Strut Mounts on the 2018 Holden Astra: What You Need to Know

The 2018 Holden Astra is a popular compact hatchback known for its comfortable ride and solid handling. When it comes to suspension components like strut mounts, it's important to understand whether these parts are part of the car's setup, what role they play, and why maintaining them is crucial for keeping the Astra driving smoothly. So, does the 2018 Holden Astra use strut mounts? The answer is yes. This model features a front MacPherson strut suspension setup, which utilises strut mounts as a key component.

Strut mounts act as the interface between the suspension strut assembly and the vehicle's chassis. In the MacPherson strut design employed on the front end of the Astra, strut mounts play a dual role. They serve as a secure mounting point for the suspension strut's top, holding it firmly in place while allowing a degree of rotation. This rotation function is vital because the front wheels turn left and right for steering, and the strut mount allows the strut to pivot smoothly as the steering changes direction.

Additionally, strut mounts provide a level of vibration and noise isolation. Being made from rubber and metal components, they absorb road shocks and reduce harshness transmitted into the cabin. This adds to the Astra's famously comfortable ride by softening the impact of bumps and rough surfaces.

Because strut mounts are a small but important part of the suspension system, they can wear out over time. The rubber elements can degrade from exposure to heat, dirt, and water, eventually becoming cracked or brittle. When this happens, drivers may notice clunking noises from the front end, uneven tyre wear, or even a feeling of looseness or vagueness in the steering. These signs suggest the strut mounts are past their prime and in need of replacement.

Replacing strut mounts as part of a regular service or when worn out is a smart move. Not only does it help maintain the vehicle's original ride comfort and steering precision, but it can also prevent further damage to the suspension. For example, a failing strut mount might lead to extra strain on the strut bearing or shock absorber, which can be expensive to repair.

The good news is that strut mounts are generally affordable and widely available for the 2018 Holden Astra. For optimum results, it's best practice to replace the strut mounts whenever the struts or shocks are serviced. This ensures all related components continue to work together smoothly.

During a replacement, the old strut mount is removed along with the shock absorber or strut. The new mount is installed at the top of the strut assembly and secured to the chassis. Technicians will typically check the condition of the strut bearing inside the mount, as a worn bearing can cause steering issues. After installation, a wheel alignment is usually needed to make sure the suspension geometry is correct and the tyres wear evenly.

Maintenance-wise, while strut mounts do not require regular greasing or lubrication, it's wise to inspect them during routine servicing or tyre rotations. Mechanics will look for signs of deterioration such as cracks in the rubber or worn out bearings. Catching issues early can save money and avoid a bumpy or noisy ride.

Given Australia's varied road conditions and climate, factors such as dirt, salt, and temperature can influence how quickly strut mounts wear out. So owners of the 2018 Holden Astra should be mindful if they experience more vibration, unusual noises, or a change in handling feel. Prompt checking by a qualified mechanic can get ahead of more serious wear and tear.

Overall, strut mounts are a small but essential part of the 2018 Holden Astra's front suspension system. They keep the strut securely mounted, allow smooth steering, and dampen road noise and vibration. Proper inspection, maintenance, and timely replacement of these components can keep the Astra driving happily and comfortably for many kilometres on Australian roads.
