No fluid puking problems, and it is not noticeable at all in high range on the street.
In high range, it is essentially just an intermediate shaft supported with two bearings, so I don't see any reason why it wouldn't be fine in a daily driver as long as you keep the fluid filled to the correct height.
The planetary is just free spinning in high range with no load right?
