As you can see, it makes a strong resistance to move, and wants to get back in some specific positions. The antikating mechanism is not working as well, in general, the arm is not free to move, and that led to skips and mistracking.
From what i understood, the pivot bearings are gone, and since they are machine calibrated i got that makes no sense to mess with them, so i'm going to replace the entire piece.
