TOYOTA 48702-60090 Rear Upper Control Arm Bushing

The genuine TOYOTA 48702-60090 rear upper control arm bushing (BUSH SUB-ASSY) is a critical suspension component responsible for the stability of the rear suspension system and ride comfort. This premium-quality rubber-to-metal bushing connects the rear upper control arm to the vehicle chassis or axle housing, providing the necessary flexibility during suspension movement while absorbing vibrations and shocks from the road surface.

Key Functions and Features:

• Vibration Damping: Effectively reduces noise and vibrations originating from the suspension, enhancing cabin comfort.
• Geometry Retention: Maintains precise rear wheel camber and toe angles under load, which is essential for safe cornering and straight-line stability.
• Durability: Manufactured according to genuine TOYOTA specifications, the vulcanized rubber and metal sleeve resist environmental impacts (moisture, mud, road salt) and continuous mechanical stress.

Technical Specifications:

• Part Type: Rear upper control arm bushing (Bush Sub-Assy)
• Fitting Position: Rear axle, upper control arm
• Material Composition: High-tensile, aging-resistant elastomer (rubber) and precision steel inner/outer sleeve
• Quality: Genuine OEM part, ensuring a perfect fit and extended service life

Common Symptoms of Bushing Wear:

• Knocking or squeaking noises from the rear suspension when driving on uneven surfaces.
• Vague, "floating" steering and handling behavior, especially during cornering or lane changes.
• Uneven or abnormal rear tire wear.
• Visibly identifiable cracks, tearing, or separation of the rubber from the metal sleeve upon inspection.

To ensure the safe operation of the suspension system and protect tire longevity, prompt replacement of worn bushings is strongly recommended. Installing genuine TOYOTA parts restores the vehicle's original factory ride dynamics and safety.
