Sliding door has been a huge pain in the ass, but its finally good now. All the rollers were screwed and needed to be replaced. I needed to take the frame apart since the rollers connect to the aluminum corner connector pieces. The adjuster bolts are steel and were galvanically corroded to the aluminum pieces. I had to take a few of the corners apart several times because the bottom rollers kept popping out while installing the door. The adjuster screws were supposed to close and aluminum piece around the plastic roller piece. But instead of pressing the screws just dug into the aluminum, so I needed to add some shims.
