The invention relates to the field of automotive parts, and specifically relates to a production process flow of an automotive steering linkage joint assembly. The process flow comprises the steps that: 1.1, raw materials used for producing a joint and a ball pin are prepared; 1.2, the raw materials are subjected to processes such as machining, milling, planning, and clamping, such that rough blanks of the joint and the ball pin are obtained; 1.3, the rough blanks are subjected to a heat treatment; 1.4, the treated rough blanks are subjected to abrasive machining; 1.5, ultrasonic flaw detection is carried out; 1.6, the joint and the ball pin obtained after processing and flaw detection are tested; and 1.7, a finished product is assembled by using the joint, the ball pin, and other automotive steering linkage joint assembly parts. With the process flow provided by the invention, working efficiency is greatly improved, and qualities of the joint and the ball pin are greatly improved.
