The inner tie rod end used on​ rack-and-pinion steering units is also called a​ ________.

The inner tie rod end in rack-and-pinion steering systems is referred to as a ball socket assembly. This component connects the inner tie rod to the steering rack. The design allows for a pivot point that enables the tie rod to transmit the steering input from the steering wheel to the wheels of the vehicle while maintaining the necessary level of flexibility.

This functionality is critical because it accommodates the movement required when steering the vehicle while also managing the stresses and forces encountered during driving. The ball and socket design allows for smooth motion and helps absorb shocks, enhancing the overall steering response and comfort for the driver.

In contrast, the other terms do not accurately describe this component. The connecting link typically refers to different types of linkage in suspension or steering systems, often associated with maintaining alignment. A rubber-bonded socket is not a widely recognized term in automotive terminology, and relay rods typically pertain to linkage systems rather than tie rod assemblies. Thus, recognizing the specific term "ball socket assembly" helps clarify its function and purpose in the steering mechanism.
