Automotive bearings bushing are small suspension components that reduce friction between metal parts of the vehicle. They are made of a self-lubricating material (usually bronze) and are critical to ensuring a smooth ride. While they are not the only reason you can shake, they are usually the prime suspect. For something that makes such a big difference, bronze bushings are very simple. They consist of just two parts: the outer (usually bronze) bushing and the spongy interior. But, like most suspension components, they don’t last forever.

Because their self-lubricating suspension automotive bearings life varies greatly depending on driving style and environment, there is no set suspension bushing replacement interval. Instead, automotive bearings technology engineers recommend that you replace them when you notice the following symptoms.

• Excessive road noise and vibration in the vehicle
• Unusually loose steering and a noticeable lack of control
• Thumping or squealing noises around the fenders
• Frame rattling when driving over rough terrain
