First, check the springs and damping oil of the shock absorber for deterioration or wear, which may cause the shock absorber to make noise during operation.
Second, there may be problems with the installation of the shock absorber, such as poor mounting or incorrect mounting position, which may cause the shock absorber to rub or collide with other parts during movement.
In addition, if the dust cover of the shock absorber is broken, dust and dirt may enter the inside of the shock absorber, affecting its normal operation and generating noise.
