Gorbachza

well I replaced my cassette last night and saw that it does not have sealed bearings. I see new Hubs in my future...

oh goodness no... I don't know what make it is but it is not XT/XTR.

I am in the process of upgrading my MTB, and the next part I am buying is a new front shock. I would like to know if a 15mm through axle will work with my standard hubs or do I need to upgrade/change it. I know the standard skewer is like 5mm so obviously something would have to change. Any advise would be appreciated.
