Understanding Coil Springs on the 2018 Toyota Hiace

The 2018 Toyota Hiace is a popular choice in Australia for anyone after a reliable, tough van capable of handling everything from trades work to family trips. When discussing suspension components like coil springs, it's important to first clarify whether coil springs are actually used on this vehicle.

After checking technical sources and manufacturer specifications for the 2018 Toyota Hiace, it turns out that coil springs are not fitted on this model. Instead, Toyota uses a leaf spring suspension setup on the rear axle of the Hiace, paired with independent double wishbone suspension with coil springs only on the front axle. So, coil springs are only relevant to the front suspension, not the rear.

Why no coil springs on the rear? Leaf springs are favoured on the rear of many commercial vans and utes because of their impressive load-carrying capabilities and durability. Leaf springs spread weight more evenly and provide consistent support under heavy loads, which is perfect for the Hiace's role as a workhorse. They are also simpler and more robust, making them easier and cheaper to maintain over time compared to coil springs in high-load applications.

That said, the front suspension of the 2018 Toyota Hiace does rely on coil springs. So if someone is after insight about coil springs in relation to the Hiace, the front suspension is where these springs come into play. Coil springs on the front offer a smoother ride and better handling characteristics compared to leaf springs, which is why Toyota combines coil springs up front with leaf springs at the back. This hybrid setup makes the vehicle comfortable to drive while still being capable of carrying heavy loads.

For those interested in the front coil springs on the 2018 Toyota Hiace, it's handy to understand what they do and why maintaining them is important.

Coil springs are a key part of the suspension system designed to absorb shock and bumps from the road. They compress and expand as the vehicle travels over uneven surfaces, keeping the ride smooth and helping maintain tyre contact with the road for better stability and handling. Without coil springs, driving would feel a lot rougher, as every bump would be transmitted directly to the chassis.

Because the Hiace's front suspension uses coil springs, they work alongside shock absorbers (or struts) to cushion impacts efficiently. Over time, coil springs can weaken or sag, affecting the vehicle's ride height and overall suspension performance. This not only impacts comfort but can also lead to uneven tyre wear and additional strain on other suspension components.

When servicing the 2018 Toyota Hiace, it's a good idea to check the coil springs for signs of wear or damage. Common issues include corrosion, cracks or chips in the spring coils, and sagging. If any of these are noticed, it is recommended to replace the coil springs promptly to maintain safe handling and ride comfort.

Replacing coil springs is usually straightforward but should be done with care. Because they come under a lot of tension, properly equipped mechanics use specialised tools to safely compress and remove the springs. Replacing worn coil springs in pairs is advised to maintain even suspension and balanced handling.

Basic maintenance tips for the coil springs on your 2018 Toyota Hiace include regular visual inspections, especially if you frequently carry heavy loads or drive on rough terrain. Cleaning off dirt and salt can help prevent corrosion, particularly if you live near the coast or in areas where roads are salted in winter. Having your suspension checked during regular service intervals ensures any issues with springs or associated components are caught early.

In short, the 2018 Toyota Hiace does not use coil springs on the rear suspension due to the practicality and durability of leaf springs for heavy loads. However, coil springs are very much part of the front suspension setup, contributing to a comfortable driving experience and good handling. Proper maintenance and timely replacement of these front coil springs are essential for keeping the Hiace running smoothly and safely for years to come.
