NISSAN 08024-6851A Front Trailing Arm Bolt

The Nissan genuine part number 08024-6851A is an authentic OEM hex fastening bolt (BOLT-HEX) designed to provide a secure and precise connection for the front mounting point of the trailing arm within the suspension system. This suspension component plays a critical role in handling driving dynamic forces, acceleration and braking torques, as well as lateral and longitudinal loads.

Technical Specifications and Features

• Part type: Hex fastening bolt (BOLT-HEX)
• Manufacturer: Nissan (Original Equipment Manufacturer)
• Application: Chassis suspension, trailing arm mounting
• Material grade: High-tensile, hardened alloy steel
• Corrosion protection: Surface treatment resistant to weather and road salt
• Design: Shank and metric thread optimized for high shear and tensile loads

Function and Importance

The trailing arm bolt firmly secures the inner metal sleeve of the suspension bushing to the vehicle body or subframe. Because wheel alignment and suspension geometry depend directly on this mounting point, the mechanical integrity of the bolt is essential for maintaining straight-line stability, predictable cornering behavior, and uniform tire wear.

Wear and Failure Symptoms

Suspension fasteners are subject to continuous vibration, high dynamic stress, and environmental exposure. Typical wear patterns and symptoms include:

• Surface and thread corrosion, potentially leading to bolt seizure or shearing during maintenance
• Material fatigue, stretching, or deformation caused by severe mechanical impacts (e.g., potholes)
• Knocking or metallic rattling noises from the suspension over uneven road surfaces and during acceleration or braking
• Unstable handling or vehicle wandering if the fastener becomes loose

When replacing the suspension bushing or trailing arm, installing a new mounting bolt tightened to the manufacturer's specified torque is highly recommended to eliminate the risks associated with fastener elongation and fatigue.
