The control arm assembly keeps the wheels in line with the car’s body to control the motion of the wheels. They are a vital piece of your vehicle’s suspension system as they absorb the bumps and imperfections of the road. The control arm assembly joins the car’s suspension to the structure of the car. The assembly is connected via ball joints to the wheels and to the frame by bushings. This setup is normally found in the front of vehicles, as very few cars have these in the rear.
Over time, the control arm assembly can become worn or bent. These assemblies normally wear out between 90,000 and 100,000 miles. They can wear out faster if you go over a large pothole or are involved in a car accident. Various parts of the assembly may wear out as well, such as the bushings or ball joints.
