Cones coming loose

Read this post. It gives tips on how to lock the nuts together.

Don't bother with thread lock. The whole thing will be greasy as hell and the threadlock won't cure.

Too late!

I degreased the thread at the appropriate place first though.



I probably gave a bit of a crap explanation in my OP:

I am not aware of the locknuts themselves being loose when I take out the QR (they still take a cone wrench and a 17mm spanner to undo) - but I keep developing a wheel wobble (from the hub, of the type you get when your cones are too loose) every 100 miles. Thinking now, could it be something else?

Bear in mind that I carry quite a lot of heavy stuff in panniers and have to use UK-standard roads....

So the cone and locknut are still tight together when you notice the problem? Bent axle? Worn cups/cones?

Yes, tight together when I start to re-adjust them.

Only 1700 miles.

Axle is visually straight.
Cups and cones appear smooth when degreased.

Obviously over time the cones can come loose. I would've thought this wouldn't be too uncommon for people who carry heavy luggage around all the time and someone would have a wee secret tip for dealing with it?

I had one hub that I decided to change from QR to solid axle. I do know what I am doing with cup/cone bearings and locknuts but this was a complete fooking disaster. Tighten as I might, the cone and locknut would unwind in a few tens of metres of riding. Changed it back to QR and all was well.
Was never able to isolate the cause but it wasnt heavy luggage. My suspicions were a very slight bend in the axle, or some mismatch between cones from one set and cups from another.
