NISSAN 40262-02J10 Front Wheel Bearing Lock Nut

The genuine OEM NISSAN 40262-02J10 front wheel bearing lock nut (NUT-LOCK FRONT) is a critical safety fastening component in the vehicle suspension and running gear system. This precision-threaded nut secures the front wheel bearing and wheel hub assembly to the spindle/stub axle, maintaining the correct bearing preload and preventing axial movement during operation.

Technical Specifications and Features:

• Manufacturer: NISSAN (Genuine OEM part)
• Part Type: Front Wheel Bearing Lock Nut (Nut-Lock Front)
• Material Quality: High-strength, heat-treated structural steel engineered to endure extreme mechanical stress and vibration.
• Surface Protection: Specialized anti-corrosion coating to resist rust and degradation caused by moisture, mud, and road salts.
• Locking Mechanism: Self-locking or mechanically stakeable design that ensures the nut does not back off or loosen under rotational forces and vibration.

Why Genuine Quality Matters & When Replacement is Necessary:

The wheel bearing lock nut is subject to immense rotational and axial loads. Using a substandard or worn lock nut can result in premature wheel bearing failure or, in severe cases, wheel hub detachment while driving.

• Single-Use Component: According to manufacturer guidelines, the lock nut must be replaced with a new genuine component every time it is loosened (e.g., during wheel bearing replacement or drive axle servicing). The locking collar or thread deforms permanently upon initial tightening, making reuse unsafe.
• Signs of Wear: Thread damage, cracking or deformation of the locking collar, severe surface corrosion, or loss of torque retention.
• Installation Recommendation: Always tighten to the manufacturer's exact specified torque (Nm) using a calibrated torque wrench.
