How do you change rollers on a garage door?

To change rollers on a garage door, first, ensure the door is closed and disconnect the opener for safety. Use a socket wrench to remove the bolts securing the roller brackets, then gently slide the old rollers out of the track. Insert the new rollers into the track, reattach the brackets, and ensure everything is securely fastened before reconnecting the opener and testing the door's operation. Always wear safety gear and consider consulting a professional if you're unsure.
