What is the correct action when the cotter pin slot does not align with the hole after torquing?

When the cotter pin slot does not align with the hole after torquing, the proper action is to tighten slightly to achieve alignment. This approach is important because the cotter pin serves a critical safety function in a suspension and steering system. It locks the nut in place, preventing it from loosening due to vibration or dynamic loads.

Slightly tightening the nut can help line up the slot with the hole, allowing the cotter pin to be properly inserted. This ensures that the assembly remains secure and functions safely. Proper alignment of the cotter pin is essential for maintaining the integrity of the system and preventing potential failure while driving.

Leaving it misaligned would risk the nut coming loose, which could lead to severe handling issues or complete failure of the suspension or steering components. Loosening the nut below torque would not be advisable, as it could also compromise the tightness needed for safety. Using a different size cotter pin is not a practical solution either, as the pin size must correspond to the design specifications to ensure a secure fit.
