The oil can be filled from either the oil fill hole, if present, in the hub or through the rubber plug hole in the cap itself. ”
As I mentioned before, not all caps have a ‘level line’, especially the older white plastic caps.
What that link dances around is ‘periodically check and fill if necessary’’.
If it needs fluid it most likely needs service.
The truck videos in the next post are not relevant to this thread.
