Control Arms on the 2018 Subaru Impreza: What They Do and How to Look After Them

The 2018 Subaru Impreza, like many modern vehicles, uses control arms as a critical component of its suspension system. These parts play a huge role in ensuring the car handles well, offers a smooth ride, and remains safe on the road. Control arms are definitely present in the 2018 Impreza, and understanding what they do and how to maintain them can really help keep the car in top shape.

Control arms are essentially the link between the vehicle's chassis and the wheels. They connect the suspension to the frame and allow for controlled movement of the wheels. This is crucial because the wheels don't just move up and down, they also need to pivot and adjust to road conditions while maintaining alignment and stability. On the 2018 Subaru Impreza, the front suspension features a MacPherson strut setup, with lower control arms playing a key role in managing the wheel's movement. At the rear, the Impreza often uses a multi-link suspension, which also incorporates control arms as part of a more complex assembly to enhance handling and comfort.

The main purpose of control arms is to help absorb the shocks from bumps, potholes and other road imperfections, all while keeping your tyres firmly in contact with the road. This balance is vital not only for comfort but for safety. If the control arms didn't perform this job, the wheels could wobble or become misaligned, which could lead to uneven tyre wear, poor handling, and even dangerous driving conditions.

Each control arm typically has bushings and ball joints that allow it to move flexibly but precisely. These rubber or polyurethane bushings cushion the joins between the arm and the vehicle's frame or the wheel hub, reducing vibrations and noise. The ball joints act as pivot points, giving the wheels the freedom to steer and articulate up and down over the suspension travel.

Given the importance of control arms in the 2018 Subaru Impreza's suspension system, maintaining them is an important part of the vehicle's servicing schedule. Over time, these components can wear out or become damaged due to factors like harsh road conditions, corrosion, or simply the age and mileage of the vehicle. Worn control arms, bushings or ball joints can result in a range of symptoms such as clunking noises when going over bumps, steering wander, uneven tyre wear, or a generally rough ride.

When a control arm shows signs of wear, replacement is usually the best option. Because they are crucial to the stability of the vehicle, it is not recommended to delay repairs. Most auto workshops will perform a thorough suspension inspection during routine services, so it's a good practice to ask your mechanic to check the control arms regularly. This way any issues can be caught early before they lead to more costly repairs or safety hazards.

Replacing control arms on a 2018 Subaru Impreza typically involves removing the old arm assembly including worn bushings and ball joints and fitting a new one that meets OEM specifications. It's important the job is done carefully to maintain correct wheel alignment and suspension geometry. After fitting, a wheel alignment check and adjustment will almost always be necessary to ensure the car tracks straight and the tyres wear evenly.

Aside from replacement, some preventative care can extend the life of control arms. Regular visual inspections for rust or damage, along with ensuring the vehicle's suspension components are kept clean and free of excessive dirt build-up, can be helpful. Avoiding prolonged exposure to corrosive materials such as road salt can also keep the arms in good condition for longer.

For Subaru Impreza owners who live in areas with rough roads or who regularly drive on gravel, checking the suspension and control arms more frequently makes sense. These conditions can accelerate wear and tear, so staying on top of maintenance helps avoid unexpected surprises and keeps the ride feeling smooth and safe.

All up, the control arms in a 2018 Subaru Impreza are vital players in the car's suspension system. They work behind the scenes to ensure every drive is comfortable, stable and safe. Paying attention to their condition and getting them serviced or replaced as needed is a smart move for any Impreza driver wanting to keep their vehicle running well for the long haul.
