Which of these indicates a front cradle out of alignment?

The indication of a front cradle being out of alignment is best described by the thrust angle measurement. A thrust angle of 0.1 degrees suggests that there is a slight misalignment of the rear axle, which can affect the alignment of the front cradle as well. Such a scenario can lead to handling issues, as the front wheels may not be pointing in the same direction as the rear wheels, causing the vehicle to pull to one side while driving. This underscores the importance of proper alignment in the overall performance and safety of the vehicle.

In contrast, variations in SAI/KPI or discrepancies in camber readings could pertain to issues with specific suspension components rather than a direct indication of the cradle's alignment. While camber readings showing one side positive and the other negative might suggest an imbalance, they do not specifically indicate that the cradle itself is misaligned like the thrust angle does. Therefore, the thrust angle is a more relevant metric for determining cradle alignment issues.
