transfer case tech questions

[trusted_expert]

so i have the 1354-m behind an m5od and just the other day i started getting a weird vibration outta the drivetrain like a bad u joint except mine are good. then i started hearing a clunking noise when coming to a stop and determined my transfer case was making this noise as i could feel the vibrations through the shifter. im thinking a toasted bearing but im really not sure?
