1. A ball-and-socket joint, comprising: a ball stud comprising a ball at an end thereof, anda socket in which the ball is positioned for relative movement between the ball and the socket, the socket comprising a base, an endless retainer ring, fasteners removably attaching the endless retainer ring
1. A ball-and-socket joint, comprising: a ball stud comprising a ball at an end thereof, anda socket in which the ball is positioned for relative movement between the ball and the socket, the socket comprising a base, an endless retainer ring, fasteners removably attaching the endless retainer ring to the base, and a split bearing ring that is positioned on the base, cooperates with the base to define a bearing surface receiving the ball, and is captured by the endless retainer ring and the base therebetween upon attachment of the endless retainer ring to the base by the fasteners so as to retain the ball in the socket. 2. The ball-and-socket joint of claim 1, wherein the endless retainer ring is configured to distribute a load transmitted thereto among all the fasteners. 3. The ball-and-socket joint of claim 1, wherein the endless retainer ring comprises a cam surface in contact with the split bearing ring to cam opposite ends of the split bearing ring relative to one another in response to relative movement between the endless retainer ring and the base toward one another upon tightening of the fasteners. 4. The ball-and-socket joint of claim 1, wherein the endless retainer ring comprises an inner chamfer, and the split bearing ring comprises an outer chamfer mating with the inner chamfer. 5. The ball-and-socket joint of claim 1, wherein the base comprises an end surface facing toward the endless retainer ring in an axial direction relative to an axis of the socket and configured to receive a shim thereon and a shoulder recessed axially from the end surface relative to the axis, and the shoulder comprises a shoulder surface facing in the axial direction and positioned in fixed relation to the end surface and on which the split bearing ring is positioned. 6. The ball-and-socket joint of claim 5, comprising a shim removably positioned between the endless retainer ring and the base on the end surface of the base apart from the shoulder surface, wherein the split bearing ring is positioned on the shoulder surface both when the shim is positioned between the endless retainer ring and the base and when the shim is absent between the endless retainer ring and the base. 7. The ball-and-socket joint of claim 5, wherein the split bearing ring is positioned in contact with the endless retainer ring and the shoulder surface. 8. The ball-and-socket joint of claim 1, wherein the endless retainer ring comprises an innermost diameter greater than an outermost diameter of the ball. 9. The ball-and-socket joint of claim 1, comprising a shim positioned between the endless retainer ring and the base and disposed about the split bearing ring. 10. The ball-and-socket joint of claim 1, wherein the portion of the bearing surface defined by the split bearing ring blocks pullout of the ball from the socket, and the portion of the bearing surface defined by the base limits insertion of the ball into the socket. 11. The ball-and-socket joint of claim 10, wherein each of the portion of the bearing surface defined by the split bearing ring and the portion of the bearing surface defined by the base mates with an outer surface of the ball. 12. The ball-and-socket joint of claim 1, wherein the split bearing ring is made of a material softer than the ball. 13. The ball-and-socket joint of claim 1, wherein the endless retainer ring is attached axially to the base relative to an axis of the socket, and the split bearing ring is captured by the endless retainer ring and the base against axial movement relative to the endless retainer ring and the base along the axis. 14. The ball-and-socket joint of claim 1, wherein the split bearing ring is positioned in contact with the endless retainer ring and the base. 15. The ball-and-socket joint of claim 1, wherein the split bearing ring is positioned between the endless retainer ring and the ball, spacing the endless retainer ring and the ball apart from one another. 16. The ball-and-socket joint of claim 1, wherein the split bearing ring provides a first bearing portion of the bearing surface, the base provides a second bearing portion of the bearing surface, and the first bearing portion and the second bearing portion are positioned respectively on opposite sides of an equator of the ball. 17. The ball-and-socket joint of claim 1, wherein the endless retainer ring drives opposite ends of the split bearing ring toward one another as the split bearing ring reacts on the base in response to relative movement between the endless retainer ring and the base toward one another upon tightening of the fasteners. 18. The ball-and-socket joint of claim 17, wherein the base comprises an end surface facing toward the endless retainer ring in an axial direction relative to an axis of the socket and configured to receive a shim thereon and a shoulder recessed axially from the end surface relative to the axis, the shoulder comprises a shoulder surface facing in the axial direction and positioned in fixed relation to the end surface and on which the split bearing ring is positioned and reacts upon tightening of the fasteners, and the endless retainer ring comprises an innermost diameter greater than an outermost diameter of the ball. 19. A work vehicle comprising the ball-and-socket joint of claim 1, a blade, and a blade lift mechanism, wherein the blade is attached to the base, the blade lift mechanism is attached to the ball stud, and the endless retainer ring comprises an innermost diameter greater than an outermost diameter of the ball.
