Control arms contribute a lot to your Subaru’s suspension system. Also called “A-arms,” they attach the wheels to the suspension.
Common Symptoms of a Bad Subaru Control Arm
A Subaru control arm usually needs replacement because of extensive wear on its bushing or ball joint. The control arm itself can get damaged during collisions.
If you encounter one or more of the following symptoms, you may have a bad or failing Subaru control arm that requires replacement:
When you drive your Subaru over bumpy terrain, you may hear a clunking sound coming from the suspension. You may also hear banging noises when you’re flooring the brake or gas pedal. These sounds can come from Subaru control arms with worn ball joints and bushings that cannot dampen vibrations.
Pulling to One Side
If your Subaru recently hit an object or vehicle, it may give off the sensation of getting pulled to one side when you drive it. The force of the collision may have bent the control arm and misaligned the Subaru’s suspension system. Alternatively, the ball joint or bushing of the control arm is too old to operate correctly, causing the same problem.
Uneven Tire Wear
Control arms help determine how your Subaru distributes its weight across its suspension. A bad control arm puts more weight on the wheel attached to it, causing the tire to wear out faster.
Erratic Steering Response
Anything that affects the control arm also affects the steering knuckle connected to it. A Subaru control arm with worn ball joints or bushings will cause the knuckle to move erratically. This malfunction causes the steering wheel to shimmy and affects the Subaru’s handling.
What is the Cost of a Replacement Subaru Control Arm?
A replacement Subaru control arm can cost anywhere between $20 and $460. Its price tag varies according to the product’s brand, the number of control arms in the set, and the other parts that come with the control arms. You can get a control arm individually or in sets of two, four, six, or 10.
Selecting the Best Subaru Control Arm
Keep the following parameters in mind when searching for a replacement Subaru control arm:
Always ensure the compatibility of a replacement Subaru control arm with your vehicle. Fit may vary per model. For instance, you can’t install a Subaru Forester control arm in a Subaru Impreza’s suspension system and vice versa.
To find a specific part, enter your Subaru’s year and model in our website’s filter bar. Doing so lets you find a 2010 Subaru Forester control arm guaranteed to fit your vehicle.
If a control arm shows signs of heavy wear or damage, replace it and its partner at the same time. This saves you the trouble of having to replace the opposite control arm when it eventually fails.
Subaru vehicles feature the 4-wheel independent suspension system. Their front and rear suspensions both have control arms, and there are enough differences between the front control arm and the rear control arm to prevent interchangeability. Get replacement control arms for the correct location.
