Need to know how to put sliding closet door back onto track, is there a trick to it. I have tried everything:confused:

You have to remove what causes the door not to tilt at the bottom of the door.

Then push the rollers up and into the track at an angle and slowly lower the door, putting the lower part of the roller in place.

You might have to clean out the closet.

Replace the thing you removed.

It's also possible that some of the screws might be loose that hold the tracks in place making it more difficult for a re-install. So, you might want to check all of them to see if they are tight.
