Kraton Clicking noise from center diff (I think)

[kratonwatch]

Anyone have an idea what this clicking could be? Front and rear diffs just got an overhaul to vitavon gears and housing, but I noticed this while spinning the wheels. Really hoping it’s normal/acceptable because I don’t want to remove the center diff after just thread locking the motor into place.

try holding one wheel and spinning the opposite, try rolling the rears while front in air and still, and do same with fronts on ground
