Parts for your 2013 Holden Commodore-Struts

Understanding the Struts on a 2013 Holden Commodore

The 2013 Holden Commodore, a popular Australian sedan, is well-known for its solid performance and comfortable ride. When it comes to the suspension system of this vehicle, many owners might wonder about the presence and role of struts. Specifically, whether the Commodore actually uses struts as part of its front suspension setup. According to technical manuals and automotive resources, the 2013 Holden Commodore employs a conventional shock absorber and coil spring arrangement on the front suspension rather than MacPherson struts. This means that struts are not part of the design on this particular model.

So, why does the 2013 Holden Commodore not use struts? The answer boils down to the suspension design chosen by Holden engineers for this car. A strut combines the shock absorber and a coil spring into one unit and typically forms a structural component of the vehicle's suspension. Many modern cars, especially smaller or lightweight models, use struts to save space, reduce weight, and simplify the suspension architecture. However, the Commodore's front suspension uses an independent double wishbone setup paired with separate shock absorbers and coil springs.

This double wishbone system allows for greater control over wheel alignment angles throughout suspension travel. It tends to provide a superior balance between ride comfort and handling performance, which is especially important in a performance-oriented car like the Commodore. These advantages outweigh the compactness and simplicity benefits usually associated with strut systems. The use of separate shocks and springs also aids in better load distribution and more durable suspension components, which suit the Commodore's larger body and heavier weight.

Understanding the difference here is key. Struts are commonly found in vehicles using the MacPherson strut design, where the strut unit acts both as a suspension damper and a structural part of the suspension system that locates the wheel hub. In contrast, the Commodore relies on a setup that keeps these functions separate. This is why when discussing the 2013 Holden Commodore's suspension, 'struts' as a component simply do not come into play.

While you won't find struts on the 2013 Holden Commodore, the vehicle still has shock absorbers and springs that require attention. These parts perform many of the same damping and load-support tasks that struts would in other models, so maintenance and replacement should follow similar principles. Understanding these components is just as important for keeping the Commodore running smoothly.

If you're servicing your Holden Commodore, checking the condition of the shock absorbers is crucial. Over time, shocks can wear out from repeated use, leading to a bouncier ride, poor handling, and increased braking distances. Signs that shocks may need replacement include excessive bouncing after a bump, uneven tyre wear, or visible leaking of hydraulic fluid from the shock body. Even though they look different from struts, the shocks work to control spring movement and absorb road impacts, so fresh shocks are essential to maintain vehicle stability and ride comfort.

Alongside shocks, the coil springs support the vehicle's weight and keep the ride height consistent. Over time, springs can sag or corrode, especially in harsh Australian conditions where roads and weather can take their toll. When servicing, mechanics will often check for any cracks, corrosion, or sag in the springs as part of a suspension health check.

Replacing shocks and springs on the 2013 Holden Commodore is generally straightforward for a skilled mechanic. Typically, both front and rear sides are inspected together, since uneven wear can create balance issues. While the separate spring and shock setup can mean a few extra steps compared to strut systems that combine everything into one, it also means each component can be replaced individually as needed, which might save money and complexity for repairs.

Keeping your suspension components in check on the Holden Commodore also contributes to other vehicle systems working properly. For example, well-maintained shocks and springs improve tyre contact with the road, enhancing grip and safety. They also help protect other parts from unnecessary stress, such as the steering components and chassis. Routine servicing generally involves a visual inspection, function check, and sometimes road testing to assess how the suspension performs under normal driving conditions.

There are no fixed intervals like an oil change for shocks or springs but watching for warning signs and getting your suspension evaluated during regular servicing is the best way to stay on top of it. If the car feels unstable, there are noises from the suspension, or handling feels "off," it's time to get the suspension checked. Australian roads can be tough, so many owners find shocks need replacement at around 100,000 to 150,000 kilometres depending on driving style and road conditions.

To sum it up, although the 2013 Holden Commodore does not use struts due to its choice of a double wishbone and separate shock absorber suspension setup, its shock absorbers and coil springs perform the essential roles of damping and support. Regular checks and timely maintenance of these components will keep the car handling safely and riding smoothly for years to come. Keeping this suspension system in good nick is a smart way to maintain the iconic Holden Commodore driving experience on Aussie roads.
