Hello folks, my latest misadventure is a stripped rear hub. Photo here:

I just purchased this wagon a few months ago, and this is the first time I've removed the rear wheels. So, good thing it wasn't my fault I guess.

Anyway, from what I understand rear hubs are awful to replace. Also, the rest of the threads are ok.
Instead, can I just tap a bigger hole and get a larger lugnut to match? From what I understand, inserts can be used too, but I have never used one before.

Any wisdom, from folks that have delt with this would be appreciated!
