Suspension Spring Symptoms, Function & Replacement Cost

Suspension springs are sometimes referred to as coil springs or coil-overs. The springs play an important role in ensuring a smooth and comfortable ride. That’s why they absorb all the stress and tension of a bump and make sure you don’t feel a thing. Suspension springs are made of industrial steel because they share the weight of the car with the suspension struts.

The springs are extremely durable, but anything can happen with mechanical equipment. The spring can snap in two or simply wear out due to excessive stress. If one of the springs is damaged, you usually have to replace the spring on the other side as well, because adding a new spring can affect the ride height.

If you do not replace both springs at the same time, your vehicle will look unstable and unbalanced. Repairing or replacing suspension springs requires precision and appropriate tools, so this is not normally a job to do at home yourself (unless you have the tools and knowledge). Therefore, a professional mechanic should be your first choice if you feel that something is wrong with your suspension.

Bad Suspension Spring Symptoms

Take a look at the symptoms below to know exactly when to go to the mechanic for a checkup.

Slight Tremors

The suspension springs act as cushions between the joints and the struts. The spring ensures that the struts do not feel the full force when going over a bump in the road. So if the spring breaks or is too worn out, you will feel a lot of shocks on your ride. Be very careful, because a broken spring can directly damage your struts and cause you even more headaches. If you think you might have suspension problems, it is best to test your vehicle on a familiar road and go over some bumps and potholes. If you feel the ride is bumpier than normal, it is time to see the mechanic.

Unbalanced Vehicle

The reason for replacing both suspension springs in the event of a defect is that if you do not replace both, your car will tip to the side. If your car is higher on one side and lower on the other, you may have a broken spring. Take your car to the mechanic as soon as this occurs.

Bouncy Ride

The suspension springs further absorb the force felt by the shock absorber. In other words, the shocks have a limit on the force they can absorb; the rest is transferred upwards to the spring. It is the task of the spring to become the last cushion for the shock absorbers. If the springs fail and/or the shocks become defective, the struts can break from brute force. So if you feel the unnecessary bounce in your car after going over a bump, make an appointment with a certified mechanic.

Uneven Wear of Tires

Any damage to the suspension means that your wheel alignment is affected. And if the wheels are not aligned correctly, the tires will take all the damage. That’s why you should regularly check your tires for wear and tear. If anything is unusual, such as uneven tread depth or irregular wear, your suspension is likely broken, and you need to see a mechanic.

The Tires Will Bounce Off the Road

If the suspension spring is crooked, the tires have a hard time staying on the road. After every bump, they can bounce up and never return to their original position. In this case, your car can fall down hard and many important components can be damaged. First of all, the suspension struts will feel the damage, then the underbody, and then other important engine parts. Not to mention that your own head will start spinning. To avoid further damage to your vehicle, you should therefore see a mechanic as quickly as possible.

Solutions

A part made of steel cannot be repaired at home. You definitely need the help of a certified mechanic with the right tools to help you out of this mess.

Drive with Care

Drive carefully and try to avoid bumps and potholes, especially at high speeds. This will ensure that the suspension of your car and other parts stay in place and have a long life. Otherwise, one big bump can cause everything that is not yet broken to break. While this is not the best solution, it can help you stay away from the mechanic until you save money for a real solution, i.e. replacing the suspension springs.

Make sure you choose the right model for your car. The springs may also differ between car models, depending on whether you have a sports suspension or not.

Suspension Spring Replacement Cost

The only solution for a bad suspension spring is to either replace it or repair it, both of which are quite difficult to do yourself. So you will most likely have to visit the mechanic and spend money. The sooner you go to the mechanic after you have seen one of the signs mentioned above, the less money you will spend. If you delay a visit to the mechanic, you will only have more problems in the future.

Suspension coils are made of steel, so as you can imagine, they will not be cheap. Indeed, new suspension springs can cost you a fortune. Of course, the make and model of your car is the deciding factor when it comes to price, but even then, buying a coil spring will not spare your wallet. So the first thing you should do is look to repair the existing coil.

However, a repair is only possible if your coil spring is intact and only worn out.

However, if it comes to the point where you need to replace the entire suspension coil, you will be faced with a repair cost of $100 to $400. This price also depends on the availability of the part. For example, the rollover coil on a Porsche will cost you more than the spring on a Dodge. This does not include the labor cost: you will have to pay an additional $100 to $200 for this as well.
