Tailgate Gas Struts: What They Are and When to Replace Them

Tailgate gas struts (also known as gas springs or shock absorbers) are essential components in vehicles that help support the tailgate or trunk, making it easier to open, hold it in place when open, and close it smoothly. They are designed to ensure that the tailgate operates efficiently, without any sudden movements or difficulty when lifting and closing.

What Are Tailgate Gas Struts?

Tailgate gas struts are hydraulic or gas-powered components designed to assist in opening and closing the tailgate. Inside the strut is a pressurized gas (often nitrogen), which creates resistance and helps the strut to extend and compress as the tailgate moves. This gas pressure provides the necessary force to hold the tailgate in place when open and control its descent when being closed.

These struts are typically installed either at the top or sides of the tailgate, and they are responsible for making the tailgate lighter and easier to operate. They prevent the tailgate from slamming shut too quickly or falling under its own weight.

When Should You Replace Tailgate Gas Struts?

Like any mechanical part, tailgate gas struts wear out over time. Below are some signs that it's time to replace them:

1. The tailgate no longer opens fully: If the tailgate doesn't stay fully open or opens only halfway, the gas struts might no longer be able to support the weight of the tailgate, indicating they need replacing.

2. The tailgate falls while open: If the tailgate tends to fall on its own after you've opened it, it's a strong sign that the gas struts aren't holding it in place anymore. This can be dangerous and should be addressed promptly.

3. Difficulty opening or closing the tailgate: If you find the tailgate unusually heavy or difficult to lift or close, this could mean the gas struts are no longer providing the necessary assistance.

4. Strange noises: If you hear unusual noises like popping, clicking, or grinding when opening or closing the tailgate, the gas struts might be damaged or failing and need to be replaced.

How to Replace Tailgate Gas Struts?

Replacing gas struts is generally an easy task, and it can often be done without professional help. Here's a basic guide:

1. Purchase the correct replacement gas struts: Make sure to buy gas struts that are compatible with your vehicle model. Check the specifications for the right force and size for your tailgate.

2. Remove the old gas struts: Gas struts are usually secured by clips or pins. You can use a flathead screwdriver or a special tool to gently detach the old struts. Be careful not to damage any surrounding parts during removal.

3. Install the new gas struts: Place the new struts in the same position as the old ones and securely attach them. Most gas struts are designed to click into place easily, but ensure they are firmly attached.

4. Test the tailgate: Open and close the tailgate a few times to ensure that the new gas struts are working properly. The tailgate should open fully, stay open securely, and close smoothly.

Conclusion

Replacing the tailgate gas struts when needed is a simple yet crucial task to ensure the proper functioning of your vehicle. If you notice any of the signs mentioned above, it's best to replace them as soon as possible to avoid any inconvenience or safety issues. If you're not confident doing the replacement yourself, it's always a good idea to consult a professional mechanic. Your vehicle's functionality and your safety will thank you!
