TOYOTA 48702-35070 Rear Lower Control Arm Bushing

The genuine TOYOTA 48702-35070 rear lower control arm bushing (BUSH SUB-ASSY) is a premium quality, original component responsible for the optimal operation of the vehicle's rear suspension system. The bushing plays a vital role in providing a flexible yet stable mounting for the rear lower control arm, ensuring proper suspension geometry and stable roadholding.

Technical Specifications and Construction

• Material Composition: Heavy-duty vulcanized natural rubber and precision inner and outer steel sleeves. The rubber compound is specifically formulated to resist ozone, road salt, moisture, and extreme temperature fluctuations.
• Fitting Position: Rear suspension, lower control arm (trailing arm) mounting point.
• Primary Function: Absorption of dynamic shocks and vibrations from the suspension, prevention of metal-on-metal contact, and provision of controlled control arm movement.

Role and Importance of the Bushing

The rear lower control arm bushing directly affects vehicle driving dynamics and safety. During operation, the suspension is subjected to continuous stress; the function of the bushing is to dampen longitudinal and lateral forces transmitted from the wheels. The genuine Toyota part guarantees the factory-specified balance of stiffness and elasticity, preserving the vehicle's original handling characteristics.

Common Symptoms of Wear and Failure

Over time, rubber components age and lose their elasticity due to continuous stress and environmental exposure. The most common signs of failure include:

• Knocking, metallic, or squeaking noises from the rear suspension, particularly over uneven road surfaces or speed bumps.
• Imprecise, vague steering response and instability during cornering.
• Abnormal, uneven wear on the rear tires.
• Visible cracks or tears in the rubber body during visual inspection, or complete debonding of the rubber from the metal sleeve.

To ensure safe driving and protect other suspension components, timely replacement of worn bushings is essential. Using genuine TOYOTA parts ensures maximum service life and a perfect fit.
