A coil spring is an essential component of your car's suspension system, responsible for absorbing shocks and maintaining the correct ride height. In this blog, we will discuss the factors that affect coil spring replacement costs and provide tips on how to save money on this essential maintenance task.

What does a coil spring do?

A coil spring works by compressing and expanding to absorb the impact from the road, providing a smooth and comfortable ride for passengers. It also helps maintain proper wheel alignment and tyre contact with the road surface, which is crucial for safe and efficient driving.

Properly functioning coil springs are essential for optimal handling, braking, and acceleration, so knowing what to look out for is crucial for your and your family's safety.

What causes a car coil spring to break?

Coil springs are a common component of a car's suspension system, providing support and stability for the vehicle. However, there are several reasons why these essential parts might break or fail over time. One major cause is age and wear. As the coil spring is constantly compressed and expanded during normal driving conditions, it can experience metal fatigue that eventually leads to a break.

Another factor that can contribute to coil spring failure is corrosion. When exposed to moisture, salt, and other corrosive elements on the roadways, the metal in the coil spring may weaken over time. This makes it more prone to breaking when subjected to sudden stresses or impacts from potholes or other hazards on the road.

Speaking of impact damage, this is another common reason why coil springs might break unexpectedly. A strong jolt from hitting a pothole or running over debris in the road can put sudden and excessive force on the spring. This can result in significant damage or even complete failure of one or more coils within the spring.

And, last but not least, although rare, manufacturing defects may also lead to premature failure of a car's coil springs. Poorly made products can have weak spots that aren't immediately apparent but could worsen as they're used under typical driving conditions.

Signs of a failing coil spring

Common symptoms indicating that a coil spring might need a replacement include:

• Unusual noises coming from the suspension system, such as clunking or squeaking
• Uneven tyre wear due to improper wheel alignment
• Sagging or uneven ride height
• Reduced handling capabilities, such as excessive body roll or a bouncy ride

To inspect your coil springs for damage or wear, you can visually check for cracks, corrosion, or deformation. However, diagnosing a failing coil spring can be challenging, so it's best to consult a professional mechanic for further assessment if you suspect a problem.

How much does it cost to replace a coil spring?

The average cost of a coil spring replacement in the UK is between £180 to £300. Normally a front coil spring replacement cost is around £220, while it's a little cheaper at £180 for the rear coil springs.

Dealership service centres tend to charge more for parts and labour than independent garages, so it's worth shopping around to find the best price. However, it's essential to consider factors such as warranty coverage, customer reviews, and technician expertise when choosing where to have your coil spring replaced.

Factors affecting coil spring replacement cost

When it comes to replacing a coil spring in your vehicle, there are several factors that can impact the overall cost of the job. One key factor is the make and model of your car. Some vehicles may require more expensive or specialised parts, which can drive up the cost of replacement.

Another important consideration is the material and quality of the replacement coil springs you choose. Higher-quality and performance-oriented options will generally be more expensive than standard replacements. However, investing in better-quality springs could lead to improved handling and a longer lifespan for your suspension system.

Labour costs also play a significant role in determining the total price tag for this type of repair. The complexity of the job and the hourly rate charged by mechanics can greatly affect labour costs.

In addition to these factors, other repairs or replacements may be needed alongside replacing a worn-out coil spring. For instance, if other suspension components are found to be damaged or nearing failure during the inspection, they may need repair or replacement at the same time as the coil spring. This additional work can further increase the overall costs associated with repairing your vehicle's suspension system.

Can you drive with a broken coil spring?

Driving with a broken coil spring is not recommended, as it can compromise your vehicle's handling, braking, and overall safety. A broken spring can also cause damage to other suspension components or your tyres, leading to more expensive repairs down the line.

Is a coil spring an MOT failure?

Yes, a broken or significantly damaged coil spring is considered an MOT failure in the UK. It is essential to address any coil spring issues before your vehicle's MOT test to ensure it passes and remains roadworthy.

How to save money on coil spring replacement

Coil spring replacement can be an expensive and time-consuming task, but there are ways to save money without sacrificing the quality or safety of your vehicle. One option is to source affordable replacement parts from reputable aftermarket manufacturers. However, it's important to be cautious of low-quality parts that could compromise your vehicle's performance and safety.

Another way to save money on coil spring replacement is by considering DIY replacement versus professional service. If you have the necessary skills, tools, and confidence, you might consider replacing the coil spring yourself. This can potentially save you hundreds of dollars in labour costs alone. However, it's crucial to weigh the risks and benefits carefully before attempting this complex and potentially dangerous task.

Regular maintenance is another key factor in prolonging the life of your coil springs and reducing overall costs. Your suspension system should be well-maintained with regular visual inspections, proper wheel alignment, and addressing any issues promptly. This proactive approach can help prevent major repairs down the road while keeping your car running smoothly.
