Coilovers squeaking over bumps can be troubleshooted and fixed using a variety of methods. Coilovers are a popular suspension upgrade for many car enthusiasts.
They offer improved handling and adjustability compared to stock suspension systems. However, coilovers can sometimes develop a squeaking noise when going over bumps. This can be quite annoying and can also indicate an underlying issue with the suspension system. In this guide, we will explore some common causes of coilover squeaking and provide troubleshooting tips and fixes to help you resolve the issue.
By following these steps, you can enjoy a smoother and quieter ride with your coilovers. So, let’s dive in and get your suspension system back in top shape.
Understanding Coilovers
When it comes to optimizing your vehicle’s suspension for enhanced performance and handling, coilovers are often the go-to choice for auto enthusiasts. However, despite their numerous advantages, coilovers can sometimes develop a bothersome issue – squeaking over bumps. In this troubleshooting guide, we will explore what coilovers are, how they work, and provide some helpful fixes to address the squeaking problem.
What Are Coilovers?
Coilovers, short for “coil over shock absorbers,” are a type of suspension upgrade that combines a coil spring and shock absorber into a single unit. They offer a higher level of adjustability compared to conventional shocks and springs, allowing enthusiasts to fine-tune their suspension to meet specific performance needs. Coilovers are commonly used in racing applications, as they provide improved cornering ability, reduced body roll, and better overall stability.
How Do Coilovers Work?
Coilovers work by utilizing a coil spring to support the weight of the vehicle and a shock absorber to dampen vibrations and impacts from the road. The coil spring, which is often adjustable, allows the suspension height to be modified, while the shock absorber controls the movement of the spring. When the vehicle encounters bumps or uneven road surfaces, the coilovers compress and extend to absorb the impact and maintain tire contact with the road, providing a smoother and more controlled ride.
Coilovers are designed to offer a range of adjustability, including compression and rebound damping settings. Compression damping refers to the resistance against the compression of the coil spring, while rebound damping is the resistance against the extension of the spring. These adjustments help fine-tune the suspension’s response to different road conditions and driver preferences, ensuring optimal performance and comfort.

If your coilovers are squeaking over bumps, it is often an indication of an underlying issue that needs to be addressed. Here are some common causes and fixes:
- Loose or worn-out components: Inspect the coilovers for any loose or worn-out components, such as top mounts, bushings, or locking collars. Tighten or replace these components as necessary.
- Lack of lubrication: Apply appropriate lubrication to relevant parts, such as the shock absorber shaft and spring perch, to reduce friction and eliminate squeaking.
- Dirt and debris: Clean the coilovers regularly to remove any dirt or debris that may contribute to the squeaking. Ensure that the coilovers are free from any contaminants that could cause friction.
- Inadequate preload or spring tension: Adjust the preload or spring tension according to the manufacturer’s recommendations to ensure proper load distribution and prevent excessive movement that can lead to squeaking.
By addressing these potential causes and performing the necessary fixes, you can resolve the squeaking issue and continue to enjoy the benefits of your coilovers. However, if the problem persists or you are unsure about performing the troubleshooting yourself, it is always recommended to consult a professional mechanic or suspension specialist for further assistance.
Identifying The Source Of The Squeak
If you’ve been noticing an annoying squeaking noise when driving over bumps, it’s important to identify the source of the squeak before determining the cause and finding a solution. The first step is to pinpoint where the squeak is coming from. It could be the front or rear of the vehicle, left or right side, or from under the hood.
Determining The Cause Of The Squeak
Once the source of the squeak is identified, the next step is determining the cause. Common causes of coilover squeaks include worn-out or dry bushings, loose components, inadequate lubrication, or damaged shock absorbers. It’s essential to carefully inspect the coilovers and related components to pinpoint the exact cause of the squeak.
Fixes And Maintenance
If you’re experiencing coilovers squeaking over bumps, this troubleshooting guide offers helpful fixes and maintenance tips to resolve the issue. Discover the potential causes and solutions to eliminate the annoying noise and improve your driving experience.
Lubricating The Coilover Components
One common cause of coilover squeaking is the lack of proper lubrication on the components. Regular lubrication is crucial in preventing the coilovers from squeaking over bumps. Ensure that you use a high-quality silicone-based lubricant or grease that is compatible with the materials used in the coilovers.
Replacing Worn-out Parts
Over time, the components of coilovers can wear out, leading to squeaking. Regular inspection of the coilovers is important to identify any worn-out parts. If you notice any signs of wear, such as tear or deformation, it is essential to replace the affected components promptly.
Adjusting Damping And Preload Settings
Improper damping and preload settings can also be a cause of coilover squeaking. Carefully adjust the damping settings according to the manufacturer’s recommendations to ensure optimal performance and reduced noise. Similarly, adjusting the preload settings can help alleviate any squeaking issues over bumps.
