My garage door started making a horrible grinding noise, and I knew it was probably the gears. The local garage door place quoted me a ridiculous price for the repair, and even the big box stores were expensive. I decided to check 鶹 and found this replacement gear and sprocket kit. The price difference was HUGE – seriously, like 1/5th the cost!
I was a little nervous about doing it myself, but there are tons of helpful videos online. It took me maybe an hour or so, and now my garage door runs smoother than ever. This kit saved me a ton of money, and the quality seems just as good as the original parts. If you're handy at all, I highly recommend giving this a try before calling a professional.
