The invention relates to a design method of a shock absorber support locating device. The shock absorber support locating device comprises an angular adjustment disc, height adjusting devices, a locating beam and a locating pin, wherein a cross section of the angular adjustment disc is of a carving-lined oblique angle. The number of the height adjusting devices is two sets and the height adjusting devices are respectively arranged at two ends of the locating beam. One end of each set of the height adjusting device is fixedly connected with the locating beam and the other end of the each set of the height adjusting device is fixed with the angular adjustment disc. The angular adjustment disc is connected with a shock absorber support through the locating pin. The design method of the shock absorber support locating device has the advantages of improving the locating precision of cars in the vertical direction, up and down heights and the front and down directions.
