NISSAN 40010-VB200 Right Steering Knuckle Assembly

The genuine OEM part with part number NISSAN 40010-VB200 is an authentic, premium-quality right-hand steering knuckle assembly (KNUCKLE ASSY,RH), representing one of the most critical structural components of the vehicle's front suspension and steering system. This component provides the direct link between the wheel hub, suspension control arms, shock absorber, and steering gear, enabling precise wheel pivoting and stable road holding.

Function and Importance in the Suspension System

The steering knuckle plays a crucial role in safe vehicle handling and structural integrity:

• Load Transmission and Mounting: Securely supports the wheel hub and wheel bearing while providing a stable mounting point for the brake caliper and shock absorber.
• Steering: Receives motion from the steering gear via the tie rod end, directly controlling the wheel's steering angle.
• Suspension Integration: Connects the upper and lower control arms (or MacPherson strut assembly), allowing vertical suspension movement to absorb road imperfections.

Technical Characteristics and Material Quality

Because the steering knuckle is subjected to continuous high mechanical loads, vibrations, and environmental impacts, it is manufactured according to strict NISSAN factory standards:

• Material: High-strength cast iron or forged steel alloy for maximum torsional rigidity and resistance to fatigue cracking.
• Fitting Position: Front axle, right-hand side (RH - Right Hand).
• Precision Machining: Bearing seats and ball joint tapers are machined with micrometer precision to ensure perfect fitment and play-free operation.
• Corrosion Protection: Coated with a specialized surface treatment to resist corrosion from mud, moisture, and de-icing road salts.

Signs of Failure or Wear

Although the steering knuckle is an exceptionally robust component, severe physical impacts (such as striking a deep pothole, hitting a curb, or being involved in a collision) can cause deformation or cracks. Common symptoms of failure include:

• Abnormal, uneven tire wear caused by altered suspension geometry (camber or toe misalignment).
• Vehicle pulling to one side while driving on a straight road.
• Vague steering feel or inability to properly align the suspension.
• Visually apparent cracks, bends, or thread damage at mounting points.

Attempting to repair a damaged or bent steering knuckle is not recommended; for safe vehicle operation, the unit should be replaced immediately with a genuine factory-grade replacement.
