For my friend's bike i bought a whole new hub but not for that reason. I did it because a new Tiagra hub from the UK was cheaper than just the same freehub from the US and I got the all-important matching drive side cone with it. And no need to rebuild the whole wheel.
If he had some odd hub with no replacement freehubs available a whole new hub would be best. But Shimano hubs,
in my experience, use one of two different freehubs (excluding Dura Ace and XTR stuff). The OP just needs to remove his current freehub to figure out which back end it has and then order the matching part, or as I did, a current hub using the same freehub.
