The carrier is the biggest weak point anyway. So if you went with any selectable locker it would be much stronger instantly.
And I know nothing about g2 gears, but if that happened with minimal abuse, maybe look into a different brand of gears lol.
If your running 8 lug now, then what he said /\/\.
Or if 6 lug still find a sf14b with 6 lug from a newer truck.
You'll be money ahead in the long run, and probably gain rear disc in the process.
10b can be built to be strong. But it's still only a 10b
