NISSAN 54476-01J00 Front Control Arm Rear Rubber Bushing

The genuine NISSAN part number 54476-01J00 is a premium-quality front control arm rear rubber bushing (BUSHING-RUBBER), serving as an essential structural element of the vehicle's front suspension. This rubber-to-metal bushing provides a flexible yet stable connection between the front control arm and the vehicle chassis or subframe.

Function and Operating Principle

The primary function of the control arm bushing is to absorb and damp dynamic forces, vibrations, and road shocks originating from the chassis. As a result, it minimizes noise and vibration transmitted to the vehicle body and passenger cabin. Furthermore, it enables guided rotation of the control arm about a defined axis while preventing unwanted radial and axial play, maintaining precise suspension geometry.

Technical Specifications

• Fitting Position: Front axle, front control arm rear section (applicable to both left and right sides depending on vehicle specification).
• Material Composition: High tensile strength vulcanized elastomer (rubber) and precision steel sleeve.
• Resistance: Excellent resistance against ozone, UV radiation, mud, road salt, and engine oils.
• Design: Rubber-to-metal bearing engineered with an optimal stiffness characteristic to balance comfort and stable road handling.

Common Symptoms of Wear and Failure

Rubber bushings are subjected to continuous mechanical and environmental stresses, leading to aging and degradation over time. Common symptoms of failure include:

• Knocking, rattling, or squeaking noises from the suspension, particularly on uneven surfaces or during cornering.
• Imprecise, wandering steering feel and degraded straight-line stability.
• Abnormal, uneven tire wear caused by altered toe and camber alignment.
• Visible cracks upon visual inspection, crumbling rubber material, or separation of the rubber from the metal sleeve.
