A well-maintained garage door can often last you a decade or longer. Unfortunately, this doesn’t also apply to your garage door parts. Chances are, you’ll need to replace things like screws, springs, hinges, and rollers long before you’ll need to buy a new garage door.
If your door has become particularly noisy, then it may be time for a garage door roller replacement. Replacing the rollers on your garage door is a simple task but as with all garage door repairs, a certain level of caution should be exercised.
Jeff Patterson of Home Repair Tutor sums up the safety requirements quite well here. In short, you should raise your garage door all the way up and clamp both sides of the tracks about 2/3rds of the way up. Place a ladder underneath the panel to help support it and disengage the emergency release. Make sure to also unplug your garage door opener to prevent operation during the repair. It may also be beneficial to have another person watch the door and your surroundings for safety.
To replace the roller, you’ll need to slightly bend the track with a pair of pliers and lift the old rollers off the rail. You can then remove the old rollers and install the new ones before placing them back on the track and reversing the bent rail to secure the new rollers.
Repeat this process for the remaining rollers. Once done, don’t forget to re-engage the emergency release, plug back in the opener, and remove the clamps from the tracks. Try operating the door a few times and make note of any noise or unusual movement. If it works as expected, then you’ve successfully replaced the rollers!
