Otherwise, one would assume that the pickleforks on all B737 NG aircraft will eventually crack when reaching say, 35,000 to 45,000 cycles, unless some other close-out action is taken.
maybe not in situ, as the stress relieving process involves drawing a mandrel through an interference-fit sleeve, thus work hardening the perimeter of the bolt hole. I don’t know the ramifications of revisiting a component that has already suffered the tribulations of line service let alone the utility of not just replacing the component, since removal would seem to be required for any retrospective fatigue relief anyway.
