Parts for your 2012 Lexus Is-Struts

Understanding the Role of Struts on a 2012 Lexus IS

The 2012 Lexus IS is a sophisticated vehicle that features a well-engineered suspension system designed to deliver a smooth and controlled ride. When exploring the suspension components, you might wonder if struts are part of the setup. Technically speaking, the 2012 Lexus IS primarily uses a double wishbone front suspension combined with a multi-link rear suspension. Struts, as a specific type of suspension component combining a shock absorber and a coil spring into a single unit, are generally not fitted on this model.

Why is that important? Well, the double wishbone setup used in the front of the 2012 Lexus IS offers more precise control of wheel alignment and better handling characteristics, which is one of the reasons why struts are not part of the front suspension system. Struts are often chosen for their compact design and cost-efficiency in front suspensions, especially on vehicles with MacPherson struts, however, the Lexus IS's double wishbone layout provides superior performance for a luxury sports sedan, favouring separate shock absorbers and springs instead.

At the back, the 2012 Lexus IS utilises a multi-link design that similarly does not use struts. This multi-link configuration allows for better wheel movement control and independent rear suspension dynamics, enhancing ride comfort and road-holding capabilities. Like the front, the rear suspension separates the shock absorber and spring components rather than combining them into a strut unit.

So, in simple terms, the 2012 Lexus IS does not come equipped with struts either at the front or the rear. Instead, it uses individual shock absorbers and coil springs fitted in double wishbone and multi-link setups respectively. These designs are preferred for their ability to optimise handling, ride comfort and alignment precision, something the Lexus engineers prioritised to distinguish it from more mainstream models that do commonly use struts.

For those who may be new to automotive parts, struts are often considered a 'jack of all trades' within a suspension system. They provide not only damping like shock absorbers but also bear structural load and control wheel movement in a simpler and often more compact design. This makes them highly popular across many smaller or mid-sized vehicles, but performance-focused and luxury models like the Lexus IS opt for separate spring and damper setups to push handling and comfort further.

While the 2012 Lexus IS does not use struts, it still requires regular attention to the suspension components it does have. Shock absorbers on the 2012 Lexus IS play a crucial role in absorbing road impacts and maintaining tyre contact, which is key to safety and driving enjoyment. Over time, these shocks can wear out, leading to less effective damping, increased body roll, and uneven tyre wear.

Regular suspension checks are recommended during servicing, where mechanics look for leaks, damage, and gauge the ride quality. If shocks or springs are found to be worn or damaged, replacing them is essential. A worn shock or spring can make the vehicle feel bouncy or unstable, affecting both comfort and safety.

When it comes to shock absorber replacement on a 2012 Lexus IS, it's best to use genuine or OEM-grade parts to maintain the performance Lexus designed. Professional installation ensures the suspension geometry remains correct, and wheel alignment should always be checked after any suspension work to prevent handling issues or uneven tyre wear.

Suspension maintenance on the Lexus IS also includes inspecting other components like bushings, ball joints, and mounts. These parts support the shocks and springs, and if they are worn out, they can cause noise and affect the vehicle's handling stability.

In everyday driving, keeping an eye out for signs like a rough ride, unusual noises when going over bumps, or a general feeling of instability can help pinpoint when suspension servicing is needed. Even though struts aren't part of the suspension on this model, the principles of maintaining damping and spring components remain the same.

Ultimately, the 2012 Lexus IS's suspension is designed for drivers who enjoy a balanced blend of performance, comfort and safety, with sophisticated components doing the work behind the scenes. While it may not have struts installed, the shocks and springs fitted are just as important and should be treated with the same care and attention during servicing to keep the vehicle driving exactly as Lexus intended.
