Both ball joints and tie rod ends are each a part of the front suspension and steering system of your car and are located between the front wheels. The steering system spans the entire length between the front wheels, connecting the two wheels together, while the suspension system is contained just inside each front wheel.
Control arms, sometimes called “A arms,” are the core of your front suspension system. In simple terms, control arms are the link that connects your front wheels to your car. One end connects to the wheel assembly and the other end connects to the framework of your car.
