It it is a good freewheel, like SunTour or Shimano, I'll rebuild it. Yes, take it apart, corral all the tiny little ball bearings and clean it all up and grease the bearing races and put just a tiny dab on the pawls. And put it back together usually with the slimmest shim removed.
I am obsessive and don't have time to do many things that I need to do, but for this, I do it.
If I had a therapist, I sure that would be one of the many issues they would be working on with me.
