Control Arms on the 2007 Subaru Legacy: What They Do and How to Look After Them

The 2007 Subaru Legacy is a solid choice for those looking for a reliable mid-sized sedan or wagon with a bit of all-wheel-drive flair. One important part of the suspension system that helps keep the car handling well and riding smoothly is the control arm. For anyone curious about whether their Legacy uses control arms, or how to maintain them, it's good to understand their purpose and what to watch for over time.

Firstly, yes, the 2007 Subaru Legacy does use control arms. Control arms are key components in the suspension setup, linking the wheel hub to the vehicle's frame. They allow the wheels to move up and down over bumps while keeping them correctly positioned relative to the rest of the car. The Legacy's front suspension typically features lower control arms that play a crucial role in this. Depending on the model and trim level, there may also be upper control arms or variants like strut-type setups, but in general, control arms are an essential part of the Legacy's suspension.

So, what exactly is a control arm? Think of it as a sort of lever or arm that connects the suspension to the chassis, usually with bushings and ball joints at either end. These parts enable the wheel to move in a controlled way during driving, ensuring the tyres stay in contact with the road surface for grip and control. Without a properly functioning control arm, steering would feel loose or imprecise, the ride could become rough, and tyre wear might increase significantly.

Control arms contribute to your car's stability and comfort by managing the angles and movement of the suspension. On the 2007 Subaru Legacy, the front lower control arms are commonly made of stamped steel or sometimes aluminium, designed to be strong yet lightweight. These arms pivot on bushings that absorb vibrations and shocks, while ball joints at the wheel end enable that necessary steering and suspension articulation. If these bushings or ball joints wear out, the control arm's effectiveness drops, leading to handling issues.

Maintenance of control arms usually comes down to checking these bushes and ball joints for wear and damage. In everyday driving, bushings can degrade due to heat, exposure to dirt, oils and other road contaminants, while ball joints may fail because of lack of lubrication or corrosion over time. For a Subaru Legacy that's clocked many kilometres, it's not unusual to see some wear, especially if driven on rough roads or if the vehicle has been through heavy use.

When servicing the control arms on the 2007 Legacy, mechanics generally look for signs like clunking noises coming from the front suspension, uneven or rapid tyre wear, steering wheel vibration, or a loose or unstable feeling when driving. These symptoms often hint that the control arm bushings or ball joints might be wearing out and need attention.

Replacing control arms, or their components, is a relatively straightforward job but does require the right know-how and tools to ensure everything is aligned properly afterward. It is very important to have a wheel alignment performed after installing new control arms or bushings to maintain proper suspension geometry. Without correct alignment, the vehicle will not handle well, and tyres will wear unevenly.

Many drivers choose to replace the entire control arm assembly rather than just the bushings or ball joints. This approach can often be more cost-effective in the long run because the arms themselves can get bent or weakened over time, especially if involved in minor impacts or rough driving conditions. Brand new control arms come complete with fresh, factory-fitted bushings and ball joints.

For those keen on DIY, it's crucial to follow vehicle-specific repair manuals or guides, as the 2007 Subaru Legacy's suspension parts have particular torque specifications and installation procedures to ensure safety and reliability. However, for the average driver, having a qualified mechanic check and replace control arms during regular suspension servicing is a smart move.

Routine checks during servicing intervals should include a visual inspection of the control arms and related suspension components. In addition to the obvious signs like cracks or splits in bushings and excessive ball joint play, it's essential to check for rust or corrosion, which can weaken the arms over time. Keeping these parts in good condition helps maintain the Legacy's smooth ride and responsive handling.

Regular maintenance of control arms on a 2007 Subaru Legacy helps extend the life of the suspension system and ensures that the vehicle remains safe and comfortable to drive. Ignoring worn control arms can lead to more serious suspension failure or costly repairs down the line, so it pays to stay ahead by inspecting these parts regularly.

In essence, control arms are a critical but often overlooked component that keeps the 2007 Subaru Legacy's wheels moving as they should. Proper care and timely replacement will help the vehicle maintain its renowned stability and comfort throughout its life on the road.
