I went with the All Ford Gear Oil & Modifier.crow magnum said:i was wanting to change fluid and was told by a ford mechanic.that i should use ford productds including their modifier..i was thinking of amsoil products. any input?
Dyno Don said:Crow Magnum ( great name by the way) - Using Ford fluids in the rear does one thing - it eliminates ANY problem with warranty work on the rear end gears. Using anything else may, depending on the dealer, give Ford a reason not to honor it.

I was looking at the paperwork and it was recommended I change the fuel filter, well ok, but also that the rear differential fluid was found to be dirty/contaminated and needs to be changed. Huh? I found it in the paperwork - they never said anything or tried to sell me the services but somehow I find this hard to believe, at 33K miles???
Ok, I'll do it then. Next oil change. Thanks Terry!tigerhonaker said:Lynda,
