The present invention relates to a method and an apparatus to manufacture shock absorber cover for vehicles. The method comprises: (S100) a first blanking step of producing a first processed goods (10); (S200) a first drawing step of producing a second processed goods (20) by forming a main groove (21) on the first processed goods (10); (S300) a second drawing step of producing a third processed goods (30) by forming a stepped protrusion (31) and a guide groove (32) on the second processed goods (20); (S400) a trimming step of producing a fourth processed goods (40) by cutting a contour of the stepped protrusion (31) and the guide groove (32); (S500) a restriking step of producing a fifth processed goods (50) by bending with precise dimensions based on the stepped protrusion (31) and the guide groove (32) of the fourth processed goods (40); and (S600) a piercing step of producing the finished products by respectively perforating an assembly reference hole (H1) and a wiring hole (H2) on the main groove (21) and the stepped protrusion (31). As such, a cover of a shock absorber which has a multistage complex bent shape can easily and precisely be produced.
