NISSAN 43232-01J10 Rear Wheel Bearing Grease Seal

The genuine Nissan (OEM: 43232-01J10) rear wheel bearing grease seal is a premium-quality sealing component responsible for retaining proper lubrication and protecting the rear wheel hub assembly.

Technical Characteristics and Construction

• Material Composition: High-grade, wear-resistant, and heat-tolerant elastomer with a metal reinforcing casing to ensure a precise and secure fit.
• Sealing Technology: Specially engineered sealing lip with an auxiliary dust lip that minimizes friction while providing maximum sealing efficiency.
• Resistance: Outstanding resistance to lubricating greases, mineral oils, and external environmental factors (moisture, mud, road salt).
• Fitting Position: Rear axle, wheel hub / wheel bearing assembly.

Function and Importance of the Seal

The primary function of the rear wheel bearing seal is to retain lubricating grease within the wheel bearing while preventing external contaminants (dust, water, fine sand) from entering. If the seal becomes damaged or worn, lubricant can leak out, causing the bearing to run dry, overheat, and ultimately suffer catastrophic failure. Additionally, leaking grease can contaminate brake components, posing a direct safety hazard.

Common Symptoms of Wear and Failure

• Grease leakage or wet, oily deposits appearing on the inner side of the wheel hub.
• Metallic grinding, rumbling, or humming noises originating from the rear suspension, indicating bearing lubrication failure.
• Reduced braking performance caused by grease contamination on friction surfaces.
