Coil Springs on the 2017 Subaru Forester: Purpose, Maintenance, and Replacement Tips

The 2017 Subaru Forester comes equipped with coil springs as a key component of its suspension system. Coil springs play a vital role in delivering that smooth and comfortable ride most drivers expect from this popular SUV. Before diving into why these springs matter and how to look after them, it helps to understand exactly what coil springs do and why they are important for the Forester.

Coil springs are essentially metal coils that compress and expand to absorb the bumps and shocks from the road surface. On the 2017 Subaru Forester, they work alongside shock absorbers to cushion the impact of uneven terrain, potholes, and everyday driving irregularities. This combination helps maintain tyre contact with the road, improving handling, steering, and safety.

The Forester's coil springs are part of a MacPherson strut suspension setup at the front and a double wishbone style suspension at the rear, both of which rely on coil springs to support the vehicle's weight and absorb road shocks. Unlike leaf springs, which are more common on heavier trucks and off-road vehicles, coil springs offer a more progressive and comfortable response. This is especially beneficial for a vehicle like the Forester, which balances off-road capability with on-road comfort.

When thinking about servicing or maintaining the coil springs on a 2017 Subaru Forester, there are a few things to keep in mind. Typically, coil springs themselves are very durable components and do not require routine replacement unless damaged or showing signs of wear. However, regular inspections are a good idea. Over time, coil springs can become corroded, sag, or even crack, especially if the vehicle is frequently driven in harsh conditions or loaded beyond its specified weight.

During regular servicing, mechanics will usually check the coil springs for any visual signs of damage or wear. This includes looking for cracks, corrosion, or uneven sagging when the vehicle is on a flat surface. If one spring is compromised, it often affects the handling and ride height, which can then lead to uneven tyre wear or other suspension problems.

Aside from visual inspections, it's important to pay attention to how the vehicle rides. If the Forester starts to feel particularly bouncy, uncomfortable, or if the suspension bottoms out over bumps, it could be a sign that the coil springs or related components need some attention. While shock absorbers typically wear out faster, the springs work hand in hand with them, so it's wise to check both when servicing the suspension.

Replacing coil springs on a 2017 Subaru Forester is generally straightforward for a qualified mechanic but requires the right tools and experience due to the stored energy in compressed springs. It is advisable to replace coil springs in pairs - either both front or both rear - to maintain balanced handling and ride quality. Swapping out just one spring can lead to uneven suspension performance.

When ordering replacement coil springs, it's important to source genuine or high-quality aftermarket parts designed specifically for the 2017 Subaru Forester. Using inappropriate springs can affect suspension geometry and potentially compromise safety. Also, pairing new coil springs with fresh shock absorbers is often recommended to keep suspension performance at its best.

Another factor to consider when looking after coil springs is ensuring the vehicle's load is within the manufacturer's specifications. Excessively heavy loads can accelerate spring wear and lead to premature failure. Avoid overloading the Forester if possible, and keep an eye on how additional accessories or roof racks might affect suspension stress.

While coil springs themselves don't require lubrication or other routine maintenance, keeping them clean from mud, salt, or debris can help minimise corrosion risk. If you live in coastal areas or places with heavy road salt use during winter, regular underbody washes can be beneficial. This simple step helps prolong the life of the springs and other suspension components.

For those who enjoy off-roading or use their Forester in challenging conditions, it's a good idea to inspect suspension components more frequently. Harsh terrain, water crossings, and rough tracks can all place extra strain on coil springs and related parts, increasing the chance of wear or damage.

All up, coil springs on the 2017 Subaru Forester are essential for keeping the ride smooth, handling sharp, and safety uncompromised. Taking a bit of care with regular inspections, sticking to appropriate loading limits, and replacing worn springs in pairs will ensure the Forester's suspension stays healthy for years to come. It's one of those parts that quietly does its job until it's time to give it some attention, but when maintained well, it delivers comfort and confidence every time you get behind the wheel.
