Would've thought Ford would have the A-10 factory fill thing figured out by now. Deceided to check my new one today as the lift was free and I just came in from about 35 minutes at highway speeds. This one is easier to check than the mustang thankfully. Nothing on the stick! Guess I'll give them a call Monday and maybe they can top off the rear axle while their at it, It's down about a half inch. Spec is 6mm below threads.
