Exactly this ^^^ the enemy of locktite is heat but not too much, don't get anything even near red hot.It should be loctited. Apply heat, use a breaker bar so you can feel what's happening - NOT a mega impact wrench.
And don't use anti seize to reassemble, use loctite.
I would ask the company who made the parts about this. And which loctite to use, I would assume Red.
