TOYOTA 52201-60021 Body Mount Cushion Sub-Assembly

This genuine Toyota (OEM) body mount cushion sub-assembly (Cushion Sub-Assy) is a premium-quality, precision-engineered component that plays a key role in the structural integrity and ride comfort of body-on-frame vehicles. Its function is to provide a flexible yet stable connection between the vehicle chassis (frame) and the body structure (body or cab).

Key Functions and Features:

• NVH (Noise, Vibration, and Harshness) Reduction: Effectively absorbs vibrations from road irregularities and the drivetrain, minimizing noise transmitted into the cabin.
• Structural Protection: Prevents direct metal-to-metal contact and friction, thereby protecting the body from stress cracks and premature fatigue failure.
• Durable Material Composition: Made of specialized, high-density vulcanized rubber that resists ozone, UV radiation, mud, road salt, and extreme temperature fluctuations.
• Metal Reinforcing Sleeve: The integrated steel inner bushing ensures accurate torque tightening of the mounting bolt and prevents over-compression of the rubber during installation.

Technical Specifications:

• Manufacturer: TOYOTA (Original Equipment Manufacturer)
• Part Number: 52201-60021
• Part Type: Body Mount Cushion / Vibration Damper Mount (Cushion Sub-Assy)
• Material: Heavy-duty elastomer (rubber) with metal insert

Typical Signs of Wear and Failure:

Body mount cushions are subjected to continuous loads and environmental exposure, degrading over time. Typical symptoms indicating the need for replacement include:

• Visually evident cracking, crumbling, or severe rubber deterioration (dry rot).
• Metallic knocking, squeaking, or rubbing noises, especially over rough surfaces or during cornering.
• Visible body sag or altered panel gaps between body components (e.g., fenders, doors).
• Increased vibration and road noise inside the passenger cabin.

To maintain safe and comfortable driving performance, timely replacement of worn cushions is recommended, preferably per axle or as a complete set, using genuine OEM-quality components.
