The shop manual says that the nuts holding the front driveshaft flange to the yoke at the back of the transfer case are non-reusable. Anyone know why? Anyone reused them? I’m about to dig into the parking brake assembly to fix my loose shoe. Also says o-ring behind large yoke nut is not reusable. Really don’t want to have to hang around for more parts. Took me two weeks to get the parking brake parts.
