I was triggered by your initial question. The entire reason recent Fox CSU's creak is because in 2015 when they released the new 36 they made the crown 10mm lower at the steerer tube to minimize ATC height for the new taller 27.5 and 29" forks. The old 26" 36 forks had a super-tall bombproof crown, and there are still 2007 36 forks on dirt jump bikes around the world that don't creak, whereas my brand new 2020 36 creaked after three rides. All the while 10mm of axle to crown height doesn't really affect ride quality- just run one...
