You will probably need to replace the fluid as its suppose to have 75/140 synthetic in it and not 80/90..
if you are going to work on your own stuff.. LEARN to get the correct information, then purchase the correct stuff. and do the Job ONCE.
CHEAPER that way.
Look at your rpo sticker in your glove box or wherever it is to find out what it came with or look on your diff pumpkin an read the tag. Then call ford and ask them that way you'll know just what to put in there
