Why Does the Shock Absorber Make Metal Noise When Cold but Not When Hot?
1 Answers
This situation usually occurs due to oil leakage from the shock absorber or damage to the shock absorber itself. The owner can inspect it themselves or visit a professional 4S shop or repair shop for inspection and maintenance, which may involve replacing the shock absorber. Below is some relevant information: 1. Definition of Shock Absorber: The car shock absorber (including the shock spring) is the most important component in the vehicle's vibration filtering system. 2. Function of Shock Absorber: It absorbs vibrations and impacts caused by uneven road surfaces during driving, thereby providing a comfortable ride for passengers. 3. Hazards of Damaged Shock Absorber: Once the shock absorber is damaged, the vehicle may experience excessive bumpiness and instability while driving, which can severely impact driving safety in serious cases. 4. Common Damages to Shock Absorbers: (1) Abnormal Noise: If the shock absorber makes unusual noises when driving on bumpy roads, it is highly likely that the shock absorber is damaged. (2) Oil Leakage: By using a flashlight to inspect the shock absorber through the wheel arch, if oil leakage is observed on the exterior of the shock absorber, it indicates that the shock absorber is already damaged. (3) Loose Chassis: When driving on bumpy roads, if the vehicle's body exhibits excessive bumpiness and instability, it is often a sign that the shock absorber is malfunctioning.
