“Good Shock Vs Bad Shock” – Why You Should Check Your Shock Absorbers!

Shock absorber’s purpose and design is to help keep the tires on the ground on bumpy roads so that you, as the driver, can maintain control of the vehicle. They consist of a cylinder called the reserve tube that is filled with hydraulic fluid, another tube called the pressure cylinder within that cylinder, a piston that travels through the inner cylinder, and valving that meters the flow of fluid from one side of the piston to the other as bumps in the road are encountered.

Several warning signs can tell you when shock absorbers need replacing, such as your car bottoms out over railroad tracks, speed bumps or dips in the road or keeps bouncing well after the fact.

Other signs are unusual noises over bumps, excessive body lean in turns or that the front end of the car dives sharply in hard braking. Because shocks wear out gradually, you might get used to a looser, bouncier ride, much like you get used to longer stopping distances as brake pads wear out.


One way to test shocks is to push down hard on each corner of a vehicle. If the car continues to bounce after you let go, your shocks need replacing. However, this test may require quite a bit of strength, and with many high-riding SUVs and pickups it isn’t easy to get the leverage you need.

These absorbers control the spring movement to maximize tire contact with the road. The car with worn shock absorbers seems to be shaking vigorously and the people inside are having a rough ride.Remember to check your shocks every 20 000 km. ITs recommended to replacement them every 80 000km.
