My front wheel has some play which drives me crazy I have a mountain bike and it's front wheel has some play in it. I have replaced the bearings and the whole axle but it was in vain. If you even tighten the cone nuts more than you should do the play is still there. What is happening and does this mean I need a new wheel? Thank you in advance!
If the play is in the wheel, a thought is that the bearing cup in the hub body is loose.  How that would be, I am not sure.  If you can tighten the cones to "too tight", that rules out a broken axle.  Grab the axle and see if you can get it to move.
