Stripping a hub thread?

If I did strip it, is it more likely that the thread on the hub is buggered or that on the lockring? I was told that it'll most likely be the hub but surely the lockrings are manufactured to be weaker in the case of this happening as they're easier to replace.

If the sprocket is steel, the hub's threads will more likely be stripped.

I'd be tempted to scrub the threads down with wd40, dry, regrease (use anti-seize) then tighten the sprocket on again as far as it will go and see if that makes a difference. You might just have a build up of shit on the sprocket thread.
