What is a steering tie rod and tie rod end?

Steering tie rods and tie rod ends are part of the steering rack system. As the wheel moves up and down over uneven road surfaces the articulated joint in the rod allows that movement so that the rod does not become damaged.

The tie rod end is fitted to the end of the tie rod. The tie rod end provides 2 main functions. It provides adjustment to the wheel being steered so that its track or direction of the wheel can be aligned. The ball joint end of the tie rod end provide articulation so when the wheel is being steered it can move accordingly.

These parts are available in different sets as follows:

• Single tie rod

• Single tie rod end

• Single tie rod and tie end kit

• Single tie rod and tie end kit with boot kit
