Understanding Control Arms on the 2016 Toyota Hiace: What You Need to Know

The 2016 Toyota Hiace is a popular workhorse across Australia, known for its reliability and ruggedness. When it comes to suspension components like control arms, it's important to understand whether these parts are actually part of the vehicle's design and, if so, what role they play. For the 2016 Hiace, the setup is a bit different from many typical passenger cars due to its commercial vehicle roots and body-on-frame chassis.

On the 2016 Toyota Hiace, particularly the versions sold with the high-roof van layout or the single or dual cab chassis, traditional front control arms do exist but are part of a specific front suspension design. This vehicle uses a double wishbone suspension system at the front, which includes upper and lower control arms. These control arms connect the front wheels to the frame, allowing controlled movement and maintaining proper alignment throughout the ride. Meanwhile, the rear suspension generally employs leaf springs rather than control arms because the Hiace is primarily built for load carrying and durability rather than sophisticated independent rear suspension handling.

So, whether you are driving a LWB Hiace van or a dual cab, understanding control arms in the front is relevant. These components are crucial to maintaining the smooth handling, steering precision, and overall safety of the vehicle, especially when it's loaded up with gear or passengers.

Let's break down the role of control arms a bit more and why they're essential on the 2016 Toyota Hiace.

Control arms are basically the link between the vehicle's chassis and the wheels, acting like pivot points that allow the wheels to move up and down when going over bumps or uneven ground, while also keeping the wheels aligned and steady during cornering or braking. On the Hiace, the front control arms are part of the double wishbone setup, which helps the van handle better than some other commercial vehicles that have simpler suspension designs. The dual arms (upper and lower) work together to distribute forces and maintain wheel positioning.

Without healthy control arms, you'd notice a number of problems, including uneven tyre wear, steering wander, clunking noises when going over bumps, and degraded ride comfort. Worn control arm bushings or ball joints - both integral parts of the control arm assembly - can also compromise your safety by causing poor vehicle control.

Now, when it comes to servicing and maintenance of control arms on the 2016 Toyota Hiace, there are a few key tips to keep in mind:

1. Regular Checks During Servicing - Mechanics typically inspect the control arms and their bushings and ball joints during routine vehicle servicing or suspension checks. This inspection helps spot any cracks, excessive wear or damage before they become a serious problem.
2. Listen For Signs of Wear - If a driver hears a knocking or clunking noise from the front end when driving over bumps, or if there's noticeable play in the steering, it's a good idea to get the control arms examined as these are common symptoms of failing components.
3. Tyre Wear Patterns - Uneven or rapid tyre wear on the front axle can also indicate that control arms or their bushings are worn, leading to misalignment.
4. Replacement Considerations - When control arms or their associated parts like ball joints or bushings wear out, replacement is the best option. Toyota Genuine Parts are recommended for the best fit and durability. Fitting aftermarket components can be acceptable if they meet appropriate quality standards but always ensure that the replacement parts are compatible with the specific variant of the 2016 Hiace.
5. Don't Delay Repairs - Postponing maintenance or replacement of worn control arms not only reduces comfort but may cause further damage to suspension, steering components, or tyres, eventually leading to higher repair costs and increased safety risks.

It's worth noting that while the rear suspension of the 2016 Hiace does not use control arms, relying instead on leaf springs for load support, the front control arms play an important role in vehicle handling and safety. This hybrid approach is common in commercial vans, balancing rugged load-carrying capability with a reasonable ride quality.

For those owning or maintaining a 2016 Toyota Hiace, awareness of the front suspension's control arms, their function, and maintenance requirements will help keep the van driving safely and smoothly across countless Queensland highways, Sydney's urban streets or the rugged outback roads of Western Australia. A quick check of the control arms during regular servicing means you avoid surprises and stay confident behind the wheel.

So, if there's ever any doubt about the condition of your Hiace's suspension, especially after driving through rough terrain or experiencing unusual driving behaviour, it's a smart move to get the control arms inspected. Taking care of these small suspension details goes a long way in maintaining your trusty 2016 Toyota Hiace's dependable reputation.
