The suspension system in a vehicle is one of the most vital components of the vehicle today. Shock absorbers in suspension systems as you know them today were first introduces to cars in 1901, and have since become an indispensable part of all automotive. What exactly is the suspension system in cars? What is the system made of? And how can you ensure that your suspension system is working well? Read on to understand more about this essential car system.


What is a vehicle suspension system?

The chassis is the metal base of the car that is closest to the road. The rest of the components of the vehicle fit on the chassis and are held in place on this metal platform of sorts. A vehicle suspension system is connected to the chassis of the vehicle.

The suspension system performs the function of absorbing various levels of the impact caused by uneven road surfaces. By absorbing such impacts, the suspension system does not let the vehicle rattle and makes the ride smooth and comfortable for the people inside the car.


Main components of a car suspension system

Springs – There are different kinds of springs used in modern car suspension systems. Their main function is to absorb impact and keep it away from the body of the car and its passengers.

Shock absorbers – Shock absorbers are cylindrical in shape. The springs usually sit inside this cylinder. Most modern shock absorbers are oil based, which means that the springs are dipped in oil all the time. Shock absorbers help minimize oscillatory movement of the springs on impact since excessive oscillation can make you lose control of the vehicle to some extent.

Anti-sway bars or dampers – These are thick metal bars that help minimize swaying of the vehicle on uneven surfaces. They connect the two parts of the suspension system at the ends of the axle and help keep the vehicle level with the road. Less sway means more control for the driver over the vehicle and more comfortable ride for passengers.


Basic checks to ensure the health of your car suspension system

There are some basics signs that you need to watch out for when it comes to the suspension health of your car.

  • Excessive swaying or thudding of vehicle on uneven surfaces
  • Squeaking noises every time the suspension moves.
  • Height of the vehicle lowering without any changes made by you.
  • Oil leakages over the shock absorber cylinders.

If you notice any of these signs, it means that your car suspension system is either worn out or damaged. You should take it to your mechanic right away and the suspension fixed to ensure your vehicle does not get damaged and you continue to have a comfortable ride every time.

Even if you do not notice any visible signs of wear and tear or damage of your car suspension system, you should get your suspension system checked at least once a year or after 25,000 miles, and then after every 6,000 miles. Your mechanic may suggest a different timeline based on your specific usage and driving conditions.
