Trying to attach short clip video it won’t let me attach to my post?

I hope you can attach that video of the squeak at shutdown.  I have been noticing the same thing.  Seems to be coming from gearbox or prop shaft.  Turning the prop after shutdown, when hot, yields the squeak as well.  Hoping its not related to crankcase fretting as the force required to turn prop after shut down, when hot, is slightly higher as measured with a fairly accurate pull scale.
