Parts for your 2017 Toyota Hiace-Control arms

Understanding Control Arms on the 2017 Toyota Hiace

The 2017 Toyota Hiace is a sturdy and reliable commercial van popular across Australia for its practicality and durability. When it comes to suspension components, one might wonder whether control arms feature in the Hiace's setup and what their role is if they do.

For the 2017 Toyota Hiace, it's important to note that control arms are not part of its front suspension design. Unlike many passenger cars that use independent front suspension systems incorporating control arms, the Hiace uses a different suspension arrangement that does not require traditional control arms.

The front suspension of the 2017 Toyota Hiace typically consists of double wishbone (also called A-arm) architecture combined with coil springs and stabiliser bars. These A-arms, sometimes referred to as control arms, serve to connect the suspension upright to the vehicle frame, allowing vertical wheel movement while maintaining precise steering and handling. However, in the context of the Hiace, "control arms" as a distinct and separate part name does not commonly appear in technical documentation because the suspension components are integrated differently than on standard passenger cars.

At the rear, the Toyota Hiace uses a leaf spring suspension system rather than an independent setup, which means there are no control arms involved at the back.

Given this suspension design, the term "control arms" is not widely applicable standalone on the 2017 Toyota Hiace. Instead, the suspension control is achieved through double wishbone style arms up front and leaf springs at the rear. This means if someone is searching to replace or maintain "control arms" on a 2017 Hiace, they are more likely dealing with the upper or lower suspension arms in the front wishbone assembly rather than a separate control arm part like you'd find on many passenger cars.

So why does the 2017 Toyota Hiace not use standard control arms as commonly understood? It largely comes down to the vehicle's purpose and design priorities. The Hiace prioritises load-bearing capacity and robustness, essential for commercial use. Leaf springs at the rear provide a tough, durable springing system capable of handling heavy payloads without the complexity or cost of independent rear suspension arms. Up front, the double wishbone setup used is highly regarded for strength and good handling, but the design integrates the arms as part of the suspension assembly rather than standalone control arms.

When it comes to maintenance or replacement of these front suspension arms, which serve the purpose similar to control arms in other vehicles, it's important to keep them in good condition to ensure the Hiace handles safely and comfortably on Australian roads. Worn or damaged suspension arms can lead to uneven tyre wear, poor handling, and a rough ride.

Regular inspections during servicing are recommended to catch any wear in bushings or ball joints attached to these arms. Clunking noises, steering wander, or uneven tyre wear might signal that a suspension arm or its components need attention.

• Check suspension arms and bushings for cracks, damage, or excessive wear
• Listen for unusual noises when driving over bumps or turning
• Inspect wheel alignment and tyre wear patterns regularly
• Replace worn arms or bushings promptly to maintain handling and safety

When replacement is needed, it's best to use genuine or high-quality aftermarket parts designed specifically for the 2017 Toyota Hiace to ensure correct fitment and durability. Professional installation is also recommended to maintain suspension geometry and performance. Incorrectly fitted suspension components can lead to premature wear or compromised vehicle stability.

Whether used for deliveries, trades, or as a people mover, keeping the suspension arms of a 2017 Hiace in good condition enhances driving confidence, load handling, and vehicle longevity. Don't overlook these essential components during your regular servicing - it's a small task that pays off in safety and comfort for everyday journeys.
