nice pics, they are too small though! as for water, i was taught that in manual hubs, repack them everytime they are underwater, if your seals are fresh, and your breather is not plugged, you SHOULDN'T have water getting sucked into the case... keyword is shouldn't... check them periodicly and you will be fine... if you see a lot of moisture, extend them higher... snorkels are good to add also, i've got one on my truck, it's just not visable... i sucked a bunch of water into my engine a few months back... (not hydro locked though) i filled my airbox with mud, airfilter was soaked, and MAF got dirty with mud coming through the filter, i'm sure i got some water into the engine too... i put the snorkel on about 3 weeks later...
as for your buddy's truck, he probably got a sensor or connector for something wet...
