What are the signs of a broken car shock absorber?

[DiPresley]

When a car's shock absorber is damaged, there are usually signs such as body shaking and abnormal heat. Below is a detailed explanation of these symptoms: Body Shaking: For sedans, shaking the car body can help determine the performance of the shock absorber. Alternatively, you can observe the vehicle's rocking state after emergency braking. If the shock absorber fails, the car will rock significantly more times than under normal conditions. When the vehicle is stationary, forcefully hold the bumper or hood and shake it. When the shaking reaches its maximum amplitude, suddenly release your grip. Abnormal Temperature: The shock absorber converts the mechanical energy of wheel and body vibration into heat, which is then dissipated, thereby reducing vibration. The more vibration energy it absorbs, the higher the temperature of the shock absorber. When the shock absorber's energy absorption reaches saturation, the temperature basically stops rising. Typically, it takes about half an hour to reach a thermal equilibrium state.
