is it true that after every time you drive through water over your axles you should change the oil in your diffs? some dude told me this and it doesn't seem right. if this is true i should have gone through a couple litres of oil every week. any info would be appreciated

If you are refering to taking your mog through the water. You don't have to change the dif fluids. The dif vents go up under the hood, so you shouldn't have any problems with getting water in the diffs. I believe they actually vent into the air intake somewhere(before the filter), so if you have a snorkel you can even go right under without getting water in the difs.
Gotta love how water proof the mogs are.

Reg trucks like mine usually have the difs vented along the fram rails, so if you get water up that high you should change the fluids.

if you place you diff breathers high enough so that water can't get in it should be fine.

As long as your axle seals are all in good condition...

Then there is the breathers for your tranny and transfercase, and if your computer sits kind of low you might want to seal that up, and the ignition system etc...

Those breathers also vent up under the hood on mogs. I also believe in the air intake. the ignition systems on mogs are completely water proof. As long as the air intake is above the water the thing will keep running.

Don't forget the distributor breather (not necessarily on a Mog but other trucks).
