TOYOTA 48702-60100 Rear Lower Control Arm Bushing

The genuine Toyota 48702-60100 rear lower control arm bushing (Bush Sub-Assy) is a critical suspension component responsible for vehicle rear suspension stability, maintaining wheel alignment geometry, and dampening vibrations. Precise manufacturing tolerances characteristic of genuine OEM parts guarantee a perfect fit and long service life.

Technical Characteristics and Construction

This rubber-to-metal bushing is constructed from a specially engineered elastomer (rubber) compound and high-strength steel inner and outer sleeves. The rubber component is securely bonded to the metal parts using vulcanization technology, delivering the required torsional rigidity and optimal absorption of radial and axial forces.

• Fitting Position: Rear axle, lower control arm
• Part Type: Rubber-to-metal bushing (Bush Sub-Assy)
• Material Composition: High-tensile steel and weather-resistant vulcanized rubber
• Resistance: Excellent resistance to environmental elements (moisture, road de-icing salt, temperature fluctuations)

Role and Function of the Bushing

The rear lower control arm bushing connects the control arm to the vehicle chassis or subframe. Its purpose is to allow controlled articulation of the control arm during suspension travel while preventing unwanted lateral movement. This directly contributes to straight-line tracking stability and cornering control.

Symptoms of Wear and Failure

Suspension bushings are subjected to continuous dynamic loads, causing them to degrade and wear over time. Common symptoms of failure include:

• Knocking, rattling, or squeaking noises from the rear suspension, especially when driving over rough road surfaces or speed bumps.
• Vague, imprecise steering response and vehicle instability during cornering.
• Abnormal, uneven rear tire wear resulting from altered suspension alignment geometry.
• Visually evident cracks, crumbling rubber material, or complete separation from the metal sleeve during inspection.

To ensure driving safety and prevent premature wear on related suspension components, timely replacement of worn bushings is essential. Installing a genuine Toyota component restores the vehicle's original factory driving dynamics and ride comfort.
