But I've been running it now for well over a year with no problems and have largely forgotten about it. Had it up to 140mph with no actual vibration or problems.
I wrote off the additional NVH as well. Most of my research showed that this was pretty normal. I don't do too much highway driving, so it didn't bother me.

This is a new issue with a new noise coming from the driveshaft (see 1st and 2nd video in my previous post). It's also noticeable when driving at all speeds.
