Recently, I installed two new tracks for two closets (both with two sliding doors a piece). The first track works great. The second track is having some issues, the back door rolls nicely,the front door moves but the rollers inside the track will not roll.
I have checked to see if something is obstructing the door from rolling on the rollers and cannot for the life of me find anything obstructing. Tried lubricating due to this post, but no luck there.
How do I lubricate plastic rollers for sliding closet doors?

Basically, what seems to be occurring it is as if the wheels are stuck as they do not turn when the door is slid, so the door will slide but it is rather loud. So, I pushed up with the door and I was able to turn the wheels so it is not like the wheels themselves are stuck.
I have also tried readjusting the roller bracket positioning several time just to see if that would help, but no luck there either.
