Abstract
A ball joint assembly having a ball stud member received in a socket member. The ball of the stud member is retained in a recess of the socket member by a bearing ring urged to bear on the ball by a pair of elastic load rings. A seal received on the socket member defines a lubricant reservoir which is supplied with grease through a grease fitting carried by the socket member. A plurality of passages defined in part by various grooves in the load ring and portions of the bearing ring interconnect the lubricant reservoir, grease fitting and interface of the bearing ring with the ball of the stud member.
