How to put wheels back on garage door.
Top roller is the easiest garage door wheel to put back.
Use pliers to pry open one side of the track so the opening is wide enough to slide the roller back in.
A simple way to do this is to put a small piece of wood inside the opened track which will support the shape of the track.
When all the rollers are back inside the track you can close the opening in the track.
If you never want to have to worry about replacing your garage door rollers again i recommend going with a nylon roller like the dura lift ultra life max roller which you ll see me install a little later on.
Continue working on the rollers one at a time until you ve replaced all but the top 2 rollers.
This quick video shows you how to easily fix a garage door wheel that s out of the track.
Repeat for each of the rollers that have come off the track sliding them back in.
Open the door manually.
Once you locate where the wheels on the door are jumping off the track snap locking pliers underneath the door on one of the tracks.
The pliers act as a stop.
