Product Description
This genuine NISSAN (SKU: 43262-VC20A) rear stub axle lock nut is a safety-critical suspension and driveline component responsible for the secure, play-free fastening of the rear wheel hub assembly and axle shaft to the spindle.
Function and Technical Significance
The primary function of the rear stub axle nut is to establish and maintain the precise axial preload of the wheel bearing. The "NUT-LOCK" (self-locking) design ensures that the component maintains its factory-specified tightening torque despite continuous vibrations, dynamic loads, and thermal fluctuations. The self-locking mechanism prevents unintentional backing off, which would directly jeopardize vehicle stability and handling safety.

- Surface Treatment: Protective anti-corrosion coating against environmental exposure and road salt
- Locking Method: Self-locking collared design
Maintenance and Installation Guide
For safety reasons, stub axle nuts are classified as single-use components. Following any service procedure involving the disassembly of the wheel hub or axle shaft (e.g., wheel bearing replacement, CV joint/axle shaft service), the nut must be replaced with a new genuine unit. Reusing a spent nut compromises the integrity of its locking feature, potentially resulting in loosening under driving conditions. During installation, the manufacturer's specified tightening torque must be strictly adhered to (the use of a calibrated torque wrench is mandatory; impact wrenches must never be used for final tightening).
Signs of Failure or Wear
- Damaged, stretched, or stripped threads observed during inspection or removal.
- Cracks, fatigue, or deformation on the locking collar/crimp flange.
- Heavy surface corrosion hindering precise torque application.
- Wheel bearing play or a groaning/humming noise caused by insufficient bearing preload due to loosening.
