I want to Waterproof my Diffs on my rocky what do i need to do?
went down the rakaia on wed an had a play down one of the Smaller side streams got home an noticed i was leaking diff oil! oops!!!

Cheers in advance another question from a Novice

Where was the oils leak from? As for "waterproofing" them, you need to make sure that you extend the diff breathers so that water isn't sucked in, and make sure that the breathers are clear/unblocked.
I have extended the breathers on the Safari (incl. gearbox/transfer case) up to the firewall, and used small petrol filters on the end to prevent dust getting in.
