A mirror assembly including a mirror that forms part of a mirror head to which a ball-and-socket joint module is mountable, the ball-and-socket joint module facilitating movement of the mirror head in response to an adjustment force applied by a user to adjust the mirror to a desired set position, comprising: a multicomponent ball assembly including first and second cups that have respective first and second inner cavities in which a spring is seated, the first and second cups having respective first and second outer bearing surfaces, and the first and second cups (34, 72) configured to fit together to contain the spring seated in the first and second inner cavities (78, 84) and to move closer to and farther from each other in response to forces applied by the spring seated in the first and second inner cavities (78, 84); a mirror mounting arm positioned outside the second inner cavity of, and extending from, the second cup; a multicomponent socket assembly including a mirror housing that forms part of the mirror head and a retainer that has a central aperture, the mirror housing having a depression forming a first portion of the multicomponent socket assembly and receiving the first outer bearing surface of the first cup, and the retainer having a surface forming a second portion of the multicomponent socket assembly and receiving the second outer bearing surface of the second cup, the mirror mounting arm extending through the central aperture of the retainer; and a connector securing together the mirror housing and the retainer of the multicomponent socket assembly so that the first and second portions of the multicomponent socket assembly contact, respectively, the first and second outer bearing surfaces (32, 74) of the multicomponent ball assembly and thereby compress the spring seated in the first and second cavities (78, 84), the compressed spring pressing the first and second cups (34, 72) against the respective first and second portions with a retention force of sufficient magnitude that allows the user to apply the adjustment force to move the mirror mounting arm in circumduction and rotation when adjusting the mirror to the desired set position and retain it there when the user stops applying the adjustment force, characterized in that one of the first or second cup includes longitudinally extending alignment fins and the other one of the first or second cup (34, 72) includes slits to receive the longitudinally extending alignment fins, the longitudinally extending alignment fins being slidable in the slits to guide axial movement of the first and second cups relative to each other. a multicomponent ball assembly including first and second cups that have respective first and second inner cavities in which a spring is seated, the first and second cups having respective first and second outer bearing surfaces, and the first and second cups (34, 72) configured to fit together to contain the spring seated in the first and second inner cavities (78, 84) and to move closer to and farther from each other in response to forces applied by the spring seated in the first and second inner cavities (78, 84); a mirror mounting arm positioned outside the second inner cavity of, and extending from, the second cup; a multicomponent socket assembly including a mirror housing that forms part of the mirror head and a retainer that has a central aperture, the mirror housing having a depression forming a first portion of the multicomponent socket assembly and receiving the first outer bearing surface of the first cup, and the retainer having a surface forming a second portion of the multicomponent socket assembly and receiving the second outer bearing surface of the second cup, the mirror mounting arm extending through the central aperture of the retainer; and a connector securing together the mirror housing and the retainer of the multicomponent socket assembly so that the first and second portions of the multicomponent socket assembly contact, respectively, the first and second outer bearing surfaces (32, 74) of the multicomponent ball assembly and thereby compress the spring seated in the first and second cavities (78, 84), the compressed spring pressing the first and second cups (34, 72) against the respective first and second portions with a retention force of sufficient magnitude that allows the user to apply the adjustment force to move the mirror mounting arm in circumduction and rotation when adjusting the mirror to the desired set position and retain it there when the user stops applying the adjustment force, characterized in that one of the first or second cup includes longitudinally extending alignment fins and the other one of the first or second cup (34, 72) includes slits to receive the longitudinally extending alignment fins, the longitudinally extending alignment fins being slidable in the slits to guide axial movement of the first and second cups relative to each other.
