What Does A Control Arm Do On A Vehicle? Simply put, it helps a driver to steer a car while also allowing up and down movement of the suspension for your car to remain in full contact with the road. The Control Arms and Ball Joints move up and down with the spring when a car hits a pothole or dip in the road. This allows the Tires to maintain contact with the road and remain in control. A few Signs of Bad Control Arms are unstable steering, Popping Noise While Driving from the Ball Joint, or Uneven Tire Wear. As Control Arm Bushing wear, this can force the vehicle out of Tire Alignment, causing wear on the outer or inner edges of the Tire. If your vehicle is having any of these symptoms, check out an Auto Mechanic Shop soon.
