How to Fix a Squeaky Garage Door Opener.

My squeak turned out to be the front pully. It took some effort to find. The garage door opener is a wi-fi enabled M3155D Aladdin Genie, only a few years old. I really like it, except for the squeak.

Great video. I had the opposite problem, no noise going up, just when it was at the last part of closing. At first I did the lithium on the hinges, but when that didn't fix it, I disconnected the door and saw it was the drive mechanism or the pulley. I assumed it had to be the bar needing grease, but it's probably what you had to deal with. Will let you know how it goes.

So what was it the belt guide? How did you fix it?
