Precaution: Ensure that you have unplugged your garage door opener to prevent electrical shock or accidental activation.

Prep Work

Place a clamp below your garage door roller. Lift and stabilize your door prior to removing any of the screws or bolts. It is best to replace rollers and hinges with your garage door in the raised position because it reduces the tension on the springs. It is possible to perform this with the door in the downward position; however, it requires completing several additional steps in the process to be safe.

Use a C-clamp to stabilize your garage door placing it just below the lowest rollers on the garage door tracks. A long board may be wedged below the door as well to secure it in the raised position. It may be necessary to disengage your garage door opener completely prior to beginning. Next, raise your garage door to the required height and then install the C-clamps in order to safely secure it.

The door panels may sag slightly once you remove a hinge. Boards or a ladder can be used to brace the door panels up prior to unbolting the hinge. In the best situation your garage door will only sag. In the worst scenario it may break. To prevent the support boards from slipping try clamping them to your ladder. This completes the prep work.


Loosen the nuts of the hinge bolts and gently tap them out using a hammer to release the hinge. It is best for the nut to remain unscrewed on the bolt to protect the threads. A scrap of wood may also be used to prevent damage to the threads. Disengage the roller from the track by tipping the hinge away from the door. You will simply need to reverse this process to install your new roller.

Most professionals recommend that you replace rollers while replacing hinges unless it is brand new. They are relatively inexpensive and they often wear out rather quickly. This will save time at a later date. It is best to take the worn out hinge along with you when you go shopping for the new ones. Most of the time you can locate a generic type hinge at just about any hardware or home improvement store. There is a wide variety of options for brands and sizes. Having the old hinge with you will eliminate the guess work.


Slip the roller into the appropriate hole and tip the roller back in the track to properly position the hinge over the correct holes when installing the new one. Gently tap the bolts back into the holes from the outside and then carefully tighten the nuts. Ensure that you have placed the roller axle in the right hole which is the one that was used for the old hinge. You can also use the one on the other side to compare it.

Garage door hinges are commonly affixed using carriage bolts. These are not like standard screws or bolts as no gripping surface exists on the head of the bolt. It is smooth in order to inhibit rust from developing and is also more aesthetically pleasing. It instead features a square lip below the head which locks in the wood portion of the door. It may not fully engage, if you neglect to tap the carriage bolt through before attempting to tighten the nut. This could cause you to strip the threads.

Once you have tightened all of the bolts down and removed all of the clamps you will need to test your garage door manually. It may be necessary to adjust the hinges, if the panels do not align correctly. Double check all of your hardware to ensure that everything has been properly tightened. Reconnect and engage your garage door opener.
