Bushings are vital suspension components that cushion and absorb vibrations between metal parts in a vehicle’s suspension and chassis systems. They consist of an outer metal casing and an inner lining made of materials like rubber or polyurethane, designed to isolate vibrations and reduce noise and shocks. Over time, bushings can wear out due to constant movement and exposure to road conditions and temperature changes, leading to increased noise, vibration, or decreased handling responsiveness. Regular inspection and timely replacement of worn bushings, typically recommended every 80,000 to 160,000 kilometers (50,000 to 100,000 miles), are essential to maintain optimal suspension performance and ensure a smoother, quieter driving experience.
