NISSAN 55045-VB200 Control Arm Bushing

The genuine NISSAN 55045-VB200 control arm bushing (also known as a spring bushing or rubber-to-metal silent block) is a critical component of the vehicle's suspension system. Its primary role is to provide a flexible joint between moving suspension parts while effectively isolating and damping road vibrations, impacts, and noise.

Technical Characteristics and Construction

Manufactured to strict OEM standards, this premium-quality genuine component guarantees precise fitment and long service life. Key features include:

• Material Composition: A combination of a high-strength steel sleeve and a specialized vulcanized elastomer (rubber) compound resistant to weathering, ozone, and mechanical fatigue.
• Design: Bonded rubber-metal sleeved construction engineered to deliver optimal torsional stiffness as well as radial and axial damping.
• Reference Numbers: NISSAN 55045-VB200, NAB072 (replacement/aftermarket code).

Role and Operation

Control arm bushings directly impact driving stability and ride comfort. They maintain suspension geometry within engineered tolerances under dynamic load, which is essential for accurate steering response and uniform tire wear.

Typical Symptoms of Wear or Failure

Over time, rubber components degrade due to environmental factors (temperature fluctuations, road salt, moisture) and continuous mechanical stress. Common signs of wear include:

• Knocking, rattling, or squeaking noises from the suspension, particularly over uneven road surfaces or when cornering.
• Vague, imprecise steering response and deteriorated straight-line tracking.
• Abnormal or one-sided tire wear caused by altered suspension alignment.
• Visible cracking, rubber embrittlement, or complete separation from the metal sleeve upon visual inspection.

To maintain vehicle safety and prevent premature wear on related suspension components, damaged or aged bushings should be replaced promptly.
