A crucial component of your car’s suspension is the coil spring. Each wheel has these, and they cushion impacts to make sure your ride is comfortable. The impact of driving over difficult terrain is supposed to be absorbed by coil suspension springs, which also aid in maintaining the proper height for your car.

But a number of things, particularly in the winter, can cause your coil springs to break, posing a serious risk to the safety of both drivers and passengers. Thus, in this article, we’ll be discussing the symptoms of a broken coil spring.

Symptoms of a broken coil spring

So, let’s dive in!


Symptoms of a broken coil spring

The car sags in the place where a coil spring fails or breaks. Additionally, the ride will be less enjoyable as you travel because of the increased bounce. Uneven tire wear, unusual noises, especially when turning, and a distinct rattling sound are all symptoms of bad coil springs.

Strange noises

Investigate any strange noises you notice while driving as soon as you can. On uneven surfaces, you’ll hear a clunking or knocking sound if your coil springs are slowly corroding.

Extreme swinging

This frequently occurs when you have unbalanced wheels or uneven tires. Your suspension’s components will collide with one another, changing the angles of travel. This may cause your automobile to bounce excessively, steer unevenly, or wobble more than usual.

irregular wheel arches

Looking at your car’s corners is another way to determine if the coil springs have deteriorated. Get a tape measure and measure the distance between your wheel arches and the ground if one corner appears to be lower than the rest. If the discrepancy is significant, a coil spring may be damaged.

Increased braking distance

The friction between the tires and the road decreases as your coil springs corrode. This results in longer stopping distances, especially in ice conditions, and poses a serious risk to you, other drivers, and pedestrians.

What causes the spring coil to break

Coating damage and corrosion

A flexible plastic coating is applied to coil springs to assist in preventing corrosion of the metal. But over time, due to continuous compression and being struck by road stones, this coating may become harmed, allowing rust to develop on the coil. When this occurs, the coil may become fragile and even shatter. Regularly driving in tough terrain will increase the likelihood of a break.

Blown tires

Uneven wear on your suspension from unbalanced wheels could result in a broken coil. Meanwhile, a flat or blown tire can put a lot of strain on your suspension system and perhaps damage a coil. Your steering and braking systems may be harmed by a broken coil spring.

Fluid leaks in struts

When a strut, which typically consists of a shock absorber and a spring, leaks hydraulic fluid, it loses its ability to function, which puts greater strain on the neighboring coil and raises the risk of a break.

If your vehicle makes more noise when you drive over dips and bumps, you may have a hydraulic fluid leak. Reduced hydraulic pressure may result in springs making contact with other suspension parts, harming brake lines or even the exhaust system.

How to prevent coil spring corroding

Never overburden your vehicle

Avoiding overloading your vehicle not only helps you use less fuel but also keeps your coil springs from corroding over time and breaking.

Maintaining excellent tire condition

Regular tire maintenance and inspections will prevent your coil springs from experiencing excessive pressure. By doing this, you can keep them in good shape and stop them from cracking.

Be cautious when navigating potholes and bumps

Your coil springs are put under stress when you drive recklessly on bad roads or into potholes; the more carefully you drive, the longer your coil springs will endure.

Clean the vehicle’s underneath

Regularly clearing out any accumulated grit, dirt, or ice underneath your car during the winter, whether with a hosepipe or a pressure washer, keeps your coil springs in top shape.

It makes a huge difference to understand the factors that lead to coil spring failure and how to stop them from corroding. Our step-by-step instruction explains how to prevent the paint flaw from corroding and turning rusty if you’ve discovered a spot that needs to be touched up.

How Much Does It Cost to Replace a Coil Spring?

Typically, coil springs only cost $55 to $150 per piece. But if you replace all four, the cost quickly rises to between $220 and $600. If you are unable to repair the coil springs yourself, you must hire a mechanic, who will likely charge an additional $350 to $800 for a full replacement.

This cost may be reduced if you only want to replace the front or back pairs of springs. However, you could also need to include other services, such as shock replacement.

Can you drive with a broken coil spring?

No, you shouldn’t drive while your coil spring is broken. It needs to be fixed as soon as you can. Some motorists might choose to continue on a damaged spring coil in order to get to a garage or a house. Driving with a broken coil spring, however, will probably result in a rough ride and make it harder to control the vehicle in an emergency.

If you drive the automobile with a damaged coil suspension spring, it will put additional strain on the nearby shock absorber and could result in significant damage.

How serious is a broken coil spring?

If one of the coil springs in your car breaks, the lowest corner of the car will be over the damaged spring coil. Because of the unequal pressure on the tires caused by a broken coil spring, the damaged tire will wear down more quickly on one side. And if the coil comes loose from the car, it certainly poses a risk to other drivers.

What happens when a coil spring breaks?

If one of the coil springs in your car breaks, the lowest corner of the car will be over the damaged spring coil. Because of the unequal pressure on the tires caused by a broken coil spring, the damaged tire will wear down more quickly on one side.

What does a broken coil spring sound like?

The back of the car may appear to sit lower than the front since the rear springs often brake first. the noise of knocking over bumps. The suspension angles and travel are altered by a damaged coil spring, which can produce rattle or clunking noises.

Can a broken coil spring cause vibration?

Your car will probably bounce more when you’re driving if a coil spring is broken. If a car jumps a lot, especially when traveling over speed bumps, you can tell if the coil spring is broken since damaged coil springs will make your car bounce a lot.

How do you tell if your shocks or springs are bad?

What causes spring failure?

The most frequent reasons for spring failures include poor design, poor materials, poor processing, and unique operating circumstances. The majority of the time, these causes lead to failure from tiredness.

Can I replace just one coil spring?

To maintain performance and safety, keep in mind that one spring should never be changed on its own. Instead, automobile owners should have the front or rear set changed as a pair. The suspension system and coil springs will be examined by the mechanic during replacement.

What does a broken spring look like?

Can you drive with a damaged coil spring?

You cannot operate a car with any suspension component broken, regardless matter whether it is a broken coil spring or shock absorber. This is due to the fact that driving with a damaged or collapsed coil spring might result in sagging, which could ultimately result in greater long-term harm to your car.

How do I know if a spring has gone on my car?

If your car sags or droops on one side or corner, that is the biggest indication that your coil springs need to be repaired. One side of the vehicle may have been frequently overloaded if there is drooping or sagging on one side. Additionally, your automobile might swing more during curves or bounce higher than usual.

Do new coil springs make a difference?

The ride and handling of a car can be significantly improved by replacing the coil springs. Choosing the proper coil spring is essential for obtaining improvements in performance or matching OE performance.

How do you reset a coil spring?

For full spring pack resets, a hot setting is advised since it helps to preserve the “memory” that the spring is set to. Prior to re-cambering, spring leaves are heated to a “black heat,” or temperatures between 350 and 400 degrees Celsius, and then let go “air cool,” which aids in maintaining the new height setting.
