The definitive tightening of the nuts fixing the shock absorbers and the leaf springs to the supports should be carried out in design load conditions. Therefore a suitable load must be applied to the vehicle over the rear axle so that distance (L) between the buffer plane and the buffer support plane corresponds to the recommended figure (leaf spring in horizontal position).
