Sorry in advance because this is a really stupid question but now I am super confused and Im throwing myself out there. So I have searched this site and found many different answers and all my shop data gives me even more choices for potentially wrong information.
My diff is leaking. It needs to be sealed and re-filled. What gear oil weight should I use and synthetic or not? Yes I have gears, no I cant remember which brand so I cant check to see if they recommend syn or conv...does anyone know?
So yeah, I know I need the friction modifyer from Ford...but 75-90? 75-140 (which seems crazy)? 80-90?
