The invention relates to a universal joint arrangement with a journal cross, supported by bearings in two joint yokes offset to one another by 90° and in reflected arrangement to the plane of symmetry of the journal cross located perpendicular to the joint axis; each joint yoke comprises a flange part and two bearing parts, wherein each bearing part exhibits a bearing bore, in which the journals of the journal cross are supported by bearings; each journal is supported by means of a bearing arrangement; the bearing arrangement comprises one radial bearing and one axial bearing, wherein the axial bearing is designed as a friction bearing. The invention is characterized by the following features: the axial bearing comprises at least one axial friction bearing mold element which under formation of a first friction pairing supports itself at least indirectly on the joint yoke and a second friction pairing supports itself at least indirectly on the journal cross; the axial friction bearing mold element comprises a first plane frontal area and a second one which is characterized by at least one elevation region; the elevation region forms a support region, which forms a friction surface of the first or second friction pairing; the axial friction bearing mold element is arranged in such a way that it rests in the state without active operational load of the universal joint arrangement with the support region on the connection element and elastically deflects under load in said support region, wherein the regions free from the support region on the second front side are in every load state free from contact with the connection elements and wherein in installation position the support region is arranged in the region of low relative movement of the connection elements, while the regions free from the support region lie in installation position in the region of greatest relative motion.
