A method for the assembly of universal joints with radially pretensioned fork arms, consisting of the steps of inserting and positioning the joint cross in the joint fork, pressing in the bearing and fixing them by means of pressure units, one of which supports each fork arm and pretensioning each fork arm individually during the entire pressing-in and/or fixing phase by means of the tipping force resulting from the pressure prevailing between the support element and the pressing/peening tool, reduced by a partial force following in response to the amount of the pressing force.

An apparatus for assembling universal joints consisting of a machine stand (1) with devices (7) for clamping at least one joint fork (6) and a joint cross (8), two pressure units (2), one of which is assigned to each fork arm (5), each pressure unit having a hook-like support element (17) holding the fork arm (5) from behind, and a pressing/peening tool (16), characterized in that the pressure unit (2) includes a secondary pressure system (12), whose pressure-actuated element (19) is movable in the direction of movement of the main pressure system (11) and is braced against the machine stand (1).
