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 in the socket member by a main bearing ring, a pair of wear rings, and a pair of load rings. A lubricating grease is supplied to the interface of the ball of the stud member with the bearing and wear rings by a plurality of circumferentially spaced grooves extending generally axially across the bearing and wear rings. The grooves in the wear rings communicate with lubricant reservoirs defined by the housing member in cooperation with a cover and a flexible seal member adjacent opposed polar regions of the ball of the stud member.
