The first challenge was getting the rollers out. After some head scratching, we figured out the correct 43 step process to get them out safely. After removing them, reinstallation was easy. We actually reused the old rollers, but we flipped them. The top rollers switched to the bottom and the bottom went to the top.
|The rustier roller was on the bottom.
Once everything was back in place, the doors slid like new. Another very satisfying project.
