Thanks Hammered. I drove the truck about 16 miles in traffic, etc. so it had plenty of time to heat up. The noise occurs as soon as I go into 5th regardless of whether it was at the beginning or end of the drive. It just seems to "tone down" after I've been in 5th for a while.

I guess I'm just trying to explain it away as normal so I don't have to pull it back out, but it's not sounding like it I could cover it up enough to drown out the noise and hope things don't explode or pull it back out and deal with it now.
