I just changed out the front and rear diff with Mobil 1 75/90 on my 03 2500. My rear only took 3 3/4 quarts and the front to like 2 1/2 quarts. Is this right I went to about a 1/4 inch below the drain hole. If i add another quart to either diff it will start to flow out. I also measured the used oil and it was roughly what I put in.

 

if it starts to flow out, you have plenty

Hope this is not too confusing, but It won't let me post the nice graph thing in the manual and this is how it turns out when I try...
