Control Arms on the 2020 Lexus IS: What They Do and Why They Matter

When it comes to the 2020 Lexus IS, control arms play an important role in the vehicle's suspension system. If you're wondering what control arms are and whether your Lexus IS has them, the answer is yes - they do. Control arms are a crucial component in most modern cars, including the 2020 Lexus IS, helping to keep the ride smooth, the handling sharp, and the overall driving experience safe and enjoyable. Let's dive into what control arms are all about, why they're used on the Lexus IS, and why checking them during servicing makes good sense.

First off, control arms are part of the suspension system that connects the chassis of the car to the wheel hubs. They serve as a critical link that helps the wheels move up and down independently of the car's body. This is super important because roads are rarely perfectly flat, and the suspension system is there to absorb bumps and dents, giving the driver and passengers a comfortable ride. On the 2020 Lexus IS, control arms are fitted both at the front and the rear suspension setups, depending on the model and options.

What makes control arms stand out is their design, which allows them to pivot. This pivoting action enables the wheels to move vertically but stay correctly aligned with the road surface. Without control arms, the wheels would just bounce all over the place causing unpredictable handling and an uncomfortable ride. Whether the IS is cruising down the freeway or cornering through tight bends, control arms help maintain stability and ride quality.

The control arms also house bushings, which are rubber or polyurethane components that cushion the connection points, minimising vibration and noise. These bushings absorb a lot of the stress and wear that happens during driving, especially when hitting potholes or uneven surfaces. Over time, these bushings can wear out, and that's when you might notice symptoms such as clunking noises, uneven tyre wear, or a loose feeling in the steering. For a luxury sedan like the Lexus IS, keeping these components in top shape is even more important because it helps preserve that smooth, refined ride the car is known for.

When the time comes to service the control arms on your 2020 Lexus IS, there are a few key things to keep an eye on. Mechanics will usually inspect the control arms for any signs of damage, corrosion, or excessive wear. The bushings and ball joints attached to the arms are also thoroughly checked. If any cracks, tears, or looseness appear, replacement might be necessary to keep the suspension functioning perfectly. Often the ball joints are integrated with the control arm, so any major damage here means the whole arm might get swapped out.

Replacing control arms is not a job that should be skipped or delayed. If worn or damaged control arms keep operating, they can cause the car's suspension geometry to go out of alignment. This leads to poor handling, increased tyre wear, and even safety risks during emergency steering. On top of that, a well-maintained suspension contributes to better fuel economy because the tyres maintain optimal contact with the road. For a 2020 Lexus IS owner, investing in regular suspension checks and control arm maintenance is a smart way to keep the car driving like new.

The good news is that replacing control arms on the Lexus IS isn't overly complicated, but it should be done by someone with the right experience and tools. The process involves lifting the vehicle, removing the wheel, and taking out the worn control arm before bolting in the new one. It's important that once control arms are replaced, a full wheel alignment is carried out to ensure everything is set up perfectly. Without this, the vehicle can still suffer from poor handling and uneven tyre wear.

One more thing to mention is that control arms are designed to endure a lot of stress, but they can still suffer damage from road impacts such as crashing into kerbs or potholes. So, Lexus IS owners who regularly drive on rough or gravel roads may find they need to pay extra attention to their suspension during service visits. Even small amounts of wear or damage can lead to bigger problems down the track.

To look after control arms on a 2020 Lexus IS, owners should have their suspension inspected at routine service intervals, or sooner if they notice steering issues or unusual noises. Keeping an eye on tyre wear patterns can also be a helpful early warning system. If one side of the tyre wears out faster than the other, it could be a sign that suspension components, like the control arms or their bushings, need some attention.

All up, control arms are a key player in what makes the Lexus IS such a comfortable and capable drive. Taking care of these parts as part of your regular servicing routine helps keep the car handling true to its design and ensures your driving experience remains smooth and safe for years to come.
