Mine were locktited in place when new in 2000....still tight today.
I have a rule, always use one of 2 things, either some form of locktite to keep stuff from coming apart or some form of neversieze to allow stuff to come apart. I'm now old enough to be taking stuff apart that was treated my me decades ago and am now reaping the benefits. It's a ton better than taking apart stuff that is even just a few years old that was un-treated. Even with impact wrenches, it's worth doing.
