In a wide angle universal joint wherein an inner double fork is connected with an outer fork having a pair of outer yokes by a trunion cross with spherical trunnions being provided for guiding the outer yokes and with a centering disc engaging the spherical trunnions with guides, the centering disc being secured against axial displacement but being radially movable, a lubricating system is provided which includes lubricating nipples on the trunnion cross for feeding lubricant into the system and lubricating channels extending through the trunnion cross and the spherical trunnions, with the lubricating channel in the trunnion cross having an output opening which corresponds with the input opening of a lubricating channel in the spherical trunnion at a position of the output yokes, with a sealing member being provided in one of the output or input openings. The sealing member may be a movable piston arranged in the output opening of the trunnion cross.
