The abnormal sound of mazda 6 chassis may be caused by many reasons, such as the damage of the shock absorber, the rubber damage at the top of the shock absorber, the aging of rubber parts such as the lifting lug of the balance bar and the rubber sleeve of the arm. It is recommended to go to 4S shop or repair shop for on-site inspection.
