There seems to be some confusion about how much oil should be in that rear end. I know its 10 ounces of SAE30w oil for the ones that have the angle check/fill plug, but it is also listed as 40oz in some of the books for the straight up and down check/fill plug. I was thinking I was told the 40oz is wrong but I don't know for sure. I guess the easy way would be to fill it up till oil comes out the the check/fill hole. They call for changing the oil after 5 years and checking it every 300 hrs.
