Sunday am. before the start of
Supper Bowl 50
Remove and replaced the NVC3 3500 differential oil @ 60,350mi.
First I took the van on a 1hr highway loop to warm the oil; the diff. felt warm to the touch. l wanted to capture the first oil out; was slightly surprise at the velocity it came out, .. probably over filled the small bottle times 2.5 or 3 . Captured 9.5oz of dark brown used gear oil.
Let it drain about 1hr.
Crawled under the extended; getting ready to fill but I can't locate the drain plug, not on the 14mm Allan;
about 20 minutes of soul searching, asked the dogs, contemplated buying another, thoughtfully remembered unscrewing the plug: ... It's in the small sample bottle!
The fill hole stipulates the correct oil level, ... provided that the vehicle is (level front to back & side to side).
Crawled back under, proceeded to fill the diff with Mobil Delvac Synthetic Gear Oil from a 1U.S.Gal/3.78L container.
It took 2.28L or 2.41 quarts to fill.
Then after a 10mi. + round trip drive to dispose of the used oil, l crawled back under and pulled the fill plug and got what I wanted ; a slight clean weep from the fill hole.
