ok yesterday my 97 blazer was making a hell of a noise that only showed up while in drive. (turned out to be the cat.)
but while checking around i was going to check the diff fluid..........what the hell is the rubber tube that runs from the place the check plug would be on the diff up into the fram rail?
can ya tell i'm use to the old style's?
fluid..........what
That's the differential vent. There's a hose on it so when off road you don't get water in the differential. That is unless you get in water deeper than the hose.

maybe not in the world of 4x4 which i'm just getting into from street rod'n'
so how do i add and check the fluid levels?
There should be a small pipe plug on the passenger side of the pinion. It is a 3/8" square drive. Clean it out, get an extension and press with all your worldly might into it, while turning it. Then bring it to a plumbing supply store, and have them find you a real plug with a male square drive, or a hex head even better! Then mail that POS plug to GM.
