Abstract
The invention pertains to a method for manufacturing a ball joint composed of a ball-ended spindle (1), bearing shell (2) and socket, provided with a sealing boot (4) arranged between the socket and ball-ended spindle (1), in particular for a motor vehicle, by means of extrusion coating, with plastic in a split injection mold (6) the ball-ended spindle (1) provided with a bearing shell (2) placed on the ball (11). In order to create a ball joint which can withstand high stress and limit the assembly work required to complete the same, the housing-side opening bead (41) of the sealing boot (4) is positioned on the bearing shell (2), before loading the ball-ended spindle (1) in the injection mold (6), and is located between the bearing shell (2) and housing (3) by means of an extrusion coating.
