Coil Springs on the 2017 Toyota Avensis: What You Need to Know

The 2017 Toyota Avensis is a dependable mid-sized family car that is known for its comfortable ride and solid build quality. When it comes to suspension components, coil springs are a key feature on this model. Coil springs play an important role in the vehicle's suspension system, helping deliver a smooth and controlled driving experience. Let's take a closer look at what coil springs do on the 2017 Toyota Avensis and why maintaining them is essential for keeping the car in good shape.

Coil springs are those heavy-duty, spiral-shaped pieces of metal that sit between the wheels and the vehicle's frame. They compress and expand to absorb bumps and uneven surfaces on the road, ensuring passengers don't feel every little imperfection. Essentially, they act as the cushioning system for the car, working alongside shock absorbers or struts to provide that smooth ride.

On the 2017 Toyota Avensis, coil springs are indeed fitted both on the front and rear suspension systems. The front suspension uses a MacPherson strut design, which incorporates coil springs wrapped around a shock absorber. Meanwhile, the rear suspension typically involves a double wishbone or multi-link setup with coil springs. This combination strikes a balance between comfort and handling, which is exactly what many drivers expect from the Avensis.

Why does the Avensis use coil springs rather than other spring types like leaf springs or torsion bars? It comes down to ride quality and handling. Coil springs are favoured in passenger vehicles because they're lighter and provide more consistent spring rates. They also allow for more compact and flexible suspension setups, which means better handling without sacrificing comfort. In a family car like the Avensis, that means a smooth, composed ride, easy cornering and stability at higher speeds.

Replacing or maintaining coil springs doesn't have to be a complicated process, but it's definitely important. Over time, coil springs can wear out, corrode or even break, especially if the car is driven on rough roads or heavily loaded frequently. When coil springs start to sag or fail, it can lead to uneven tyre wear, poor ride quality, and potentially affect vehicle safety.

Here are a few signs that might indicate the coil springs on a 2017 Toyota Avensis need some attention:

• The car sits noticeably lower on one side.
• Unusual noises such as clunking or knocking when going over bumps.
• A rough or bouncy ride that seems worse than usual.
• Tyres wearing unevenly or unusual steering behaviour.

It's a good idea to have the coil springs checked during regular servicing or if any of the above symptoms crop up. While coil springs themselves don't usually require frequent replacement, the environment under a car can be harsh. Dirt, moisture and road salt can cause corrosion, especially around the spring seats and mounts. Rusted or weakened springs should be replaced promptly to keep the suspension performing well.

When replacing coil springs on the 2017 Toyota Avensis, it is best to replace them in pairs on the same axle. This is because springs wear and settle over time, so putting one new spring alongside an old one may cause uneven suspension and handling imbalances. Proper installation also requires the use of suitable tools like spring compressors to safely remove and fit the springs without damaging other parts or causing injury.

Besides the springs themselves, it's also wise to check related components such as shock absorbers, strut mounts, and rubber bushings during suspension servicing. Sometimes, issues that seem like worn springs are actually due to other suspension parts wearing out. A professional mechanic can advise on the best course of action and ensure that the whole system works together seamlessly.

Taking care of coil springs will contribute significantly to the longevity of the Toyota Avensis's suspension system. Good spring health means better ride comfort, improved safety, and helps protect other related components from premature wear or damage. For owners who want their 2017 Avensis to keep running smoothly and comfortably, regular inspections of coil springs should be part of the routine.

So, if you're cruising down the highway or navigating suburban streets, remember that those coil springs are quietly doing a lot of hard work. Keeping them in tip-top shape ensures that every drive feels as comfortable and controlled as the day the Avensis rolled off the production line.
