Car bushings are small rubber or polyurethane suspension components that are used to isolate vibration, provide cushioning, and reduce friction between metal parts on your vehicle.
Life expectancy of bushings depends on the location, and materials such as rubber vs polyurethane.
Damaged bushings can trigger clunking and creaking when you increase the car’s speed or turn a sharp corner. Going further regarding a worn bushing, this damaged component weakens the bond between two car parts. The weak connection results to misalignment. Every time the misaligned parts return to their original positions as the vehicle moves, they make clunking noises which are noticeable due to the rhythmic movement of the car.
