Hard to tell. Maybe there’s small gap, but hard to judge the perspective.
I guess only thing I can do is to replace both the joint and the ball (if that’s even a replacement part)? I see no way of checking whether shaft is bent without taking the joint apart and I think you can’t put it back together without plastic part replacement?
