Not sure but this does not sound right.
Have you checked the driveshaft bearing support? this will make the exact sound under the conditions described.
If your pin was that loose I would think you would have rear end noise at shift points, foot off the pedal, and likely may other times.
I may be way off but it just does not sound like the pin is the issue.
There is my idea without ever seeing or hearing you car. Take it for what it is worth.
