Summary:A method of manufacturing a suspension assembly for a structure in a turbojet engine is provided. The assembly comprises: a first structure 23, arranged to be rigidly connected to a housing of a turbojet engine; a second annular structure 21 surrounding the first structure 23; and a hyperstatic trellis of connecting rods 40a, 40b, 40c, 40d, 40e, 40f maintaining the first structure 23 relative to the second 21. The method comprises a step of mounting the connecting rods of the hyperstatic trellis between the structures 21, 23 and a step for pre-stressing at least one of the connecting rods to a predetermined level. The pre-stressing step is carried out before the mounting of the connecting rod between the structures. Reference is also made to a device which is suitable for mounting the pre-stressed connecting rods.
