ABSTRACT:
An upper arm 1 of a front suspention made of light alloy is provided with a lateral rubber bush mounting bore 2 connected to a vehicle body, and a vertical joint mounting bore 6 connected to a wheel support member. When forming the arm 1, a shape of the arm 1 is first determined such that the mounting bores 2 and 6 are directed in the same direction. Then, the arm 1 is extuded in an axial direction of the bores, and after cutting off the extruded material at a predetermined length, a portion of the mounting bore 2 is twisted by 90.degree.. Therefore, the extrusion can be employed for producing the suspention arm made of light alloy without increasing a thickness thereof.
