Get four or five of the inserts, as they are dirt cheap and in case one comes out later (although it shoudn't). The tool is a bit spendy, but required to do the job. Either way, it's cheaper than replacing the hub, especially if it's the rear on a wagon.

The damage may have been from over torquing with the impact gun, or could have been from galling coming out. Almost NOBODY ever anti-seizes wheel bolts. A friend runs a tire store and is careful to anti-seize EVERY lug bolt and nut he replaces for exactly this reason. A can of nickel anti-seize is just a few bucks and is worth it's weight in gold for preventing galling like this. Also put it on spark plug threads for the same reason. Thermostat housing bolts, etc... anything that goes in aluminum or acts like it might want to gall coming off or going on. Got hooked on using it at the pump shop taking apart corroded stuff and then at the hydraulic shop for large diameter fine threads. Sure makes life easier.
