Coil Springs on the 2018 Subaru Legacy: What You Need to Know

The 2018 Subaru Legacy comes equipped with a suspension system that includes coil springs, making them an integral component of the vehicle's ride and handling. Coil springs play a vital role in ensuring comfort, stability, and overall driving quality, especially for a sedan like the Legacy that balances everyday usability with a touch of sportiness.

Coil springs are used in the Subaru Legacy's front and rear suspension setups. These springs compress and expand in response to the road surface, absorbing bumps and road imperfections to provide a smooth ride. They work in conjunction with the shock absorbers to control the vertical motion of the wheels and the body of the car, preventing excessive bouncing and improving grip through corners.

For owners of the 2018 Subaru Legacy, understanding the purpose of coil springs and how to maintain them is key to prolonging the life of their vehicle's suspension and maintaining that signature Subaru comfort and control.

Coil springs are essentially tightly wound metal coils designed to flex under pressure. When the car hits a bump, the springs compress to absorb the impact. Once the bump is passed, the springs expand back to their normal shape, helping to stabilise the car's body. This cycle reduces the severity of shocks felt inside the cabin, allowing for a more pleasant driving experience.

Apart from ride comfort, coil springs also contribute to the car's stability and handling. They support the weight of the vehicle and manage the way the car leans during acceleration, braking, and cornering. For the Subaru Legacy, which often deals with varied Australian road conditions - from uneven suburban streets to highway cruising - these components are essential in preventing excessive body roll and maintaining precise steering response.

When it comes to maintenance, coil springs themselves usually last quite a long time without needing replacement. However, they are a wear item and can degrade over time due to metal fatigue, corrosion from road salt or moisture, and repeated stress from rough roads. It's typical for coil springs to maintain their performance over many years, but signs that they may need attention include unusual noises like creaking or clunking, uneven ride height, or a noticeably bumpier ride.

During routine servicing of the 2018 Subaru Legacy, mechanics should check the condition of the coil springs along with other suspension components. While coil springs do not usually require regular replacement, if they become weak or damaged, they can affect the vehicle's handling and could potentially lead to uneven tyre wear or even suspension failure. Checking for rust, cracks, or sagging springs is part of a thorough suspension inspection.

Replacing coil springs on the Legacy is a straightforward process for a qualified technician, but it's not typically a DIY job due to the tension held within the coils themselves. Professional tools and expertise are needed to safely remove and fit new coil springs without damaging surrounding components or risking injury. When springs are replaced, it is usually recommended to replace them in pairs (both front or both rear) to maintain balanced suspension performance.

In addition to the springs themselves, it's a good idea to inspect the associated shock absorbers and strut mounts at the same time. Worn shocks can place extra strain on coil springs, causing them to wear out harder than they should. Addressing these parts together ensures that the Legacy's suspension system continues to work harmoniously and deliver the comfortable drive Subaru owners expect.

Thankfully, parts for the 2018 Subaru Legacy are readily available, and coil springs specifically are designed to meet the vehicle's original specifications. This ensures that once replaced, the suspension retains its intended ride height, stiffness, and ride characteristics.

Maintaining coil springs is really about recognising when they are no longer performing as they should and having them inspected regularly as part of scheduled servicing. For Legacy owners who frequently drive on rough or unsealed roads, more frequent checks might be advisable, since challenging road conditions accelerate wear on suspension components.

With regular attention and timely replacement if required, coil springs will continue to provide the Legacy with its smooth ride, solid handling, and confident road manners. This keeps not only the driver and passengers comfortable but also helps to maintain vehicle safety through steady, predictable handling.
