quick diff/breather question
 

im doing the breather mod soon, i bought a 3/8 nipple but it is too big, i guess i need 1/4. but before i do it i want to make sure there isnt any water in my diff. is there an easy way to tell, or should i just change the fluid?


searched, but could not find out how to check the fluid.

also, how do you check the tranny, transfer, front diff? is it a good idea to extend the breathers on those too?

sorry if this is brought up a lot, but i couldn't find it searching. thx

btt.
