When you drive over a bump in the road, you likely expect a smooth, controlled motion rather than a jarring crash. That comfortable ride is largely thanks to your car’s suspension system, and a key player in that system is the strut. While many people have heard of them, it’s common to wonder exactly what do struts do on a car and why they are so important for your daily drive.
What do struts do on a car?
A strut is a major structural part of your vehicle’s suspension. Think of it as a shock absorber that’s been built into a coil spring. This single unit serves two critical purposes. First, it dampens the bounce caused by hitting bumps and imperfections in the road, just like a standard shock absorber. Second, because it’s so robust and connected directly to the steering knuckle, it provides structural support for the vehicle’s suspension, helping to maintain proper wheel alignment and giving your car its shape and stance.
How you benefit from healthy struts
When your struts are in good condition, you enjoy a safer and more comfortable driving experience. They keep your car’s tires firmly planted on the pavement, which provides better traction and shorter stopping distances, especially during emergency braking. You’ll also notice more precise steering control and less body roll when going around corners. Essentially, they are a vital safety component that works tirelessly to maintain contact between your car and the road.
Signs your struts might need attention
Like any car part, struts wear out over time. Being aware of the symptoms can save you from bigger problems down the road. Listen for a knocking or clunking sound when driving over bumps, which could indicate a worn strut mount. Pay attention if your car nose-dives forward when you brake hard or leans excessively in corners. You might also notice an unusually bouncy ride or that your car continues to bounce several times after going over a bump. Uneven tire wear can also be a telltale sign of failing struts.
Caring for your car’s suspension
While struts don’t require regular maintenance like an oil change, it’s wise to have them inspected by a trusted mechanic during routine service visits. They can check for physical damage, such as fluid leaks from the shock absorber component, and assess their overall condition. Replacing struts in pairs (both front or both rear) is highly recommended to maintain balanced handling and safety.
Your car’s struts are fundamental to a smooth, stable, and safe ride. By understanding their role and recognizing the signs of wear, you can ensure your vehicle continues to handle the road with confidence and comfort for years to come.
