Replaced the original one a couple years ago after it started making the slightest of noises. New one has been screaming for months, finally decided to have at it again.

The grommet in the photo. The weight of the motor and vibrations cause the grommet to get weak which allows the motor to drop slightly which causes the blower wheel to rub slightly on the housing.
Does not apply to all models obviously.
So is that just “replace this bushing when it wears out prematurely instead of getting the updated mounting kit”?
That’s all I did yes. I was able to prove it was the grommet by gently lifting the motor up which resulted in the squeezing going away.
Short term fix while I waited for delivery, was I swapped the lower and upper grommet as the lower one was my issue part while the upper was still good.
It’s been working without noise issues since last winter.
This all is too exciting for Dull Men’s Club.
Sorry, I shall tone it down.
Turns out mine was the motor. Already has the updated mounting orientation, looks like it was built that way. As you know, it’s a pretty easy job. I spent more time looking for an Allen key and then trying to extract that Allen key from the set screw for the squirrel cage than anything else.
