If the flat 'locking' nuts are done up as tight as they should then the cones shouldn't loosen at all. They might bed in but the lock washers need to tighten very tight to lock them otherwise the cone will loosen just a fraction as it moves out to the lockwasher. This always gives the impression that it is tight as the washer now seems tight but the cones are loose. Hope that may make sense, it does in my head
I had a similar issue with the rear XT hub that is used on the front of my Pugs. Took me a few goes to get it spot on. On one ride at Forth Fat, the first after I put it back together it actually tightened. I didn't know, just thought I was on one of those bad days where your legs feel dead and you have trouble riding on the flat, no oomph in the legs, only to find when I hosed it at the end of the day that the wheel wouldn't turn :roll:
I had good legs the next day!
