I just learned how to do this myself. It was super easy. It was trial by error for me to figure it out. Take the track off the top and slide the door out from the bottom. You then want to match the old rollers depth to the new ones. It's also super easy to adjust the depth too. I would also advise taking a video or pictures as a guide.Anyone know now to remove the sliding screen saloon door can be removed to replace the rollers? I have run a search but no luck. Looks like the fixed glass panel might have to be removed?
