Gang, At 65,000, I plan to dump the axle fluids again [+ Trans & XFer Case] (they all will have about 50K on the fluids). I also plan to install a Mag-Hytec cover on the rear axle--it has a nice dipstick and it effectively doubles the fluid capacity. I am going with Amsoil 75W-140 in the rear and 75W-110 in the front. Silly question, but would I also need double the amount of Ford Friction Modifier in the rear axle? TIA for your thoughts...
