Understanding Gas Struts on the 2010 Subaru Legacy

The 2010 Subaru Legacy is a popular midsize sedan known for its reliability, all-wheel drive capabilities, and comfortable ride. When it comes to gas struts, enthusiasts and everyday drivers alike might wonder if these handy components play a role in this beloved vehicle. Gas struts, also called gas springs or lift supports, are commonly used in cars to assist in lifting and holding open parts like the bonnet, tailgate, or boot lid.

For the 2010 Subaru Legacy, gas struts are indeed fitted, primarily on the boot lid (the rear door that opens to the cargo area). Unlike some vehicles that still rely on traditional mechanical props or torsion bars, Subaru opted for gas struts on the Legacy's boot, making it easier and smoother to open and close the rear hatch. This adds a bit of convenience and comfort for users, especially when their hands might be full.

Gas struts contain a sealed cylinder filled with compressed nitrogen gas and oil. When you lift the boot lid, the gas inside the strut expands, providing a supporting force to counteract the weight of the lid. This means less effort is needed to open the boot, and the strut will hold it securely in the open position without the need for any extra props or manual holding.

The use of gas struts on the boot lid improves user experience in a couple of ways. First, the opening and closing action is smoother and quieter. Second, the struts prevent the lid from slamming shut, reducing the risk of injury or damage. Third, these struts free up both hands for unloading or loading cargo since the boot will stay up on its own. For Subaru Legacy owners, this can really be a welcome upgrade compared to older tilt-and-hold designs.

It's worth noting that while the 2010 Subaru Legacy typically has gas struts on the boot, it does not usually have gas struts on the bonnet. The bonnet is held up with a traditional mechanical prop rod which, although a bit more old-school, is effective and simpler in design. The mechanical prop is less subject to wear from heavy weight or constant opening and closing, which might be one reason Subaru chose to stick with it for the bonnet in this model.

Given the importance of gas struts on the boot lid, maintenance and replacement advice for these parts is quite relevant. Over time, gas struts can lose their pressure, which means they won't hold the boot open properly or could collapse unexpectedly. This usually happens because the gas cylinder develops small leaks or the internal seals wear out with the repeated use of the struts.

For Legacy owners, it's a good idea to check the gas struts periodically, especially if the boot lid feels heavier than usual or doesn't stay open reliably. You can do a very simple test by opening the boot all the way and letting go. If the lid sags down or doesn't stay up firmly, it's a sign the gas struts are wearing out and probably time for replacement.

Replacing the gas struts is not complicated and can be done by a handy DIY enthusiast or a professional mechanic. Gas struts usually come as direct replacements for the car's make and model, with mounting points that clip into place at each end. It's important to replace both gas struts at the same time, even if only one has failed. This ensures balanced support across the width of the boot lid for smooth and safe operation.

When fitting new gas struts, handling them carefully is necessary. They are pressurised and designed to provide controlled force, so forcing them or damaging the seals can shorten their lifespan. It's also recommended to clean the strut rods and mounting brackets regularly. Dirt and grime can damage the seals and lead to premature failure.

For servicing, lubing the pivot points where the gas struts clip in can further improve smooth movement and reduce wearing noises. However, the struts themselves generally should not be lubricated with oil or grease, as that can attract dirt and interfere with their gas seal.

Overall, the gas struts on a 2010 Subaru Legacy's boot are a small but significant feature that adds daily convenience and safety. Maintaining them properly helps avoid frustrating situations where the boot might not stay open, which can be a hazard when loading groceries or gear. Subaru drivers who take care of these components will enjoy a smoother and safer boot operation for years to come.
