after you get it out theres a way you can put bearings in and prevent the problem from ever happening again.
get a 5/16 bolt and the proper locknut multiple washers and wrenches. then in order you slide on a washer, bearing, wheel, spacer, then bearing, washer. if there is a lot of extra room use spacers to take up space. put your locknut on the end. then you kind of guide the bearings in straight and once they're straight you tighten down the bolt. then it applys pressure to push in the bearings and at the same time keeps your spacer in the correct position.
