NISSAN 43210-01J10 Rear Outer Wheel Bearing

The genuine NISSAN (SKU: 43210-01J10) rear outer wheel bearing (BRG RR WHEEL OU) is a premium quality, precision-engineered suspension component that ensures smooth, low-friction rotation of the rear wheel hub while withstanding both radial and axial loads resulting from vehicle weight and cornering forces.

Technical Features and Construction

This rear outer wheel bearing is manufactured to the strictest OEM standards, guaranteeing a perfect fit and long service life. Key technical features of the bearing include:

• Heavy-duty steel alloy: Crafted from specially heat-treated, high-carbon chromium steel for maximum wear resistance and fatigue strength.
• Precision rolling elements: Micron-accurate machining of the internal rolling elements (balls or rollers) minimizes rolling resistance and operating noise levels.
• Specialized sealing system: Provides effective protection against moisture, dust, mud, and road salt while keeping high-temperature resistant lubricating grease sealed inside.
• Factory pre-lubricated: Pre-packed with durable, high-performance synthetic bearing grease that provides optimal lubrication across a wide operating temperature range.

Role and Importance of the Wheel Bearing

The rear wheel bearing is a safety-critical component. It provides a direct connection between the rotating wheel hub and the stationary suspension components. A properly functioning bearing is essential for stable road holding, precise handling, and effective braking.

Typical Symptoms of Failure

Wheel bearings are subject to natural wear and tear. Common symptoms of failure include:

• Deep humming, rumbling, or growling noise: Increases with vehicle speed and changes pitch or intensity when cornering.
• Wheel play (looseness): A worn bearing can lead to excessive wheel play, compromising straight-line stability.
• Increased vibration: Noticeable vibrations transmitted through the steering wheel or vehicle body.
• Abnormal tire wear: Irregular wheel alignment caused by bearing wear leads to uneven tire wear.

To ensure driving safety, a failed or worn wheel bearing should be replaced immediately. Using genuine Nissan parts restores the vehicle's original driving dynamics and safety standards.
