I am currently repacking the hubs of the wheels that came with my 2003 Specialized Hardrock. The wheels are made by Alex and have Joytech hubs. So far I have only started the front wheel. I am replacing the bearings with 3/16" bearings and they look to be the same size as the old. The problem is I can get one of the bearings in and aligned properly, but when I try to get the second side in I cannot get the cone to fit back in properly. It gets stuck higher up than it should be. I have cut into a couple bearings that were caught in it. I have taken apart the wheels and tried about 5 times to get them back, but I have had no luck. Is there a trick to getting the bearings in properly?
