Parts for your 2012 Subaru Outback-Control arms

Understanding Control Arms on the 2012 Subaru Outback

The 2012 Subaru Outback is well-known for its rugged reliability and comfortable ride, and a big part of that comes from its suspension system. Among the components that make up this system, control arms play a crucial role. So, is the 2012 Subaru Outback fitted with control arms? Yes, it certainly is. Control arms are essential parts of the Outback's front and rear suspension, helping provide that balance between smooth handling and off-road capability the model is famous for.

Control arms, sometimes called A-arms or wishbones, are metal components that connect the vehicle's suspension to the chassis. They allow the wheels to move up and down while keeping them in proper alignment with the road surface. On the 2012 Subaru Outback, the front suspension uses lower control arms paired with struts and stabiliser bars. The rear suspension also includes control arms, though the exact configuration differs slightly due to the multi-link rear suspension design Subaru employs.

The main purpose of control arms is to maintain wheel positioning and enable smooth suspension movement. When driving, roads can be rough, with bumps and dips that would otherwise make for a jarring, unstable experience. Control arms let the wheels react to these road imperfections by pivoting at the chassis connection point while holding the wheels steady in their designated path. This means better control for the driver, improved safety, and a more pleasant ride for all passengers.

Another critical role of control arms is their influence on wheel alignment. Proper alignment ensures tyres wear evenly and the car handles predictably, especially at higher speeds or over uneven terrain - something Subaru Outback owners will appreciate when taking their car off the beaten track. If control arms become worn or damaged, alignment can suffer, leading to uneven tyre wear, poor handling, and even increased fuel consumption due to added rolling resistance.

Because control arms are constantly under strain from road impacts, it's important to keep an eye on their condition. The components most prone to wear on a control arm are the bushings and ball joints. Bushings are rubber or polyurethane inserts that absorb vibration and allow flexible movement between the arm and the chassis. Ball joints connect the control arm to the steering knuckle or wheel hub, providing a swivel point for the wheel to turn and move up and down.

Over time, bushings can crack, harden or deteriorate, especially with exposure to harsh weather and road salt, both common in Australian conditions. Ball joints can wear out and become loose or develop play, which impacts steering feel and vehicle stability. Symptoms of worn control arms or related components include knocking or clunking noises over bumps, uneven tyre wear, a pulling sensation during driving, or excessive vibration through the steering wheel.

When it comes to maintenance, checking control arms is usually part of routine suspension inspections during servicing. A qualified mechanic will visually inspect the control arms, the condition of the bushings, the ball joints, and any associated hardware like bolts or stabiliser links. If any signs of wear or damage are spotted, replacement is generally recommended. Because control arms are integral to handling and safety, it's not a part to delay replacing.

Replacing a control arm on a Subaru Outback typically involves removing the wheel, disconnecting the ball joint from the steering knuckle, detaching the arm from the chassis mounts, and installing a new arm with fresh bushings and ball joints if necessary. It's a straightforward job for professionals but requires specialised tools and correct torque settings to ensure safety and performance.

One important thing to keep in mind after replacing control arms is the need for a wheel alignment. Since the control arms govern the positioning of the wheels, having the car properly aligned post-installation will help ensure tyre longevity and provide the precise handling expected from a Subaru Outback.

Good servicing habits can extend the life of control arms. Regularly washing the undercarriage, especially after exposure to mud or road salt, helps prevent corrosion. Avoiding potholes and harsh driving potholes or rough terrain can reduce premature wear, although the Outback is designed to handle Aussie country roads better than most.

Overall, control arms are a vital part of the 2012 Subaru Outback's suspension setup, contributing significantly to ride comfort, vehicle control, and safety. Staying on top of their maintenance not only keeps the Outback driving smoothly but protects the investment in your vehicle over the long haul. Whether cruising city streets or exploring remote tracks, well-maintained control arms help this iconic Aussie favourite keep performing at its best.
