Then again again ^^ I've just read that Shimano freehubs are specific to each hub. I thought they were generically interchangeable within the limits of speeds and OLD, just getting better bearings, ratchets and metallurgy as you paid more. Shop (who I actually trust) have told me mine is a poor design of freehub (which I suppose explains how it wore out quicker than chain and cassette) so that seems pointless. Ok, new hub and wheelbuild it is or else new factory wheel.
