Abstract
In the present invention a tubular blank and an article such as a bushing to be assembled are loaded into a die. The tube is hydroformed using typical methods and, while the blank is still pressurized, a punch pierces a hole in the tube. The punch also has an article loaded onto it and, as the punch advances, the article is pushed into the tube through the pierced hole. The punch continues to advance such that it pierces a hole in the opposite side of the tube. The punch then retracts leaving the bushing in the tube. The article may alternately be inserted by means separate from the punch.
