Coil springs are an essential component of any vehicle's suspension. The springs are designed to absorb shocks, vibrations, and bumps as the vehicle travels over uneven roads and terrain. Coil springs can become damaged or worn out over time, and it is important to know how to tell if coil springs are bad so that you can replace them before they cause further damage to your vehicle. In this article, we'll discuss the signs and symptoms of worn-out or damaged coil springs and how to diagnose and replace them.
Signs and Symptoms of Bad Coil Springs
When a coil spring is damaged or worn out, you may notice certain signs and symptoms. These signs and symptoms can include:
- Uneven tire wear – If the coil springs are worn out, it can cause uneven tire wear as the vehicle is driven. This is because the coil springs are no longer able to absorb shocks and vibrations as they should.
- Rattling – If the coil springs are worn out, you may hear a rattling noise coming from the suspension when the vehicle is driven.
- Vibration – If the coil springs are worn out, you may feel a vibration in the steering wheel or seat when the vehicle is driven.
- Sagging – If the coil springs are worn out, the vehicle may appear to sit lower than usual as the springs are no longer able to support the weight of the vehicle properly.
- Leaking fluid – If the coil springs are worn out, they may leak fluid, which can cause fluid to build up in the suspension system.
How to Diagnose Bad Coil Springs
If you notice any of the signs and symptoms listed above, it is important to diagnose the issue as soon as possible. The most common way to diagnose bad coil springs is by performing a visual inspection. A visual inspection of the vehicle's suspension system can help you identify any signs of wear or damage. If you suspect that the coil springs are bad, it is important to have them inspected by a qualified mechanic as soon as possible.
In addition to a visual inspection, a qualified mechanic can also perform a pressure test to determine if the coil springs are bad. During a pressure test, the mechanic will use an air pressure gauge to measure the amount of pressure in the coil spring. If the pressure is too low, it could indicate that the spring is worn out or damaged.
How to Replace Bad Coil Springs
If you have determined that the coil springs are bad, it is important to have them replaced as soon as possible. The best way to replace bad coil springs is to have a qualified mechanic replace them for you. A qualified mechanic will be able to replace the coil springs correctly and safely, ensuring that your vehicle is safe to drive.
When replacing the coil springs, the mechanic will first remove the old springs from the vehicle. After the old springs are removed, the mechanic will install the new springs in the same position as the old ones. Finally, the mechanic will inspect the suspension system for any other signs of wear or damage that may need to be addressed.

What is a coil spring made of?
Most coil springs are made of steel or iron. Some coil springs may also be made of aluminum or other metals.
How long do coil springs last?
Coil springs typically last anywhere from 50,000 to 100,000 miles. However, this can vary depending on the type of vehicle and how it is driven.
What is the purpose of coil springs?
The purpose of coil springs is to absorb shocks, vibrations, and bumps as the vehicle travels over uneven roads and terrain. This helps to improve the ride quality and reduce wear and tear on the vehicle.
Do coil springs need to be replaced in pairs?
Yes, it is recommended that coil springs be replaced in pairs. If one spring is worn out or damaged, it is likely that the other one is as well.
What is the difference between coil springs and leaf springs?
Coil springs are typically made of a single piece of metal which is wound into a spiral shape. Leaf springs are made up of several layers of metal which are held together with metal clamps.
How much does it cost to replace coil springs?
The cost to replace coil springs can vary depending on the type of vehicle and the amount of labor required. On average, it can cost anywhere from $200 to $600 to replace both coil springs.
