Calling Wyldman (or anyone else)!!! I don't think I've asked you questions before but was upset to see you go, just in case I needed your help. Glad to see you and everyone else around.
I have a ’97 Ford F250 Heavy Duty with IFS (pretty sure it’s a Dana 50). I want to change the front differential fluid but can’t get a straight answer from anyone what type to use. The manual says “4x4 gear oil”, Napa couldn’t help me out and when I called the dealership they said to use 80W90 without asking me any questions about the vehicle, so I’m a little hesitant to believe them. What is the correct fluid?
