The effing bushing was missing!
It was Nut-Washer-Swaybar... maybe it was the 95* heat or 70% humidity but I was flabbergasted. I redid the endlink bushings a year or two ago (Moog brand) and know I gave them bushings all around. And it wasn’t like there was a gap where the missing bushing should have been.
I did go ahead and throw a spare (no, wasn’t the one that should have been there to begin with) in there so all is currently well.. albeit confusing.
I did get a replacement set of endlinks from Rock Auto when they were on sale in case the Suspension Gnomes come back and remove them again.
