I have come across several newer ford pickups with milky fluid in the front diff. I have done a search on google and looks like some are saying this is just the fluid Ford uses, others say it is water in the fluid. Anyone ran into this. It is a pain to change the front diff fluid, but have been doing so. These trucks have low miles and don't leave the pavement.
