Suspension bushings are rubber or polyurethane components used in a vehicle's suspension system. They act as cushions between various parts, such as the control arms and the chassis, helping to absorb shocks and vibrations from the road. This enhances ride comfort and improves handling by allowing for controlled movement of the suspension components. These bushings also help reduce noise and wear on the suspension parts. Over time, they can wear out or become damaged, leading to issues like a rough ride or poor handling. Regular inspection and replacement of suspension bushings are essential for maintaining vehicle performance and safety.
