Abstract:
An apparatus (12) includes a housing (142), a ball stud (170), a first bearing layer (110), and a second vibration dampening layer (120 or 130). The housing (142) defines a chamber (160) and has an opening (147) in communication with the chamber (160). The ball stud (170) has a ball portion (172) located in the chamber (160) and a stud portion (174) extending from the ball portion (172) through the opening (147). The ball portion (172) has a center (180). The stud portion (174) has a longitudinal axis (181) intersecting the center (180). The first bearing layer (110) is disposed in the chamber (160) and engages the ball stud (170). The ball stud (170) is rotatable about the center (180) relative to the first bearing layer (110).
