Hey everyone, today i replace the rear diff in my wife’s car. The ATC (Automatic Torque Coupling) splines were stripped. This means power going in to the diff is being applied by the car, however no power is being transmitted to the rear wheels as the spline is stripped. Sadly a new diff is required as Ford does not sell any internal parts.
This is a brief replacement video and a quick How To on the computer programming of the coupler.
My differential came pre filled with oil, however it seemed “milky” and had a very odd texture that i was not OK with. I drained and re filled it with good quality 80-90 GL5 rated.
I encourage people doing this job to check the oil.
Enjoy! Hope it helps.
