I wasn’t sure where to post this, hopefully I got the right spot. I am attempting to change my left knuckle on my 2012 f150 platinum. I ordered the oem motorcraft knuckle, but they’re 7 holes that should be threaded that are not. Is this normal and I just need to find someone to thread the holes or should I return the part because this is wrong.

 

This is just a guess but perhaps that knuckle is meant for a 2WD? I only say that because off the top of my head the three smaller holes in the last pic are for the IWE i'm pretty sure. I would have to look at mine later tonight after work to see what the others are for.

 

That was my thought too, I ordered the 4wd one, but maybe they sent a 2wd one. Those 3 are definitely for the IWE, the 3 on the other side are for the brake dust shield and the one by itself is for the abs sensor cable holder.

 

I believe the three small holes are for the metal cover behind the rotor. I think those small bolts are self tapping. That looks like a 4x4 knuckle to me. The 4 large holes are for the hub bearing assembly and the other 2 are of course for the caliper bracket.
