Why Does the BMW 3 Series Buffer Rubber Make Abnormal Noises?

[StDamian]

The reasons for abnormal noises in the BMW 3 Series buffer rubber include buffer rubber aging and shock absorber issues. Buffer Rubber Aging: When the shock absorber buffer rubber shows signs of aging, the vehicle may produce noises when driving over bumpy roads, and the comfort of the vehicle may also deteriorate. The connection between the shock absorber and the car body has buffer rubber, which can improve the vehicle's comfort. However, rubber products will age over time with prolonged use. Shock Absorber Issues: If the rubber components such as the shock absorber top rubber, arm bushings, and stabilizer bar links age and harden, they may produce squeaking noises when squeezed. A faulty damper can also cause abnormal noises in the shock absorber. Leakage of air or oil in the shock absorber is inevitable as it is a wearable part of the car.
