Which technician is correct regarding steering gear sector shaft preload settings?

The correct answer emphasizes that both technicians are providing valid information regarding steering gear sector shaft preload settings.

One crucial aspect of setting the sector shaft preload is ensuring that the steering wheel is centered. When the steering wheel is positioned at center, it allows for the most accurate adjustment of the sector shaft preload, which is essential for optimal steering performance. Centering the steering wheel ensures that both the left and right turns will have equal travel and responsiveness, preventing uneven wear or handling issues.

Additionally, disconnecting the drag link is an important step during this process. By removing the drag link, the technician can adjust the sector shaft preload without any resistance or interference from the steering linkage. This allows for a more precise setting and eliminates the potential for false readings or misadjustments caused by connected components.

Both of these practices are standard procedures to achieve the correct preload settings on the steering gear, leading to a well-functioning steering system.
