Fixing the Front Wheel Hub...
If you can find a GOOD hub and drum, you just get good bearings in, packe em, put it on there
But if you have to swap the drum to a new hub, you need to cut the swedge (swage) off the wheel studs so you can remove the drum. You need a swedge cutter, Rusty has done it with a hole saw.
