Do yourself a favor and upgrade to the Timken bearing for 10 bux more. Never had good luck with Ford bearings, especially when lowered and/or driven on the trackJust did it, for anyone in the future looking for an answer, the front axle nut is a 35mm, torqued at 251 ft-lbs
Axle nut part is FR3Z-3B477-B
Hub/bearing is FR3Z-1104-A / MOTORCRAFT HUB-284
Didn't even need a tool to remove the hub, it was very easy.
