Bottom Roller Replacement

How to Replace Rollers

These instructions are only for replacing the rollers that are supported by the bottom brackets. This roller can be found just a few inches off the ground when the door is closed. For additional roller replacement instructions, visit our Top Roller Replacement or our Middle Roller and Hinge Replacement tutorials.

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 track still contains the roller, 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
