This steering rod end connects the steering linkage to the axle assembly, translating rotational input from the steering gear into linear motion that turns the wheels. It is the right-side component, mounted on the axle end of the drag link. A worn rod end introduces play in the steering system, causing imprecise directional control and uneven tire wear. The ball joint within the housing is pre-loaded at the factory; re-torque the lock nut to specification during installation to maintain proper articulation without excess free play.
