A method of installing a windshield wiper device (10), the windshield wiper device including at least one wiper bearing (14) having an end surface and an outer surface and supporting at least one wiper shaft (16), which has at least one undercut (48) in which a securing device (40) for axially fixing the wiper shaft in the wiper bearing is arranged, which securing device is displaced by the effects of a defined axial force component (F) on the wiper shaft, whereby the wiper shaft is displaced in relationship to the wiper bearing, the securing device (40) comprising a bushing section (42) having a wall with an inner surface and an outer surface, a flange section (44) attached to the bushing section, and a bushing-shaped closure section (46) attached to the flange section, the method comprising positioning the securing device with the bushing section supporting the wiper shaft, the flange section engaging the end surface of the wiper bearing, and the closure section surrounding a portion of the outer surface of the wiper bearing, and pressing the bushing section with an external force to form an indentation (50), which engages in the undercut of the wiper shaft.
