2019-2024 Sierra/Silverado: 4X4 Transfer Case Oil Change

How to change the 4X4 transfer case fluid on a 2019-2023 Chevy Silverado/GMC Sierra. Same process for the Yukon, Tahoe, Suburban, and Denali; 2019, 2020, 2021, 2022, and 2023. Heat and load exposure are the determining factors for service interval. Obviously, doing the service early and regular can minimize breakdown of the fluid, preventing gear-wear and contamination that lead to seal, bearing, and/or electrical component failure. In general, an interval of 30-60,000 miles is recommended with the range dependent on driving conditions, ie. heavy start/stop traffic, towing, and extensive 4X4 operation. ***UPDATE*** Thread sealant should be used on the threads rather than thread locker.
