This was recently posted by Ford TechMakuloco. Seems a lot of work for fluid change. I will be installing a pan with drain plug with the first oil change @50-60k miles.
The procedure seems fine, but I would still check the fluid level at operating temps. He only checked it when cold.
I started hearing a faint whine that starts at 70mph under any throttle application.
Goes away under no throttle.
I have the fx4 package but it happens in 2wd or 4A.
Anybody experiencing the same issue??
Diagnosing this at the dealer will be almost impossible since it...
