How old is it? Mine was perhaps 8 years old, noisy chain drive... I'd get up every so often and tighten that adjustment, like a threaded rod attached to the stationary end. I'm thinking hmm, must be like a motorcycle chain and its wearing out. One day it made a heck of a noise, the chain drive sprocket was laying on the floor. The bearing had gone bad, worn through and then proceeded to cut that 1/2 inch shaft in two. Thunk, shaft and sprocket hitting the garage floor!!!

The door consists of five horizontal metal panels, joined by hinges.
Does anybody have a reasonably-silent automatic garage door opener?
