide a secure fit within the housing bore of 4.134 inches, minimizing the risk of leaks. The overall width of 0.394 inches, with an additional side lip width of 0.433 inches, enhances sealing capability by maintaining contact pressure and preventing contaminants from entering the axle assembly.
