Parts for your 2004 Holden Commodore-Struts

Understanding Struts on the 2004 Holden Commodore

The 2004 Holden Commodore is a well-regarded Australian sedan known for its solid build and reliable performance. When it comes to the suspension setup of this vehicle, particularly the role of struts, it's important to clarify a few things. Contrary to some vehicles that utilise struts as part of their suspension system, the 2004 Holden Commodore actually does not use struts at all. Instead, it relies on a different suspension design, mainly featuring shock absorbers along with coil springs and control arms.

So why does the 2004 Holden Commodore skip struts altogether? The answer lies in the suspension design philosophy. Struts are a structural component that incorporates a shock absorber with a coil spring in one unit and also forms part of the steering and suspension linkage, acting as a pivot point. Many modern cars use struts at the front to combine several suspension components into a compact, cost-effective unit. However, the Commodore opts for a more traditional setup where shock absorbers and coil springs work separately. This setup typically involves upper and lower control arms and separate shocks rather than a strut assembly.

The Commodore's front suspension uses a double wishbone design or a similar multi-link arrangement. This method improves handling by allowing precise control over wheel movement and camber angles, which is especially beneficial for a performance-oriented vehicle like the Commodore. Struts tend to be common in MacPherson strut setups, where the suspension is simpler and more vertical, but the Commodore's suspension isn't designed that way.

Because of this, when servicing a 2004 Holden Commodore, discussions about strut replacement or maintenance typically don't come up. Instead, the focus falls on checking and replacing the individual shocks, springs, and other suspension components such as bushings, ball joints, and control arms. These parts collectively maintain the vehicle's ride comfort, handling, and safety.

While it may sound like splitting hairs, understanding the difference between a strut and a shock absorber can help when tackling maintenance or upgrades. Struts combine a shock absorber with structural support for the suspension system, while shocks simply dampen the movement of the springs and suspension without serving as a structural member.

For Holden Commodore owners, maintaining the suspension means looking out for worn shocks, as they play a vital role in absorbing bumps and ensuring the vehicle sticks to the road. Signs that shocks might need attention include excessive bouncing after driving over bumps, leaking hydraulic fluid, uneven tyre wear, or a general feeling of instability during cornering and braking.

Replacement of shock absorbers on the 2004 Commodore is a pretty straightforward process professionally but benefits greatly from being done in pairs (both front or both rear) to maintain a balanced ride. During service, mechanics will also check the condition of coil springs and suspension bushings to ensure the whole system is functioning correctly.

Regular maintenance intervals usually suggest inspecting the shocks every 50,000 km or so, but if the vehicle is often driven on rough roads, hauling heavy loads, or experiencing poor ride quality, sooner inspection is a good idea. Proper maintenance not only prolongs the life of the suspension but also helps keep the driving experience smooth and safe.

In a nutshell, the 2004 Holden Commodore does not have struts as part of its suspension system. Rather, it uses shock absorbers alongside coil springs and control arms. This setup provides a strong, controlled ride that suits the vehicle's driving dynamics. When it comes time for suspension servicing, focusing on shocks and the related components is key to keeping the Commodore handling exactly how it should on Aussie roads.
