The borate ester additised gear oils that Caltex (Chevron-Texaco) and Penrite sell have excellent EP performance, better than most all Sulfur-Phosphorous gear oils, but again, they don't mix well with water.

SAE140 would've been fine IMO, I think my swivels have an 80W-140 in them.
Yes i have also read that. In general gear oils seem to be a little hydroscopic like brake fluid. Personally i think no oil and water should mix so best to make sure its well sealed. Any grease is a srtip down but atleast the oil can be drained. Problem then is cost of the super high pressure oils that probably should be used with a cv when not running grease. Not being a lube expert though i would have thought the pressure between gear teeth in a racing transmission or differential would be very high and oil also doesn't keep the heat localized at the point of friction as it drains away.
Having said that the Toyota T50 box in my little race car was coated inside with lightweight shockproof and i found it was very sticky. Changed to their MTL though as it pumps easily through a cooler where the Shockproof is a strange "hard" sort of liquid that dosnt pump well. I do use it in my transfer case though. Leaves blue spots on my driveway now!
