The invention discloses a testing tooling for moment performance of a steering device pull rod assembly. The testing tooling comprises a positioning mechanism, a guide plate and a scale plate, wherein the positioning mechanism is used for positioning and fixing a spherical shell of the pull rod assembly; the guide plate is provided with a guide groove used for allowing a pull rod body of the pull rod assembly to be inserted into and guiding the pull rod body to swing; the scale plate is movably arranged between the guide plate and the positioning mechanism; moment indication scales are marked on the scale plate, and have corresponding moment values. The testing tooling provided by the invention has the advantages that the moment performance of the pull rod assembly can be quickly, precisely and effectively tested, the testing efficiency is high, the one-time product passing rate in the assembly process is increased, and the detection on supplied materials and incoming goods can be effectively monitored.
