Parts for your 2017 Lexus Is-Struts

Understanding the Struts on the 2017 Lexus IS

The 2017 Lexus IS is known for its sporty handling and comfortable ride, and a large part of that comes down to its suspension setup. When it comes to the role of struts on this vehicle, it's important to clarify a few things by referencing technical sources and official Lexus specifications. The 2017 Lexus IS uses a multi-link suspension system at the rear and a MacPherson strut front suspension. This means struts are definitely present on the front of the vehicle but not on the rear.

So why are struts fitted to the front and not the rear of the 2017 Lexus IS? It all boils down to the design objectives and the type of suspension used. Struts combine the shock absorber and the coil spring into a single unit, playing a dual role in both absorbing bumps and supporting the vehicle's weight. This compact design is ideal for front suspensions, especially in vehicles like the Lexus IS which use MacPherson struts in front to save space and reduce weight. The strut assembly also provides a straightforward mount point for the steering mechanism, which is crucial for precise handling.

On the other hand, the rear end of the 2017 Lexus IS features a multi-link suspension setup. Multi-link suspensions use separate components for the coil springs and shock absorbers instead of integrally combining them into a strut. This arrangement offers improved handling dynamics and ride comfort near the rear wheels. It gives independent movement across multiple axes, providing the sporty yet composed ride Lexus IS owners expect. The multi-link design is often favoured for rear suspensions of performance-oriented sedans because it balances the trade-off between comfort and handling by isolating road shocks more effectively.

That means, if someone is looking specifically for information or advice on 'struts' for their 2017 Lexus IS, it generally refers to the front suspension only. The rear suspension shouldn't be referred to as struts because it is not a strut-type system. Instead, rear shocks and separate coil springs perform the suspension roles.

For those wanting a deeper look, here's a rundown on the struts fitted to the front of the 2017 Lexus IS and some tips on replacement and maintenance.

The struts on the front of the Lexus IS are a key part of the MacPherson strut suspension. They connect the steering knuckle with the car body and absorb impacts from road irregularities. Because struts carry the weight and help with steering, they are vital for safety and handling. If struts wear out, owners may notice things like excessive bouncing over bumps, poor steering response, unusual noises, or uneven tyre wear.

When it comes to replacing struts on a 2017 Lexus IS, it's handy to have some guidance. Struts generally last somewhere between 80,000 to 160,000 kilometres depending on driving habits and road conditions. If the car is driven on rough roads frequently or carries heavy loads, the struts might degrade faster. Signs that replacement is needed include leaking fluid from the strut assembly, consistent knocking sounds when driving over bumps, and a sagging or uneven stance at the front of the car.

Struts replacement should ideally be done in pairs (both front struts at the same time). This prevents uneven handling and promotes balanced suspension performance. Fitting new struts can restore the Lexus IS's crisp steering feel and improve ride comfort. Since these struts incorporate the coil spring, care must be taken during replacement. It's a job best left to professionals who have the right tools and knowledge to safely compress springs, detach components, and fit new assemblies.

For ongoing maintenance, periodic inspections during routine servicing can catch early signs of strut wear. Mechanics will usually check for leaks, check the condition of the rubber mounts and bushings, and listen for any abnormal noises. Keeping tyres properly inflated and aligned also helps extend strut life by reducing unnecessary stress on suspension parts. And, if any front-end collisions or impacts happen, a suspension check is definitely a good idea to ensure the struts and related components aren't damaged.

Owners aiming to keep their 2017 Lexus IS running at peak comfort and performance should not overlook the importance of healthy struts. These humble components do a lot of work, controlling ride and handling every time the car hits a bump or takes a corner. Being attentive to their condition, listening for unusual noises, and following recommended service intervals contributes to a safer and more enjoyable driving experience.

Ultimately, while the 2017 Lexus IS doesn't use struts all around, the front MacPherson struts are crucial for the car's suspension system. Knowing their role and how to care for them helps keep this luxury sedan handling sharp and riding smoothly across Aussie roads.
