The first thing you need to do is remove the head stop at the top of the unit on the inside. This will have about six to eight screws that hold it on. Once you remove this the door panel will tilt to the inside. Becareful some panels are very heavy and will require two people to remove the panel. Next; you want to lay the panel down on its side and remove the rollers. There are two types of rollers one has two screws that hold it on and the other is pressed in to the bottom of the panel. If you have the pressed in type, take a screwdriver and stick it in behind the roller and pry out. Then just install the new roller and reverse the process of putting the panel back in the opening.
You should also clean out all the tracks, before reinstalling the panel, this will assure that every thing is clean and clear of dust and dirt, so the new rollers won’t stick.
