Inspection method of Toyota Corolla shock absorber:
Make the car stop after driving 10km on a road with poor road conditions and touch the shock absorber shell with your hands. If it is not hot enough, it means that there is no resistance inside the shock absorber and the shock absorber does not work. At this time, you can add appropriate lubricating oil, and then test, if the shell heats up, there is a lack of oil inside the shock absorber, and enough oil should be added, otherwise the shock absorber has failed. When the car is driving slowly and braking urgently, if the car vibrates violently, it indicates that there is a problem with the shock absorber.
