How to reduce noise from Bonnet Gas Struts?

- Jul 18, 2025-

As a trusted supplier of Bonnet Gas Struts, I understand the frustration that excessive noise from these components can cause. Whether you're an automotive enthusiast, a mechanic, or a professional in the automotive industry, dealing with noisy Bonnet Gas Struts can be a real headache. In this blog post, I'll share some effective strategies to reduce noise from Bonnet Gas Struts based on my years of experience in the field.

Understanding the Causes of Noise in Bonnet Gas Struts

Before we dive into the solutions, it's important to understand what causes the noise in Bonnet Gas Struts. There are several factors that can contribute to this issue:

  1. Lack of Lubrication: Over time, the moving parts of the gas struts can dry out, leading to increased friction and noise. This is especially common in older vehicles or in struts that have been exposed to harsh environmental conditions.
  2. Wear and Tear: Continuous use can cause the internal components of the gas struts to wear down. This can result in loose parts, which can rattle and make noise when the bonnet is opened or closed.
  3. Improper Installation: If the gas struts are not installed correctly, they may not function properly. This can lead to misalignment, which can cause the struts to rub against other parts of the vehicle and produce noise.
  4. Environmental Factors: Exposure to extreme temperatures, moisture, and dirt can also affect the performance of the gas struts. For example, cold temperatures can cause the gas inside the struts to contract, while moisture can lead to corrosion.

Strategies to Reduce Noise from Bonnet Gas Struts

Now that we understand the causes of noise in Bonnet Gas Struts, let's explore some effective strategies to reduce it:

1. Lubrication

Lubrication is one of the simplest and most effective ways to reduce noise from Bonnet Gas Struts. By applying a high - quality lubricant to the moving parts of the struts, you can reduce friction and prevent the parts from rubbing against each other.

  • Choose the Right Lubricant: Look for a lubricant that is specifically designed for automotive applications. Silicone - based lubricants are a popular choice as they are resistant to water and can withstand a wide range of temperatures.
  • Apply the Lubricant Properly: First, clean the struts with a mild detergent and water to remove any dirt or debris. Then, apply the lubricant to the piston rod and the mounting points of the struts. Make sure to spread the lubricant evenly and wipe off any excess.

2. Inspect and Replace Worn Parts

Regular inspection of the Bonnet Gas Struts is essential to identify any worn or damaged parts. If you notice any signs of wear, such as cracks, leaks, or loose components, it's important to replace the affected parts as soon as possible.

  • Check the Piston Rod: The piston rod is one of the most critical parts of the gas strut. Look for any signs of scratches, dents, or corrosion on the rod. If the rod is damaged, it can cause the strut to malfunction and produce noise.
  • Inspect the Seals: The seals in the gas struts prevent the gas from leaking out. Over time, these seals can wear out, leading to a loss of pressure and noise. If you notice any signs of leakage around the seals, replace them immediately.

3. Ensure Proper Installation

Proper installation is crucial for the smooth operation of Bonnet Gas Struts. If the struts are not installed correctly, they can cause noise and other problems.

  • Follow the Manufacturer's Instructions: Always refer to the manufacturer's installation instructions when installing the gas struts. Make sure to use the correct tools and follow the recommended torque settings.
  • Check the Alignment: Ensure that the gas struts are properly aligned with the bonnet and the mounting points on the vehicle. Misalignment can cause the struts to rub against other parts and produce noise.

4. Protect the Gas Struts from the Environment

Taking steps to protect the Bonnet Gas Struts from environmental factors can help extend their lifespan and reduce noise.

  • Keep the Struts Clean: Regularly clean the gas struts to remove any dirt, dust, or debris. This can prevent the build - up of contaminants that can cause wear and noise.
  • Use Protective Covers: Consider using protective covers for the gas struts. These covers can shield the struts from moisture, dirt, and UV rays, which can all contribute to damage and noise.

Other Applications of Gas Springs

Gas springs are not only used in Bonnet Gas Struts but also in various other applications. Here are some examples:

  • Gas Spring for Car: Gas springs are widely used in cars for applications such as trunk lids, hatchbacks, and engine hoods. They provide smooth and controlled movement, making it easier to open and close these components.
  • Gas Spring for Tanning Bed: In tanning beds, gas springs are used to adjust the angle of the bed. They offer a convenient and reliable way to position the bed for optimal tanning.
  • Murphy Bed Gas Spring: Murphy beds, also known as wall beds, use gas springs to assist in the lifting and lowering of the bed. This makes it easier to convert the bed from a vertical to a horizontal position.

Conclusion

Reducing noise from Bonnet Gas Struts is a manageable task if you understand the causes and take the appropriate steps. By lubricating the struts, inspecting and replacing worn parts, ensuring proper installation, and protecting the struts from the environment, you can significantly reduce noise and improve the performance of your Bonnet Gas Struts.
