I wondered that, too, and was trying to think of how they installed it at the factory and just duplicate that.
Best guess is they put some cuts in the top of the pin and pressed it down, but would think that it had to be before they welded the hinge onto the body as there isn’t a lot of room.
However they did it, it had to have been quick and easy ($).
Yes, GM stakes that pin in with two cross cuts and “peens” the top by mushrooming it. Which of course requires the top of the pin to be ground off to remove it—a Royal PIA.
Glad to see you pressed the roller pin in, pounding it in doesn’t work—I know this........
I found most of the aftermarket bushings and roller pins work fine if installed properly and if the uppermost hole in the top hinge where the hinge pin has a interference fit is PERFECTLY ROUND AND NOT WALLOWED OUT IN THE LEAST, TINIEST BIT.
If that hole is even microscopically wallowed out no bushings—not even GM bushings—will last long, and a droopy door also wears out the roller pin.
