Jeep Gladiator Ticks Part 1

Attempting to track down a ticking sound on the Jeep Gladiator. 2020 Mojave with 46k miles. The sound seems to originate around the transfer case and is felt within the cab at low speed.
Although the Gladiator features Johnny joints and other modifications, it has been quiet until now. If I have a noise, I can usually track it down and address it.
In this video, I have attached a GoPro in various areas. Beside the transfer case, viewing the front of the drive shaft and towards the rear axle. The gladiator has a split drive shaft, so I mounted the camera viewing between the halves.
