Knuckles on 4WD and 2WD the same?

I just installed a Superlift on my '04 FX4 Level II and am wondering what to do with the old knuckles. Would they function to help lift a 2WD model or they the same? I'm wondering whether to trash them or sell them.

the 4wd knuckles will fit on a 2wd Edge ONLY......since the 2wd Edge has the same suspension as the 4wd Rangers...

When I did my superlift my knuckles had a big hole in to midle for the CV's which would mean they would not be able to mount on a 2x4, unless the spindle seperates from the knuckle.

They will bolt up to a 2wd, but you would also need the 4wd hub and rotor to be able to bolt the wheel on to it. Even then its not safe to drive on it without a CV shaft going through the hub.

OK, I finally did what I should have done to begin with, I dragged out the 10 lb. Ford shop manual and looked there. It identifies the 4x4 part as a "knuckle" and the 4x2 part as a "spindle". They're not interchangeable and they look different. As Doc said, the 4x4 part has a large hole for the axle half-shaft to pass thru whereas the 4x2 part has a large shaft for the wheel bearings, etc.

Thanks for the help.
