Apparently all these years of fighting with the closed level is because the shuttle was slowly eating away at the plastic carriage, slowly gouging it until I had to reset the closed level, and then the cycle would repeat. So I was able to order one.

I actually ordered it from Amazon after painstakingly wading through off brand listings.

Not that I really need this, or would follow it exactly anyway.

Re: Genie PowerLift 900: carriage almost failed
Removed the old one by overriding the low level limit and just letting the screw push the carriage out of the track. But getting the new one in was tricky. There is a metal piece that rides on the screw that is simply held in place by a spring. There is no other positive retention and this makes inserting the carriage into a turning screw fairly precarious. The directions want you to disconnect the screw from the motor which for me would require dropping the entire opener motor since it is mounted nearly flush with the ceiling (low ceilings). Instead I had Ian manually press the raise limit button to manually run it in the right direction while I carefully inserted the carriage into the turning screw. Probably dangerous for the fingers. And first time it rejected it and I think broke some teeth on the new piece that goes into the carriage. But second try I got it. Greased up the screw a bit and it's actually noticeably quieter than before.
The door itself is at end of life though...
