Understanding Strut Mounts on the 2017 Holden Commodore

The 2017 Holden Commodore, a well-known Australian sedan, doesn't actually use strut mounts because it is primarily equipped with a double wishbone front suspension setup rather than a MacPherson strut design. Strut mounts are components specifically designed for vehicles that use strut-type suspension systems, which combine the coil spring and shock absorber into a single unit. Since the Commodore uses a different suspension design, the typical strut mount part you find on some cars simply isn't relevant here.

So why is the strut mount not used on the 2017 Holden Commodore? The key is understanding the kind of front suspension setup the vehicle has. The Commodore's front suspension uses upper and lower control arms (also called double wishbones) with separate shock absorbers and coil springs. This design distributes forces differently and mounts the shock absorbers and springs in a way that doesn't require a strut mount. Instead, the shock absorbers are attached directly to the chassis and the control arms, eliminating the need for that rubberised strut mount found on MacPherson strut suspensions.

Strut mounts serve multiple roles on vehicles that have MacPherson strut suspension. They act as the mounting interface between the strut assembly and the vehicle chassis, absorb vibrations and impacts, and often include a bearing to allow the strut to rotate when steering. All these functions are critical for vehicles using strut suspensions to ensure ride comfort, reduce noise, and allow smooth steering operation.

Since the 2017 Holden Commodore uses a more traditional double wishbone setup, it relies on other components like bushings in the control arms and separate shock absorber mounts to perform these duties. These components work together to provide a balanced ride and solid handling without the need for strut mounts.

That said, understanding what a strut mount does can be helpful if comparing the Commodore to other vehicles or if working on a suspension system. Strut mounts usually consist of a metal plate, a rubber isolator, and sometimes a bearing or bearing race. The rubber isolator dampens road noise and vibrations, preventing them from being transmitted to the vehicle's cabin. The bearing, when fitted, allows the top of the strut assembly to pivot smoothly, which is essential for proper steering and control.

For vehicles that do have strut mounts, servicing them is an important part of suspension maintenance. Strut mounts can wear out over time due to constant pressure, road vibrations, and exposure to elements. When they begin to fail, symptoms might include clunking noises during cornering, increased vibration felt through the steering wheel, uneven tyre wear, or a general decline in ride comfort.

Replacing strut mounts can often be a tricky job since it usually involves disassembling the strut assembly, which is under spring pressure. Professional tools like spring compressors are essential to do the job safely. While some do-it-yourself enthusiasts successfully replace strut mounts themselves, it is generally advised to have the work done by a qualified mechanic to avoid injury and ensure the suspension geometry is maintained.

During routine servicing, particularly when shock absorbers or struts are replaced, inspecting the strut mounts for wear or damage is a wise move. Replacing worn strut mounts at the same time as shocks can save money in the long run and restore the original ride quality. Additionally, the type and quality of replacement mounts can influence the ride and handling - opting for OEM or high-quality aftermarket parts is usually recommended.

So even though the 2017 Holden Commodore doesn't use strut mounts, if you're working on a vehicle that does, it pays to understand their role. They play a vital part in the suspension's performance and comfort. For Commodore owners, focusing instead on the condition of control arm bushings, shock absorber mounts, and related suspension components will keep your ride smooth and handling sharp.
