Abstract: A method of manufacturing a reaction rod for use in connecting a chassis (21) of a vehicle with a wheel axle housing (22) of the vehicle. The reaction rod comprises a rod (1) with two end portions, two housings (2,3), each of which can be securely connected with its rod end portion, and two attachments pieces (8,9), each of which extends through its passage (4,5) of the housings (2,3). The attachment pieces (8,9) are arranged to be attached to the chassis (21) and the wheel axle housing (22) respectively. The distance between reference points (16,17) of the respective attachment pieces (8,9) establishes a functional length (F) of the reaction rod.
