Steering Knuckles & Spindles

Through pivots known as "ball joints," the top and bottom arms of the steering knuckle are connected to the suspension system. The knuckle may swivel left or right thanks to the ball joints. Additionally, they maintain the knuckle's vertical posture. Another component of the steering knuckle is a lateral arm that joins to a tie rod.

Depending on which way the steering wheel is moved, the tie rod either pushes the lateral arm outward or pulls it inward while you steer. A vehicle has tie rods on both sides. The opposite lateral arm is drawn inward simultaneously with the lateral arm on one side being pushed outward. This causes the front wheels and knuckles to rotate together.
