Pull the axle, put the lugnuts back on, rest the axle on something so you can hammer out the old sutds. I also stack some washers and tighten it up uni tthey are pulled all the eay in. Its easier to use washers instead of moving your rim/tire weight around.
When I snapped all 5 stock studs off one time I went to the next size larger, drilled out the rims, front hubs, rear axles, rear drums and sucked them in again. Works great! My aluminum rims were getting cut rather deep by the lugnuts anyway.
