I'll let y'all know if I break a shaft. Until that happens, (and a trail-side shaft replacement ensues), I will not worry about it in the least.

Besides, I won't have to beat on it the truck as hard for some obstacles simply because I am not coping with the rear end spinning a tire due to my formerly worthless LSD.

Plenty of people have been building and wheeling the crap out of HBs and HB Pathy's with 31-spline axles. Very few are breaking. I'll keep wheelin.
