An adjustable suspension arm is one of the most important parts of your car. Without a robust arm to act as support, the weight of your vehicle will, over time, cause permanent damage to your suspension system. That’s why it is so important to monitor the condition of your suspension arm to avoid costly repairs. A typical indicator of a faulty suspension arm, otherwise known as a control arm, is unnatural handling on the road. Drivers may notice that a car veers or leans in a certain direction when steering, and this almost always means that the suspension arm is not controlling the weight of the vehicle properly and needs to be replaced.
