Front diff breather spitting oil
I changed the fluid in the front differential this weekend and cleaned out the breather hose as well. The service manual states it takes 1.83 quarts and I got about 2 quarts out of it and it was pretty dark.

water in heater/blower housing and on floor after carwash
I'm not sure I fixed the water leak issue but the rattle is gone. I ended up replacing the Cowl Plenum drain valve 15040083 on the passenger side. I didn't take a picture but if you enter the part number into gmpartsdirect you'll see where it goes. The rubber part of this valve was torn away... -

I have taken the breather out of the differential already. Large plastic piece that threads into the housing- Blew compressed air through it and brake cleaner and the breather assembly was clear and free flowing.

Front diff breather spitting oil
I couldn't find anything searching this forum and tried another GM Truck forum with no luck either. I have a 2002 GMC Yukon XL 2500 SLT, 6.0L. I've been noticing that after driving highway speeds, 70 to 75 mph, there is oil dripping off the frame and the front differential breather is wet and...- 56napco
