Understanding Struts on the 2017 Holden Astra

The 2017 Holden Astra is a popular hatchback and sedan in Australia known for its sporty handling and comfortable ride. When it comes to its suspension, many wonder about the presence and role of struts, especially since the term "struts" often pops up in discussions about car suspension systems. So, does the 2017 Holden Astra use struts in its suspension setup? And if it does, what does that mean for maintenance and replacement?

First things first: the 2017 Holden Astra predominantly features a MacPherson strut setup at the front suspension. MacPherson struts are essentially a combination of a shock absorber and a coil spring in one unit. They provide both structural support and damping, absorbing road shocks and helping maintain tyre contact with the road. The rear suspension on the Astra typically uses a torsion beam or multi-link design that doesn't employ struts but rather uses separate shock absorbers and springs.

So, why does the Astra use struts at the front but not at the rear? The front struts play a crucial role in steering and handling. Because the front wheels need to both steer and absorb road impacts, a strut design is ideal for combining these functions efficiently. The MacPherson strut is compact, lightweight, and cost-effective, making it a popular choice for many front-wheel-drive vehicles like the Astra. On the other hand, the rear suspension doesn't need to steer, so it often uses different setups that prioritise comfort or packaging space, which is why struts are not fitted at the rear in most Astra models.

For drivers and owners of the 2017 Holden Astra, understanding the function of the front struts is key when considering suspension health. The struts not only support the weight of the front end but also absorb bumps and keep the vehicle stable during cornering or rapid maneuvers. Worn or damaged struts can lead to issues such as poor steering response, uneven tyre wear, excessive body roll, and uncomfortable rides.

When it comes to servicing and maintaining the struts on the 2017 Holden Astra, regular inspection is a good rule of thumb. Signs that the struts might need attention include:

• Excessive bouncing after hitting potholes or speed bumps
• Visible leaks of hydraulic fluid on or around the struts
• Uneven or cupped tyre wear on the front tyres
• Pulling to one side while driving or during braking
• Knocking or clunking noises coming from the front suspension

When any of these symptoms show up, it's best to get the suspension checked out by a qualified mechanic. Strut replacement is not always an urgent job but can quickly become necessary to maintain safe handling and ride comfort. Mechanics typically recommend replacing struts in pairs (left and right sides) to keep the suspension balanced.

The actual replacement of a front strut on the 2017 Holden Astra involves removing the entire strut assembly - spring, shock absorber, and mounts - and installing a new unit. It's important to have this done professionally because it requires special tools, like a spring compressor, and proper alignment afterwards to ensure safety and performance.

Besides replacement, some maintenance tips to extend the life of the struts include avoiding harsh impacts such as hitting kerbs or potholes at speed and keeping the suspension components clean and free of rust or dirt buildup. Regular wheel alignments help reduce stress on suspension parts as well.

Struts may not be the most glamorous part of a vehicle, but on the 2017 Holden Astra, they play an essential role in the driving experience. Keeping them in top shape ensures the car remains stable, comfortable, and safe for everyday Aussie roads. If it's been a while since the suspension was last checked or if there's a feeling that the ride isn't quite right, giving those front struts a closer look can make all the difference.
