Install Top-Quality Control Arms for a Smoother Ride
Wheels on most vehicles have one or two A-arms on the front and rear suspension. These arms typically feature bushings on the frame side and a ball joint on the wheel side of the car. With both components, your wheels can flex and control their movement based on road conditions and steering.
A-arm bushings cushion your suspension system, controlling noise and vibration. You also get a softer ride over bumps, thanks to these suspension parts. The control arm bushings stay stiff and return to their original shape and position as they flex and move. Meanwhile, the ball joint of your car’s A-arm connects and holds your Subaru’s front suspension together. The joint allows limited motion in all directions.
Cars can have upper control arms, lower A-arms, or both. Most front-wheel-drive vehicles use lower control arms, while trucks and SUVs use both upper and lower arms. Trucks and SUVs have two pairs of lower and upper arms each, also known as a double-wishbone suspension. These arms can be made from stamped steel, cast iron, or cast aluminum.

Most A-arms wear out every 90,000 to 100,000 miles. These components are not immune to wear and tear. Once these suspension parts get damaged, you might experience unstable steering, uneven tire wear, or hear popping sounds as you drive. A worn control arm can affect your Subaru’s overall performance as well. Replacing your old suspension arms will help fix any of the issues above.

What is a control arm on a car?
A control arm is a critical component of any vehicle suspension system. It is a direct connection between the frame and front wheel assemblies, allowing you to steer your ride in the direction you want. You can also adjust your suspension arms for better handling stability or if you need to house bigger tires for your car.
What are the typical bad control arm symptoms?
Control arms can still deteriorate and get damaged over time. For instance, you may hear a clunking noise around the wheel or experience vibrations as you drive through uneven surfaces. Your vehicle may also pull to the left or right while maneuvering on a flat road. If your car shows any of these symptoms, you might need to replace your suspension arms.
Can I drive with a bad suspension arm?
We do not recommend driving with a damaged control arm since it will make your car unsafe and unstable on the road. You risk losing control of your car while in transit or having your wheels fall off as you drive. Make sure that your control arms are stable and secure to have safer drives.
Can I replace just one control arm?
Control arms should always be replaced in pairs. If the left component is already showing symptoms of wear or its bushings are torn, the right arm will need to overcompensate, making it only a matter of time before it eventually breaks down as well. Replacing both components at the same time also minimizes the hassle of one breaking after having replaced the other.
How many suspension arms are in a car?
Most vehicle suspension setups have either two or four control arms. Modern cars only have suspension arms in their front wheel suspension, while heavy-duty vehicles like trucks and SUVs have additional control arms on their rear axles for additional support and stability. These can also be adjustable according to the driver’s preference.
