When diagnosing steering issues, which component is most likely to cause a clunking noise when turning the steering wheel?

The presence of a clunking noise when turning the steering wheel is typically associated with worn or damaged ball joints. Ball joints serve as the pivot point between the suspension and the wheel, allowing for the necessary movement when steering and going over bumps. When these components deteriorate or become loose, they can create play in the steering system, leading to the characteristic clunking sound as the suspension moves.

This noise often becomes more pronounced during maneuvers that stress the suspension, such as tight turns or during braking when weight shifts. Ball joints are critical for maintaining proper alignment and stability of the vehicle, and failure to address issues with them can lead to more serious handling problems and safety concerns.

While power steering fluid and drive belt tension can affect steering performance, they do not typically cause a clunking noise. Similarly, while tie rod ends are also essential components of the steering system, they are more likely to produce a squeaking or grinding noise when worn rather than a clunking sound. Therefore, when diagnosing clunking noises specifically linked to steering movements, ball joints are the most probable source of the problem.
