Suspension 101: understanding your car’s suspension system

As you drive down the road, your car’s suspension system works hard to keep your ride smooth and stable. The suspension system is a complex network of components that work together to absorb shock, maintain traction and provide stability when driving. By keeping an eye out for signs of wear or damage and working with a trusted mechanic, you can ensure that your suspension system is always in top condition, providing a smooth and stable ride wherever you go.

Springs – the most visible part of the suspension system

Springs are a critical component of a vehicle’s suspension system as they absorb the shocks and vibrations that occur while driving on uneven roads. They help maintain the tyre-to-road contact, ensuring a smooth and comfortable ride for passengers. In addition, they protect the vehicle’s chassis from damage caused by the impact of bumps and potholes. Properly functioning springs also help improve vehicle handling, stability and braking performance. Without springs, a vehicle’s suspension system would not be able to function and the ride quality would be severely compromised.

Shock absorbers

Shock absorbers are a crucial component of a vehicle’s suspension system. They are responsible for damping the oscillations and vibrations caused by the movement of the vehicle. Without shock absorbers, the suspension system would be unable to control the up-and-down motion of the wheels, resulting in an uncomfortable ride and poor handling. Furthermore, shock absorbers help to maintain tyre contact with the road which is essential for vehicle stability and control.


Struts play an important role in a vehicle’s suspension system. They are designed to absorb shock and vibration while providing structural support to the vehicle’s body. Struts also help maintain proper wheel alignment and handling which improves overall safety and stability while driving. Without properly functioning struts, a vehicle may experience excessive bouncing, poor handling and increased wear and tear on other suspension components. Regular maintenance and replacement of worn-out struts are important for optimal performance and safety on the road.

Sway bars
Sway bars, also known as anti-roll bars, connect the left and right wheels of a vehicle and help to reduce body roll during cornering. They accomplish this by transferring some of the weight from the outer wheels to the inner wheels, which helps to keep the vehicle level and improve traction.

Control arms

Control arms are responsible for connecting the suspension to the vehicle’s frame. They help to control the movement of the wheels by limiting their range of motion and providing stability during acceleration, braking and cornering. Without properly functioning control arms, a vehicle’s handling and ride quality can suffer, leading to safety concerns and discomfort for the passengers.

Signs that your suspension may need repair or replacement

Signs that your suspension system may need repair or replacement can include uneven tyre wear, excessive bouncing or swaying, pulling to one side when driving, and a noticeable increase in vibration or noise while driving. If you notice any of these symptoms, it is essential to have your suspension system inspected by a professional mechanic as soon as possible.
