Oh, that... i put a thin layer of grease around the axle nuts and splines then just wrap it with electrical tape. Its just a thing i do/ keeps it all nice in there. I figure these axles are a dying breed so whatever i can do to help w/corrosion i guess.
Long story short is it keeps the water out, just a habit i guess.
Must be others out there that do the same??? Maybe???
When i know i’ll be in lots of water its just cheap insurance i guess
