The problem seems to come back at least as bad, if not worse each time...wandering crank arm...? Sounds pretty logical. I don't understand why the guy I've been dealing with most doesn't seem to think that would do it?
Mine would quiet down with a re-tightening of the left crank arm, then get noisy again after 10-15 miles of riding. Only after I did a bit of reading and discussed the problem with some mechanically-inclined friends did I try the cassette fix.
The detail of my cassette fix (it's Campagnolo splined, FYI):
1. Removed lockring and cogs.
2. Lightly greased splines on the hub with Park grease.
3. Cleaned cogs and screw threads on hub and lockring.
4. Reinstalled cogs.
5. Lightly coated lockring with Shimano anti-seize grease and tightened to spec with torque wrench.
Voila! No more noise!
Campag cassettes tend to be a bit more picky and noisy if not lubed on the splines, from my experience. Never had the same probs on my Shimano setups.
Hope this helps!
