Hey all,
I am seeing some conflicting information on this and was looking for some input.
I just changed out my rear differential fluid on my 2003 Ford Explorer Sport XLT (8.8 rear end).
The manual says to fill it between 5.5-5.8 pints (2.75-2.9 quarts) as well as adding a friction modifier (4oz/0.125 quarts).
My father in law told me to fill it until it was dripping out of the fill hole. I only had 3 quarts of the Motorcraft 75w-140 gear oil and the 4 oz of the friction modifier. I added all 3 quarts and the 4oz of FM but did not see it dripping out of the fill hole.
I stuck my finger in the fill hole and found the level to be pretty close. I see some people swear by the manual's amount and leave 1/4" from fluid level to fill hole while others swear by filling it entirely until it drips out.
I am kind of in a jam and can't get my hands on any gear oil this weekend and was wondering if what I filled my differential with would suffice or if I should worry? Thanks in advance, guys.
