No bellows don't let air out from the diff they only allow room for contraction & expantion, hence the name BELLOWS, they are sealed!

 

ahhhhhhhhh

 

AHhhhh is right, If your bellows leaks, FIX IT, ITS BROKE !!!!!!!

 

the diffs should be able to be submerged all day with no problem. Check the bellows to be sure they arent cracked and maybe take them off and silicone where the slide on the spigot. The oil level is close the axle seal but the constant churning when running would have the oil leaking out in no time.

 

nothing leaks out it just gets in.and i checked it yesterday and it seems ok now.no water in the oil. and i've bin in lots latly, just see my new pic's, that just part of what i've bin through in the last few day's

 

what's up wit this yfz BS.
