TOYOTA 90560-12233 Body Mount Bushing Spacer

The genuine TOYOTA (SKU: 90560-12233) body mount bushing spacer is a critical, precision fastening and spacing component responsible for the stability of the connection between the vehicle chassis and body. This metal sleeve sits inside the bore of the body mount rubber bushings, ensuring accurate alignment of the mounting bolts and proper distribution of clamping force.

Key Technical Features and Functions:

• Precise Spacing: Prevents excessive compression of rubber or polyurethane damping elements when tightening the mounting bolt, guaranteeing elasticity and vibration dampening that meet factory specifications.
• Structural Stability: Minimizes lateral and longitudinal play between the body and the chassis, improving driving stability and cornering characteristics.
• Durable Material Quality: Manufactured from high-tensile steel with a corrosion-resistant coating that withstands continuous dynamic loads, moisture, mud, and road salt.
• Vibration Damping Support: Helps isolate the passenger compartment from vibrations and noise originating from the suspension and drivetrain.

Common Symptoms of Wear or Failure:

• Metallic knocking or rattling noises: Especially noticeable on uneven road surfaces or during cornering if the spacer is deformed or weakened by corrosion.
• Increased cabin vibration: Occurs when the body mount can no longer effectively dampen vibrations due to spacer wear.
• Visible corrosion or deformation: Rusting, cracking, or deformation of the spacer, which compromises mounting integrity.

For safe and comfortable driving, regular inspection of the body mounts and spacers is recommended, replacing them with genuine TOYOTA parts whenever necessary.
