as someone who has a hub in which has sideways play I can advocate taking the hub apart, cleaning it all up, repacking the bearings and greasing that baby up!
for the long term good of your wheel it is worth it, though if you have warranty just get a new set as your bearing racers may be knackered and it is frustrating if you are fiddling round tightening or loosening your hub cones every time you take your wheel off as that is what happened to me.
