persistent loosening cone on rear hub
Here's a new one to me - my rear hub keeps loosening. I get the cones as tightened as possible without impeding rotation, crank down on the nut, put it on the bike, and everything's fine (a little side-to-side play, but nothing outrageous). Yet the next time I check it, there's way more wobbliness than I like. Today, after adjusting and tightening it last night, I did a tiny little skip and heard a noise, and lo and behold, it's wobbly again.
Hub is a Surly. I have another set of surlys that I don't think I've ever had to adjust. It's been in service for around a year, and I've only noticed the looseness in the past month or two. The wheel joined me on a January trip across the hood of a car, but seemed fine thereafter (wasn't even out of true). Any thoughts, junior detectives?

Yep, sealed bearing. I'll try some loctite on the nut, thanks.
Any conjecture on why it is getting loose? I've heard of people having surly hubs tighten up on them, but not loosening (I guess I'd choose loosening if it has to be one or the other).

For serious? Have I just been lucky with my other wheelsets, then? Hmm...
Do locknuts typically move in one direction only? Like, if I moved the cog to the other side, would it be more prone to tighten up and eat my bearings?

one of the reasons why surly hubs are flawed.

I thought pretty much all Taiwanese track hubs used a straight axle, though. And as I said, I haven't had any problems of this type with my other set of surlys. Although, yeah, there's some undeniable oversights in the design.
Well... hopefully loctite will do the job.

have you tried counter tightening the crap out of the cone/locknut on one side before doing the adjustment?
