Hi Jeff,
A long way off, but when I got my GM811G HD, I mounted the motors as instructed.
The Dec axis was a bit loud. So I did the described 1/4 turn loosen and tried adjusting the motor.
It got quieter. Not silent, but quieter.
The square cut gears used in these mount (Also referred to as Bull Gears, because of how strong the design has been in industry) are know for being a bit noisy.
Long I have heard of complaints by some about mount noise. All types of mounts, actually. Neither of my mounts have ever been silent, and not would I expect them to be.
They are machines and when running at high speed, I would expect them to be noisy to some extent.
Mine has gotten quieter as it has run in.
Scott and Brian advised me when I picked mine up, "Don't mess with it. Just use it." Sage advice.
