Well, I've lookaed at the things for hours now (steel centered Phil hubs). I've pulled on them. Tried to twist them. Poked. Prodded, and even banged on them. Can someone please tell a home mechanic how to get one of these things apart, remove the bearings, replace a 120mm axle with a 126 mm axle. Thanks in advance for your time.
