NISSAN 90410-VB06A Rear Door Hinge

The genuine NISSAN rear door hinge (part number 90410-VB06A) is a premium-quality OEM component designed to ensure secure mounting and precise, smooth operation of the vehicle's rear door (tailgate/back door). The hinge plays a critical role in maintaining structural door integrity, ensuring precise panel alignment, and preserving proper sealing against water ingress and wind noise.

Technical Specifications and Features:

• Material: High-strength, hardened steel alloy for maximum load-bearing capacity and resistance to deformation.
• Surface Treatment: Specialized anti-corrosion and rust-resistant protective coating designed to withstand weathering and moisture.
• Design: Engineered to OEM specifications, guaranteeing a perfect fit and accurate alignment with factory mounting points.
• Operation: Reduced-friction pivot points for smooth, quiet opening and closing of the door.

Hinge Function and Signs of Wear:

Rear door hinges are subjected to continuous mechanical stress and environmental exposure. Over time, hinges can wear out, leading to the following symptoms:

• Door Sagging: Hinge wear causes the door to misalign with the body, resulting in difficult closing or premature wear of the latch mechanism.
• Abnormal Noises: Squeaking, clicking, or grinding noises when opening or closing the door, indicating a lack of lubrication or worn internal bushings.
• Visible Rust or Play: Excessive play (looseness) in the hinge pin or surface corrosion weakens the structure, potentially creating a safety hazard.

To ensure road safety and maintain vehicle value, worn or damaged hinges should be replaced promptly with genuine OEM parts.
