Door Rollers not Rolling!

My sliding indoor barn doors are not sliding functionally at all. Every time the door is supposed to slide I hear nothing but creaky, grinding, sticky, scraping, and very noisy ear cracking, nail on chalk board noise!
I needed it to stop! I need a repair since these were quite expensive and not that old!
I knew I had to fix them myself so I gathered my supplies which were Wd-40 and a soft cloth. This is what I did;)

I got busy and cleaned the tracks and lubricated well the rollers. I generously gave the tracks extra lubrication hoping the friction would be resolved. I managed to get the track properly aligned and level too. I learned that some WD 40 could probably help prevent squeals and noise to ensure a smooth operational opening and closing:)

I tried the sliding door a few times, rolling smooth again. One little simple neglected repair finally done and successful.
Lubrication, aligned tracks and maintenance put my doors back to tip top shape.
