All i know is that if i loosen up the axle locknut on the drive side a little bit, this symptom will cease. Ofcourse the locknut i am talking about is supposed to be on the NDS if i understand you correctly. Another important point i was trying to figure out was if tightening this assembly should be done exclusively by finger force or with a more powerful wrench tool (would tell me something about the NM forces required to get it right) My other 26" Trek fuel bike has the same problem, and this has not ceased since it was upgraded a year or two ago from a now closed down bike shop.

These need to be more than finger tight otherwise they will loosen on their own. You need "cone wrenches" to do this job. They aren't expensive. The idea is that the cone and locknut jam eachother to keep proper bearing adjustment and not tighten or loosen on their own. The cone adjustment article should explain it better.
