Understanding Strut Mounts on the 2019 Holden Commodore

The 2019 Holden Commodore is a well-engineered vehicle, designed with a keen focus on both performance and comfort. When discussing suspension components such as strut mounts, it's essential to recognise how this particular model is put together. Unlike some vehicles that utilise MacPherson strut suspensions with distinct strut mounts, the 2019 Holden Commodore typically employs a double wishbone suspension setup at the front and a multi-link arrangement at the rear. Because of this suspension design, the traditional strut mount you might expect on other cars is not relevant or used on this model.

So, why exactly does the 2019 Holden Commodore not use strut mounts? It comes down to the type of suspension it features. Strut mounts are a crucial component in MacPherson strut systems, which combine the shock absorber and coil spring into a single integrated unit. The strut mount provides a direct mounting point to the vehicle's chassis at the top of the strut assembly. It also acts like a bearing, allowing the strut to pivot when steering, especially at the front end, while also cushioning against vibrations. This helps smooth out road imperfections and maintain proper alignment.

However, the 2019 Holden Commodore's suspension system is different. With its double wishbone front suspension, the coil springs and shock absorbers are separate components rather than a combined strut. Instead of a strut mount, this system uses ball joints, control arm bushings, and shock absorber mounts attached directly to the chassis and control arms. This design offers enhanced handling characteristics and allows for more precise control over wheel alignment, which is why a strut mount is not part of the setup.

While the lack of strut mounts may seem like a minor point, it's actually an important distinction. Because the Commodore does not use MacPherson struts at the front, maintenance and servicing focus differently compared to vehicles that do. Instead of replacing or inspecting strut mounts during suspension servicing, technicians pay close attention to the condition of control arm bushings, ball joints, and shock absorber mounts.

This setup allows for some advantages. The double wishbone suspension and separate shock absorber configuration tend to be more durable in everyday use, as the various components can wear independently without affecting the entire system. For example, if a shock absorber requires replacement, it does not necessitate a new strut mount, as the mounting points are separate and simpler in design.

For 2019 Holden Commodore owners, knowing this helps set clear expectations around suspension servicing. If the car feels unsettled or noises come from the suspension, it's unlikely the issue lies with a strut mount but rather with worn bushings, ball joints, or shock absorber mounts. Service technicians will often recommend checking these components first.

Regular inspection of the suspension system on the Commodore generally includes looking out for signs such as:

• Uneven tyre wear.
• Clunking or knocking noises when driving over bumps.
• Loose or sloppy steering feel.
• Visible cracking, splitting, or deformation of bushings and mounts.

Replacing worn suspension components promptly is critical for maintaining ride quality, steering precision, and vehicle safety. In contrast to some vehicles that demand simultaneous strut mount replacement with shocks or struts, the Commodore's components can be serviced or replaced individually as needed. This can be more cost-effective and less time-consuming for owners.

When servicing suspension, it is also recommended to have a wheel alignment performed afterwards. The double wishbone front suspension benefits from precise alignment to ensure tyres wear evenly and the vehicle tracks straight. This is something Holden dealers and reputable automotive workshops will routinely check during a suspension service.

In essence, the takeaway for anyone looking at the 2019 Holden Commodore is that strut mounts do not feature in this vehicle's front suspension design. Instead, its double wishbone setup uses separate components that serve similar purposes but are maintained differently. Regular inspections and addressing any worn parts like bushings or shock mounts will keep the Commodore driving smoothly for years to come.
