Which issue would likely lead to steering wheel bind when turning?

Excessive worm bearing preload can lead to steering wheel bind when turning because it creates too much resistance in the steering mechanism. The worm gear and the bearing work together to allow smooth movement of the steering wheel. When the preload is too high, it compresses the bearings excessively, which can prevent free rotation and cause the steering wheel to feel stiff or bind during turns. This binding sensation is often experienced by the driver, making it difficult to maneuver the vehicle.

In contrast, while incorrect ball joint specifications or high pressure in the steering fluid can have their own effects on the steering system, they are less directly associated with the specific issue of steering bind during turns. Loose steering column bolts may lead to other concerns, such as misalignment or play in the steering feel, but they wouldn't cause binding in the same way that excessive preload would. Understanding the precise mechanics of the steering system helps to identify why excessive worm bearing preload is the primary cause of steering wheel bind in this scenario.
