To fix it they added some additional silicone lubricant to the boot. I am not very handy when it comes to anything other than Jeep Wrangler/Gladiator lifts, so don't shoot the messenger.
None the less, this has been a HUGE headache that hopefully is behind me.
They did create a service bulletin because they said this problem was a bear to diagnose.

Glad the issue was solved. I too would have never guessed that would cause the issue.
What stumped me was the cadence of the noise didn’t change throughout an rpm increase.
But now, since you have been in touch with the lead tech at your dealership, you should keep requesting him to work on your T4R whenever it has to go in for service.
