An articulated joint for an articulated vehicle. Upper and lower pivotal connections, each employing a ball and socket, allow pivoting of two vehicle sections about a vertical axis. The ball of the lower joint is attached to one section while the socket is attached to the other section of the vehicle. The socket and ball of the upper joint are attached to a support member free to move along a shaft in a transverse direction between two stops. The ball of the upper joint is free to move along a vertical shaft joined to the other section of the vehicle. The transverse shaft provides a bearing surface to transmit loads between the two vehicle sections. Seals along the support member prevent entrainment of dirt along the shaft and bearing. The stops are part of the structure attaching the transverse shaft to the vehicle.
