What Are Shock Absorbers?

Shock absorbers are a vital part of your suspension system, as they ensure your vehicle operates efficiently, safely, and smoothly – but how do shock absorbers work? In this guide we’ll take you through the specific role a shock absorber plays in a car’s suspension and define exactly how they operate.

What Do Shock Absorbers Do?

Simply put, shock absorbers are designed to absorb or dampen any impact pulses from the surface of the road. Shock absorbers are effective at reducing tyre wear, as well as improving stability, braking, and driver comfort.

The shock absorber is a fundamental component of the suspension system and helps keep you safe on different terrain. As a result, they can also prevent unwanted spring motion and keep you in control of the vehicle.

How Many Shock Absorbers Does a Car Have?

Overall, there are four shock absorbers fitted in a vehicle, with one located at each wheel. Fortunately, these shock absorbers don’t require special maintenance after a certain amount of time, as modern systems tend to be robust. Having said that, as with most components in a vehicle, they can gradually wear and fail over time.

How Shock Absorbers Work?

Shock absorbers work by utilising the kinetic energy created from your suspension and converting it into thermal energy. This heat is then dissipated via the heat exchange, which in turn allows the suspension to dampen the shock that’s created from a road’s surface.

How Long Do Shock Absorbers Last?

Usually, shock absorbers can last anywhere between 5 and 10 years. This all depends on how frequently you drive your vehicle, and the types of terrain you drive on. For example, trucks or SUVs may drive on a bumpy surface, and so will rely on their shock absorbers to mitigate the impact more than a car driven in the city. Unsure when it’s time for a replacement? Look out for these tell-tale signs:

• If your vehicle continues to bounce when you drive over a speed bump or pothole.

• The front end of your vehicle dips forward when you brake.

• Your vehicle tilts to one side, even when the vehicle is immobile.

• If you notice your car sometimes steers slightly to the left or right.

• There’s a leak coming from your shock absorbers. Do you notice any oil coming from the area where your suspension is located?

Notice something that isn’t quite right? Don’t worry, just make sure you get a second opinion from an expert who’ll be able to diagnose the problem for you. You’ll then know for certain if you need a replacement shock absorber or not.
