Bottom Roller Replacement

How to Replace Rollers

These instructions are only for replacing the roller that is supported by the bottom bracket. This roller can be found just a few inches off the ground when the door is closed. Go here for our tutorial on replacing the roller on the top of the door. Go here for our tutorial on replacing a roller in the middle of the door.

Replacing the bottom roller on a garage door can be extremely dangerous for do-it-yourselfers when done incorrectly. When you install a new roller, do not loosen the bolts that secure the bottom fixture to the garage door. Additionally, do not remove the cable from the bottom fixture. Failure to adhere to these warnings may cause the door to cock, jamb, or fall, resulting in property damage and/or personal injury or death.

1. Pull the bottom section of the garage door toward the inside of the garage and remove the old roller. If the roller is still contained by the track, bend the track as shown in step four. This will allow you to remove the roller from the track. It will be easier to replace the roller if you raise the door a few feet off the ground. How to Replace Rollers
