I went to my Ford Dealer today because I needed to get the rear ABS sensor and while there, I asked the Parts Counter person what the rear diff gear fluid weight was so I could also empty & refill for preventive maintenance (and due to accumulated miles).
I was told the rear diff takes 75/140 - is this correct? If it is not correct, what is the proper gear fluid that I should be using? The Ex is a 2004 4.0 w/ 4x4.
Also, if draining out the old fluid and putting in the new fluid, do I need to put back in Friction Modifier or not? I know on the Mustangs (8.8 rear w/ traction lok), those do need Friction Modifier in addition to the gear fluid.
Thanks fellas!
