ABSTRACT:
An upper control arm for a vehicle suspension system and a method of making the same to form a reinforced arm for receiving a ball joint assembly. The arm is constructed by inserting an aluminum rod into a straight piece of steel tube with aluminum insert positioned at the center point of the tube, the tube is bent into the general shape of the control arm. The apex of the arm containing the aluminum insert is flattened into a substantially oval cross-sectional configuration. A hole is tapered reamed at the apex through both the tube and the aluminum insert to receive the ball joint assembly. As a result, critical sections of the control arm are reinforced yet a lightweight construction is maintained.
