Man I tell ya one thing properly tourqed drive shaft bokts with red lock tight is one of the hardest damn things to loosen every curse word used heating does help . Blue lock tight is plenty.I wouldn't expect the driveshaft bolts to be replaced - they typically don't "wear" and are safe to reuse indefinitely. It seems in this case they didn't torque them properly or didn't apply loctite. As mentioned, the bolts come from the factory with thread-locker pre-applied.
