Yes! And the hose should have a plastic cap thingie on the other end and should be up high enough so that when you go fording through rivers, that no water will come in the hose

GM didn't include a hose on the breathers in our cars. There is a thread around that someone bought the pieces from GM to run a hose up higher than the breather with a loop in the hose. This was to keep oil and vapors from coming out of the housing though and not to keep water out. You shouldn't be getting water through the breather unless you have a tendency to drive through water that's up to your doors all the time.

ok, no i dont drive threw high water. but when i first changed my rearend oil it was white milky...then last week i loosen the bolt to check the fluid after running about 3 weeks after the change and it was milky again...so moisture is getting in there somewhere somehow..
