The coil spring suspension exists in the suspension system of your vehicle. A better name for a coil spring is a compression spring because they are meant to help absorb the shock inflicted upon the vehicle. Basically, the coil spring suspension will absorb the bumpiness and shakiness as you’re driving on the road. That way, your driving experience can feel a lot smoother and more comfortable because you won’t be bouncing up and down like you would if you didn’t have the coil spring suspension.
The coil spring suspension is under tremendous pressure because it holds all your vehicle’s weight. Meanwhile, it allows the wheels to stay vertically on the road after they drive over an object or obstacle. The upper part of the coil spring is positioned below the spring perch while the bottom part of the spring is positioned on the lower control arm. As you may know, the lower control arm assists in keeping the wheels securely held in place. Since the spring is above the lower control arm, it absorbs all the shock from down below. That way, the people inside the cabin above the coil spring can remain comfortable as they drive over obstacles on the road.
The Top 5 Symptoms
If you have a bad coil spring suspension in your car, there are definitely going to be some noticeable symptoms that you will experience. Once you recognize them for what they are, you should do something about them immediately.
Below are the top 5 symptoms of a bad coil spring suspension.
Sagging Corners – If you have a bad coil spring, that corner of the vehicle might sag more than the other corners. This will easily be noticeable simply by looking at it from the outside. But when you are driving the vehicle, you will have less stability from this sagging too. This problem will cause other symptoms to get worse, such as excessive tire wear and tear.
Bounciness – Coil springs are supposed to keep the vehicle from shaking and bouncing as it moves. But if you have bad coil springs in your vehicle, then it won’t be able to prevent this bounciness. This means that you will experience a lot of bouncing and shaking as you drive, especially if you drive over travel or rough road terrain.
Uneven Wear on Tires – Coil springs are supposed to keep the wheels and tires balanced on the road. This allows the tires to receive an equal amount of wear and tear as they’re moving on the road. However, if you have bad coil springs, then your tires will not be even on the road. Once that happens, the tire treads will get unevenly worn as well. This will cause problems as you’re driving on the road because there will be more shakiness and unsteadiness the faster you go.
Rattling – In addition to the shaking that you will experience from bad coil springs, there will be an annoying rattling noise coming from the suspension system too. This rattling noise will increase in volume as you accelerate the vehicle more and drive over rough roads. Do not just ignore this rattling noise because it is an early warning sign that you need to get your coil springs replaced.
Warning Light – Most newer vehicles have warning lights for the traction system of the vehicle. There are sensors built into the suspension which keep track of the vehicle’s stability. Whenever the sensors detect any unusual traction, it will cause the warning light to illuminate on the dashboard. Take this as a warning sign that you need to get your coil spring replaced immediately. You might not realize the exact problem at the time, but you will know soon enough if you experience the other symptoms too.
