Coilover Clunking Over Bumps: Causes & Solutions
If you hear clunking noises from your car’s suspension when driving over bumps, it could be a problem with your coilovers. This often happens to drivers who upgrade their suspension for better performance but end up dealing with unexpected sounds. At Tech Savvy Automotive in Brantford, ON, we’re experts in finding and fixing these issues so your ride stays smooth, quiet, and reliable.
This comprehensive guide explains what coilovers are, why clunking might happen, and how we can help resolve the problem.
What Are Coilovers?
Coilovers are a type of suspension system that combines a coil spring and a shock absorber into a single unit. They are often used in performance vehicles because they provide several key benefits:
- Adjustable Ride Height: You can lower or raise your car to achieve the desired look or improve performance.
- Enhanced Handling: Coilovers improve vehicle stability and cornering.
- Durability: High-quality coilovers are built to last and handle the demands of spirited driving.
While coilovers are a popular upgrade for car enthusiasts, they are not without their challenges. Clunking over bumps is one of the most common complaints associated with coilovers.
Why Do Coilovers Clunk Over Bumps?
Clunking noises from your suspension can be annoying and concerning. Fortunately, they are usually the result of specific issues that can be diagnosed and resolved. Here are the most common reasons for coilover clunking:
1. Loose Bolts or Components
One of the simplest causes of clunking is loose hardware. Over time, bolts and nuts in your suspension system can loosen due to regular driving vibrations. If your coilovers or their mounting points aren’t tightened to the correct torque specifications, you may hear clunking noises when driving over bumps.
2. Improper Installation
Coilovers need to be installed with precision. If they are not mounted correctly or aligned properly, the misalignment can create noises during suspension movement. Installation errors, such as poorly secured top mounts or incorrectly adjusted preload, are common culprits of clunking.
3. Damaged or Worn Bushings
Bushings are rubber or polyurethane components that help cushion your suspension and reduce vibrations. If these bushings become worn, cracked, or damaged, they may fail to absorb the impact from bumps effectively, leading to clunking sounds.
4. Spring Binding
Spring binding happens when the coil spring on the coilover twists or catches instead of compressing smoothly. This issue can cause a clunking or popping sound as the spring moves. It is often caused by insufficient lubrication or misaligned components.
5. Incompatible Components
Your suspension system relies on all components working together seamlessly. If your coilovers are paired with incompatible parts, such as mismatched top mounts or spacers, this can create excessive movement or improper alignment, resulting in noise.
6. Low-Quality Coilovers
Not all coilovers are made equal. Budget coilovers may lack the durability and precision engineering required for quiet operation. Poorly designed components can result in noise, performance issues, and premature wear.
Diagnosing Coilover Clunking at Tech Savvy Automotive
At Tech Savvy Automotive in Brantford, ON, we take a systematic approach to diagnosing coilover clunking issues. Our team of expert technicians is trained to identify and resolve suspension problems efficiently. Here’s what we do:
Step 1: Visual Inspection
We start with a thorough visual inspection of your coilovers and surrounding suspension components. This includes checking for loose bolts, worn bushings, and any visible signs of damage.
Step 2: Road Test
To better understand the clunking noise, we take your vehicle for a test drive. This allows us to hear the sound firsthand and observe how the suspension behaves under real driving conditions.
Step 3: Component Testing
We examine each component of your suspension system, including the coilovers, mounts, and bushings. If we detect any worn or damaged parts, we’ll recommend the appropriate repairs or replacements.
Step 4: Suspension Alignment Check
Proper alignment is crucial for coilover performance. We ensure that your suspension system is correctly aligned to minimize unnecessary stress and movement.
Solutions to Coilover Clunking
Once we’ve identified the cause of the clunking noise, our team will recommend and implement the best solution. Here are some of the most common fixes:
1. Tightening Loose Components
If loose bolts or nuts are causing the noise, we’ll tighten them to the manufacturer’s specifications. A simple adjustment is often enough to resolve the issue.
2. Reinstalling Coilovers
If improper installation is the cause, we’ll realign and reinstall the coilovers. This includes correctly setting the preload, securing top mounts, and ensuring all parts are properly fastened.
3. Replacing Worn Bushings
Damaged or worn bushings can no longer cushion the suspension effectively. We replace these with high-quality components to restore quiet operation and improve durability.
4. Applying Spring Lubrication
To address spring binding, we use specialized lubricants to ensure the springs compress smoothly and quietly. This eliminates the popping or clunking sound associated with binding.
5. Upgrading Incompatible Parts
If your coilovers are paired with incompatible components, we’ll recommend replacements that are designed to work together. Using the right parts ensures optimal performance and reduces noise.
6. Replacing Low-Quality Coilovers
If the clunking noise is due to poor-quality coilovers, we can help you select and install a better set. Investing in high-quality coilovers reduces noise and improves ride comfort.
Preventing Coilover Clunking in the Future
