The steering knuckle and tie rod end are key components of a vehicle's steering system, responsible for precise control and driving stability.

The tie rod end is used to transfer the movements of the steering wheel to the vehicle's wheels, allowing them to turn and control the direction of travel. It is a part of the steering system that connects the steering rod to the wheel hub, so that the rotational movement of the steering wheel translates into the actual movement of the wheels in the appropriate direction. The tie rod end contains a ball joint that allows for flexible movement, adapting to road irregularities and changes in the angle of the wheels. This ensures smooth turning and stable vehicle handling, which is essential for safe and comfortable driving.

A joint (usually a ball joint) is used to allow smooth and flexible movement between the steering or suspension elements in a vehicle. Its main function is to provide free movement in various planes, which allows the wheels to adapt to uneven terrain and make turns. A ball joint allows rigid elements such as the steering rod and suspension to be connected, while providing them with mobility, which is crucial for stability and steering precision. Thanks to the joint, the wheels can move vertically (in response to road irregularities) and horizontally (when turning), ensuring safety and driving comfort.

Regular inspection and replacement of these components is essential for vehicle safety, as wear in joints or tie rod ends can lead to play in the steering system, affecting steering precision and driving stability.
