Abstract

A sealing element for a ball joint has a sealing area on the housing side and a sealing area a distance away therefrom in an axial direction of the sealing element on the stud side. Arranged between the housing-side sealing area and the stud-side sealing area is an outlet opening which extends through the sealing element to allow the passage of spent lubricant. The outlet opening extends in the axial direction of the sealing element, passing all the way through the sealing element in the axial direction. Further, the sealing element is incorporated in a ball joint which is incorporated in a two-point control arm.
