A bushing, also known as rubber bushing, is a type of vibration isolator. By acting as a cushion between parts and reducing the amount of movement in the joints. any bushing reduces road noise, vibration, and harshness. On the contrary, bushings wear out and allow more movement.  It is a small rubber or polyurethane suspension component used to isolate vibration, offer to cushion, and minimize friction between metal parts on the vehicle. It also acts as an interface between two pieces, functioning as a buffer and absorbing some of the energy generated by interaction.

Additionally, other bushings can be made of bronze, steel0backed babbit, plastic, nylon, or cast iron. Bronze is a common choice for bushings because it comes in alloys and compositions to be used in a wide range of applications, Bronze bushings are more durable than other materials and are less likely to crack or distort. Among other materials, the bushing materials must be able to support and protect the component.

Signs of Damaged Bushings

  • Clunking or scraping noises
  • Uneven tire wear
  • Poor braking performance and handlings
  • Poor steering effort or sluggish steering condition
