Product Description
The Nissan 43083-VC20A is a genuine OEM rear wheel bearing mounting bolt that plays a critical role in the safe and stable operation of the vehicle's running gear and suspension. This high-strength fastener is specifically engineered to secure the rear wheel bearing assembly or hub unit precisely to the axle knuckle.
Technical Features and Function
Wheel bearing mounting bolts are among the most heavily stressed fasteners in a motor vehicle. They are constantly subjected to dynamic, multi-directional physical forces (shear and tensile stresses) resulting from cornering, acceleration, and braking.
- Material Quality: Premium high-tensile hardened steel alloy that withstands structural fatigue and high tightening torques.
- Surface Treatment: A specialized anti-corrosion coating protects the component against moisture, road grime, de-icing salts, and chemical exposure, preventing premature seizure or structural weakening.
- Safety Engineering: Thread geometry and factory specifications ensure superior resistance to vibration, preventing spontaneous loosening during service.
Why Replacement Is Essential
When replacing the rear wheel bearing, renewing the mounting bolts is strongly advised and frequently mandated by service guidelines. The primary reasons include:
- Plastic Deformation (Bolt Stretch): Many modern suspension bolts are torque-to-yield fasteners that permanently elongate when torqued and angle-tightened to OEM specifications. Reusing them poses a significant risk of bolt failure or inadequate clamping load.
- Material Fatigue: Microscopic fractures and metal fatigue are invisible to the naked eye but drastically reduce the bolt's load-carrying capacity.
- Thread Damage: Removal of weathered fasteners often damages corroded threads, preventing accurate torque application and secure reinstallation.
Always adhere to the vehicle manufacturer's specified torque procedures and installation instructions during assembly to ensure the safe operation of the suspension system.
