The present invention provides a bearing cup assembly for a universal joint comprising a cylindrically elongated bearing cup, the bearing cup having a cylindrical sidewall, a closed bottom wall, and an open top. The bearing cup is positioned over, and rotates freely on, a cylindrically elongated trunnion which is associated with the universal joint. The bearing cup assembly further comprises a lubricant-impregnated powder metal mass disposed within the bearing cup and positioned between the sidewall and closed bottom wall of the bearing cup and the trunnion. The assembly further comprises a circular seal having an open center and being disposed about the open top of the bearing cup. The trunnion is disposed within the open center of the circular seal and the seal is in close interfitment with the open top and the trunnion so as to form an impenetrable closure therebetween.
