Gas struts are an essential component in many everyday items, from your car’s boot to office chairs and even heavy machinery. When they begin to wear out, they can cause inconvenience or even pose safety risks. So, can you replace a gas strut yourself, or should you call a professional? In this blog, we’ll walk you through what gas struts are, how to know when they need replacing, and whether you can handle the task on your own.
Understanding Gas Struts
A gas strut is a hydraulic or pneumatic device that uses pressurised gas to provide controlled force for lifting, supporting, or damping motion. They’re commonly found in car boot lids, hatches, office furniture (like adjustable chairs or desks), and even industrial applications. Gas struts help make lifting easier and smoother, preventing sudden or harsh movements.
Over time, these struts can lose their effectiveness or begin to fail, and it’s important to replace them before they stop working altogether. Some common signs your gas strut may need replacing include:
- Loss of lifting power (the hatch or lid no longer stays open or rises smoothly)
- Visible damage or wear (dents, cracks, or tears in the strut)
- Leaks (gas leaking from the strut)
- Unusual noises (creaking, popping, or grinding sounds during operation)
Assessing Whether You Can Replace It Yourself
Replacing a gas strut is something you can do yourself, but it depends on the application and your comfort level with DIY projects. Before diving in, here’s a checklist to assess whether it’s a task you can tackle:
Tools and Equipment You’ll Need:
- Wrench or socket set
- Safety gloves and goggles
- Replacement gas strut
- Screwdriver or other hand tools (depending on the mounting system)
- Support for the object being lifted (if applicable)
Difficulty Level:
For most household applications like a car boot or office chair, replacing a gas strut is a straightforward task. However, it’s crucial to understand the mounting system and the type of strut you’re working with. For more complex systems or larger machinery, you might need a professional’s help.
Safety Considerations:
- Wear protective gear (gloves and safety glasses) when handling gas struts, as they are under high pressure.
- Ensure proper support for heavy lids, boots, or panels when removing or installing the strut. A second pair of hands can be helpful for larger objects.
Pros and Cons of DIY Replacement:
- Pros:
- Cost savings, as you won’t have to pay for professional installation.
- It’s a manageable task for small and simple applications like a car boot or office furniture.
- Cons:
- Potential risk if the gas strut is improperly installed or the system is complex.
- Limited tools or knowledge can make the process harder than expected.
Step-by-Step Guide to Replacing a Gas Strut
If you feel confident and have the necessary tools, here’s a simple guide to replacing a gas strut:
Step 1: Prepare the Area and Gather Your Tools
Start by clearing the work area. Gather all your tools and the replacement strut. Make sure you have adequate lighting and a comfortable working space.
Step 2: Identify the Gas Strut and Its Mounting Points
Locate the gas strut and examine how it is mounted. Most gas struts are attached with ball joints or bolts. Take note of how the strut is positioned so you can install the new one in the same way.
Step 3: Remove the Old Gas Strut
Using the appropriate tools, carefully detach the gas strut from its mounting points. You may need to use a wrench or screwdriver to loosen bolts or remove clips. Always ensure the object being supported (e.g., a car boot) is securely held while you do this.
Step 4: Install the New Gas Strut
Position the new gas strut into place and attach it securely to the mounting points. Double-check that it is properly aligned and fastened. Be sure to follow any specific instructions from the manufacturer of the replacement strut.
Step 5: Test the New Strut
Once the new strut is installed, carefully test the object it supports (e.g., the car boot, lid, or chair). Ensure it opens and closes smoothly and stays in place when needed.
Common Pitfalls to Avoid
While replacing a gas strut is a manageable task, here are a few common mistakes to avoid:
- Improper Alignment: Make sure the gas strut is installed in the same position as the old one to ensure proper operation.
- Incorrect Pressure: If the gas strut is too stiff or too weak, it may not work properly. Be sure to choose the correct strut for your application.
- Skipping Safety Steps: Always support heavy objects properly during the process. Never try to replace a strut while the object is unsecured.
When to Seek Professional Help
While replacing a gas strut can be a simple DIY task, there are certain situations where it’s better to consult a professional:
- Complex or Integrated Systems: If the gas strut is part of a larger, more intricate mechanism (e.g., on machinery or vehicles), professional help may be required to ensure everything works safely and effectively.
- Uncertain about the Right Strut: If you’re not sure which replacement strut is needed or if you’ve never done this type of repair before, a professional can help guide you through the process.
If you’re unsure about handling the replacement yourself, seeking professional help will ensure that the job is done correctly and safely.
In Closing
Replacing a gas strut yourself is entirely possible for simple applications like a car boot or office furniture. With the right tools, safety precautions, and a bit of know-how, you can complete the job efficiently. However, if you’re dealing with more complex systems or unsure about your skills, it’s always a good idea to consult a professional to avoid mishaps.
