As above, put the cv joint back in the hub and you'll see why. 
Sure Tom, you go ahead and spend £60 on a driveshaft / £15 on a balljoint when you could put a £4 / £1 boot on, small wonder your project costs always spiral out of control. Yes it's a small risk that the damage has already been done, but it's only an hour or so to do the job, even if you're not too experienced with the spanners. Is your time worth £15 an hour, because mine isn't.
