Ok - I'll remove, clean and regrease the freehub, and reasssemble, with any required rr der adjustment (I didn't regrease the first time - everything seemed to fit well enough)
I do not have a torque wrench, The campy lockring says torque to 50Nm. I guess that's a "firm press" with a 12 inch cresent wrench and a chain whip. My friend says the tire stores torque the lug nuts to 80Nm.
BTW, is there a requirement to lube the freehub in any way? everything is sealed.
