FLUID FILL LEVEL PTU
My wife's Edge is having some road noise that sounds like a wheel bearing but upon searching I am concerned it might be the PTU.
Car details: 2012 AWD, 45k miles
I sucked out some of the fluid and it was black. Did not get much out despite my best efforts. Pushed in new, pulled out, pushed in, pulled out, etc. The fluid now looks more like coffee, a little translucent instead of pitch black.
I see on here the 1.5" to 1.75" fill level using the zip tie.
However I looked up in the Ford service manual and it says to fill to bottom edge of fill plug.
This seems like a significant difference.
Can someone tell me where the zip tie fill method came from?
Has anyone had an issue filling to the bottom of the filler? It makes me more comfortable having a little more.
