Whats the rear differential capacity for a 2500HD Yukon XL? It has the limited slip option and the 8.1 liter if that matters. I have series 2000 Amsoil that i'd like to change it over to and was curious so i don't short change it or overfill it. My father will be towing our 11,000 boat from the keys to NJ in a month. Any help would really be appreciated. Thanks again everybody.
