1. A method for producing at least one of a ball joint and a chassis component, in which a joint ball is located, the method comprising:
placing the joint ball in an injection-molding die,
partially overmolding the joint ball with a plastic material,
hardening the plastic material to form an injection-molded joint housing for the joint ball, and, during formation of the joint housing, the joint ball is overmolded without a joint pin, and the joint ball has respective first and second pole surfaces on two sides remote from one another.
