Loose? the whole thing's a deathtrap now! Before buying penetrating oil, is it OK to try my WD40 first? (cpg please post the American equivalent if he's unfamiliar with Hertfordshire postcodes

I expect the bearings to be under the large black bit that forms the stem hinge. Take care when removing it, lots of small ball bearings will fall out and roll away never to be seen again.
Before I risk that calamity, can you say how that might help me secure the lockring? When I tighten it fully the steerer doesn't wobble at all, so doesn't the solution lie above the ball bearing regions? I still can't work out how it managed to loosen when I thought I had it jammed by that screw. I did mark the bits but I'm now wondering if it rotated itself by exactly 360°, or more likely 720°. However, I'm pretty sure the screw would have been dislodged when the gaps passed it.
