Understanding the Control Arms on the 2017 Subaru Forester

The 2017 Subaru Forester, known for its reliability and all-terrain capability, relies heavily on well-engineered suspension components to deliver a comfortable and controlled ride. One of the key parts in this setup is the control arm. Control arms play a vital role in how the Forester handles the road and absorbs bumps along the way. For anyone interested in maintaining their Forester or simply keen to know what's going on under the car, understanding control arms and their maintenance can be a real asset.

Control arms, also sometimes called A-arms, are a fundamental component of modern independent suspension systems. On the 2017 Forester, control arms connect the vehicle's frame or subframe to the wheel hub, keeping the wheels aligned and allowing them to move up and down independently. This independence is crucial for smooth steering and handling, especially when tackling rugged terrain or sharp turns.

The Forester's suspension setup features lower control arms at the front and a combination of control arms at the rear, depending on the variant and drivetrain. These arms are typically made from stamped steel or forged aluminium for strength and durability. The use of bushings at the mounting points helps absorb shocks and vibrations, reducing wear and tear on the chassis and providing a quieter ride.

One of the main purposes of the control arms is to control the motion of the wheels relative to the vehicle body. By doing so, control arms ensure that the wheels maintain proper camber and caster angles during driving. This helps maximise tyre contact with the road, improving traction, steering response and overall stability.

For a practical perspective, think about hitting a pothole or driving over uneven ground. The control arms guide the wheel up and down smoothly without forcing the whole vehicle to bounce excessively. This action enhances comfort inside the cabin while protecting other components from damage.

Given their critical role, control arms are an important consideration during regular servicing or repairs of a 2017 Subaru Forester. Like many suspension parts, control arms face constant stress and can wear out, especially if the vehicle frequently tackles rough or off-road conditions. Common issues can include worn-out bushings, bent arms from impacts, or loose ball joints.

Maintenance for control arms mainly involves inspection and, where necessary, timely replacement. During a scheduled service or if you notice symptoms such as clunking noises over bumps, uneven tyre wear, or poor steering feel, a mechanic should check the control arms. The bushings should be looked at closely for cracks or excessive movement, while the arm itself should be inspected for any signs of damage or corrosion.

Replacing control arms on the 2017 Forester isn't uncommon as the vehicle accumulates kilometres. While bushings can sometimes be replaced separately if only worn, it is often more straightforward and safer to replace the entire arm, especially if ball joints are integrated. Choosing high-quality replacement parts that meet Subaru's specifications is important to maintain the original handling characteristics and durability.

Another factor to consider during and after control arm replacement is wheel alignment. Since control arms play a key role in wheel positioning, any changes can affect alignment angles. This makes it essential to have a professional alignment check and adjustment post-installation to ensure the Forester remains stable, steers accurately and tyres wear evenly.

In everyday terms, looking after the control arms on a Forester means smoother trips, better control on and off-road, and less risk of costly suspension damage later on. If the vehicle is mostly used on paved roads, the control arms may last longer, but if there's regular exposure to rough tracks or harsh conditions, more frequent inspections are recommended.

Ultimately, the control arms on a 2017 Subaru Forester are a quiet but crucial part of what makes the SUV so capable and enjoyable to drive. Whether servicing the vehicle yourself or taking it to a trusted mechanic, keeping an eye on these components helps ensure the Forester continues to perform at its best for years to come.
