NISSAN 82421-2J00A Rear Door Hinge Assembly

The genuine Nissan rear door hinge assembly (part number: 82421-2J00A) is a premium-quality, original OEM body component designed to ensure secure mounting and precise operation of the vehicle's rear door. Installing genuine factory parts guarantees a perfect fit, compliance with factory tolerances, and a long service life, avoiding the installation inaccuracies often encountered with aftermarket alternatives.

Key Functions and Importance

The hinge mechanism plays a crucial role in the vehicle's structural integrity and everyday comfort:

• Precise Door Alignment: Ensures smooth, unobstructed movement of the rear door during opening and closing cycles.
• Structural Support: Properly distributes the weight of the door, preventing sagging that could damage the latch assembly and body weatherstripping.
• Noise and Weather Sealing: Maintains proper contact against the door seals through accurate positioning, minimizing wind noise and preventing moisture from entering the passenger compartment.

Common Symptoms of Wear or Failure

Over time, mechanical stress and environmental exposure can lead to hinge wear. The need for replacement is indicated by the following symptoms:

• The door is difficult to close or must be lifted upward to latch properly.
• Metallic clicking, squeaking, or rubbing noises during door operation.
• Visibly uneven gaps between the closed door and adjacent body panels.
• Excessive play or looseness in the hinge pins and bushings.
