It looks like I need a transmission rebuild

In post #8 OP states that with car stationary and clutch in=depressed the car is "nice and quiet". With car moving and clutch in or out he hears the noise.

So with car stationary and clutch depressed the trans main-shaft is not spinning.

But with car moving the trans. main shaft is spinning with clutch in or out.
The axles spin the main shaft while car is moving with clutch in.

If you listen to the vid of the trans. main shaft being spun by hand something is not right in the trans.

So very possibly a trans issue.

I do agree the the vid of engine running does sound like power steering or idler pulley.
Removing the belt and running engine as suggested should tell all.

+1 on the tranny. I wouldn`t be surprised if the transmission oil was full of steel and metal debris.
