Understanding Gas Struts on the 2018 Subaru Forester: Purpose, Maintenance, and Replacement

The 2018 Subaru Forester, like many modern SUVs, is designed with convenience and safety in mind. One essential component that often goes unnoticed but plays a crucial role in everyday use is the gas strut. These handy little devices are fitted to parts of the vehicle such as the tailgate and sometimes the bonnet, assisting in lifting and holding these heavy panels open with ease and stability.

Gas struts, sometimes called gas springs or lift supports, work by using compressed gas trapped inside a cylinder to exert force. This force helps counterbalance the weight of the panels they support, making it easier to open and preventing abrupt closure. On the 2018 Subaru Forester, gas struts are primarily used on the tailgate, providing smooth operation when accessing the rear cargo area.

Why are gas struts important for the Forester? Well, without them, lifting the tailgate could be quite a hassle, as it's a fairly large and heavy door. The struts ensure the tailgate lifts up easily and stays open without needing to be held manually, enhancing user safety and convenience. This is particularly handy for drivers or passengers loading groceries, outdoor gear, or luggage, offering a hands-free opening experience.

Over time, like any mechanical part, gas struts can wear out. They rely on the sealed gas pressure and a smooth piston to function correctly. With frequent use and exposure to the elements, especially the fluctuating temperatures and humidity common in Australia, the gas inside the strut can leak, or seals can degrade. When this happens, the strut loses its ability to hold the tailgate up firmly and might even allow it to slowly close, which can be frustrating or even dangerous.

It's a good idea to give the gas struts a check each time the Subaru Forester has a service. Mechanics often include this as part of a thorough inspection. You might notice signs that your gas struts are struggling if the tailgate feels heavier than usual to lift, doesn't stay open on its own, or closes unexpectedly. In these cases, replacement is usually the best option since gas struts are sealed units and cannot be recharged or repaired easily.

Replacing gas struts on a 2018 Subaru Forester is generally a straightforward and affordable repair. Most aftermarket suppliers offer direct-fit replacement struts that are designed to meet or exceed OEM specifications. It is important to install the correct part number to ensure proper fitment and function. Installation involves simply popping out the old struts from their mounting points and snapping the new ones into place. It typically does not require any special tools, although some basic hand tools may be helpful.

Proper maintenance of your Subaru's gas struts is limited but includes a few simple tips to extend their lifespan. Avoid forcing the tailgate open or closed, as excessive strain can damage the seals inside the struts. Additionally, keeping the mounting points clean and free of rust or debris can prevent wear and ensure smooth operation. Some owners find that applying a light silicone spray to the exposed parts of the struts can help protect against corrosion, but be careful not to spray grease or oil where it might attract dirt or interfere with the seal.

For owners living in harsh coastal or rural regions where salt, dust, or chemicals might accelerate wear, more frequent inspections and prompt replacement of failing struts can prevent unexpected tailgate issues. A failing gas strut on the tailgate might not just be a nuisance, in some situations, a sudden closing tailgate could cause injury or damage. Staying on top of gas strut health is a simple way to keep everyday use of the vehicle hassle-free.

To sum it up, the 2018 Subaru Forester does rely on gas struts to help operate the tailgate smoothly and safely. These components play an important, though humble, role in vehicle functionality, contributing to convenience and safety. Regular checks during servicing, awareness of symptoms of wear, and timely replacement keep these struts working as intended and enhance the overall experience of owning a Forester.
