Made these videos trying to figure out how to fix this. Note the opener is not under load. Up close it sounds like its coming from the trolley but after greasing the square rail, sound is unchanged. Just looking for ideas. Thanks!

Sound sources can be misleading....I'd lube EVERYTHING that rotates or moves....pulleys, top of actual opener itself,
and anything else that might not seem like it's THE problem.....I've found that a lot o' times one can locate things
like this with a stethoscope....

thanks for the advice. I realized I could just send the links to the chamberlain support chat, and that guy told me to loosen the belt a little, now its quiet again.

A squeak is a cry for lubication.
