ahh,your still need to get the geared part of your hub out,did you take the outter lock ring out,if not you have to push that gear in and around the outside edge there is a small ring,if you have two o-ring pics or two small slot screw drivers find the edges of that ring and pop it out.and if you already have the snapriing of the axle the hub will pull out,you may need to thread a couple screws back in to give you something to pull on if its a little sticky.
once you get that out you'll need a 4x4 hub sockets.
