Strut Mounts on the 2009 Holden Commodore: What You Need to Know

The 2009 Holden Commodore is a popular choice among Aussie drivers, well-known for its solid performance and reliable suspension setup. When it comes to suspension components like strut mounts, it's important to know if your car actually uses them, what they do, and how you should look after them. So does the 2009 Holden Commodore have strut mounts? Let's take a closer look.

First off, the 2009 Holden Commodore, particularly models built on the VE platform, does not use a traditional MacPherson strut setup on the front suspension. Instead, the Commodore opts for an independent double wishbone suspension layout up front. This configuration uses separate shock absorbers and coil springs rather than the combined strut assembly typical in many other vehicles. Because of this design, the strut mount - which is a critical part in vehicles running MacPherson struts - is not fitted on the Commodore.

So, why is the strut mount not used? The key reason lies in the suspension design itself. MacPherson struts combine the shock absorber and coil spring into one unit, and the strut mount connects this whole assembly to the vehicle's chassis. It serves multiple purposes, such as isolating road noise and absorbing vibrations, while also allowing the strut to pivot when steering. However, double wishbone suspensions, like in the 2009 Holden Commodore, use separate shock absorbers mounted in bushings, and coil springs located independently. Since the shock absorbers do not double as steering components here, there is no need for a strut mount to perform those functions.

That means the 2009 Holden Commodore relies on other components for suspension mounting and steering movement, such as upper and lower control arm bushings, ball joints, and separate shock absorber mounts. These parts handle the isolation, pivoting, and damping functions instead of strut mounts. Therefore, when servicing or maintaining a 2009 Holden Commodore, you won't be dealing with strut mounts but instead checking these other wear points for any issues.

Alright, if you're familiar with strut mounts from other cars and want to understand their role generally, here's a quick rundown. Strut mounts are often overlooked parts but play a crucial role. They're located at the top of the strut assembly and hold the strut to the car's body. They are usually equipped with rubber or polyurethane insulators to help absorb vibrations and noise from the road, making your ride smoother and quieter. On many vehicles, strut mounts also include a bearing that allows the strut to rotate freely during steering. This bearing reduces friction and prevents premature wear on suspension components, which translates to better handling and a longer lasting strut.

In cars that use strut mounts, they're a regular service item when the strut or shock absorber is replaced. Over time, the rubber or polyurethane parts can crack or compress, bearings may wear out, and the whole mount may become noisy or loose. Symptoms like clunking or rattling from the front end, poor steering response, or uneven tyre wear often point towards worn strut mounts. Replacing them ensures the suspension maintains its correct geometry and noise/vibration isolation.

Even though the 2009 Holden Commodore doesn't have strut mounts, this doesn't mean suspension servicing takes a back seat. Quite the opposite - checking the condition of your suspension bushings, control arms, and shock absorber mounts is just as key to keeping your ride comfortable and safe. Worn bushings can cause noises, handling issues, and premature tyre wear, so regular inspection and prompt replacement when needed is important.

During servicing, it's a great idea to get the front and rear suspension components inspected for any signs of wear or damage. Look out for cracked or split rubber, excessive play in ball joints, or leaking shock absorbers. If any issues pop up, getting these parts repaired or replaced will keep the 2009 Holden Commodore driving like it should.

All up, if you own a 2009 Holden Commodore and are wondering about strut mounts, the takeaway is you don't have to worry about them specifically because of the Commodore's double wishbone setup. Instead, give your attention to the other suspension components that do the job of mounting and damping the shocks. Keeping those in good shape will help maintain steering precision and ride comfort for years to come.

So whether you're getting your routine service sorted or thinking about upgrading suspension parts down the road, knowing your car's suspension layout and components is half the battle. If ever in doubt, chat to a trusted mechanic who knows the ins and outs of the Commodore. They'll make sure your suspension stays in top nick so you can enjoy every drive, no matter where the road takes you.
