Yes.

The upper control arms bolt to the crossmember with 2 nuts on each side.
The lower control arms bolt to the crossmember with 2 little u-bolts per side.

You can either leave the crossmember in the truck and swap everything from there out, or you can take the whole crossmember as an assembly, leaving all of the arms and stuff in place, and swap it in complete.

It's your choice, but myself, I prefer to leave the crossmember and swap all of the later stuff onto it. That way, the engine stays right in place without having to support it with a hoist while the crossmemember is out of the truck.

I hate having a jack or hoist in my way when I'm trying to wrestle that big, heavy, cumbersome front crossmember in place. I rather like to do each side seperately, it's much more manageable, and no jack or hoist in the way.

You'll use the steering stuff too, as well as the steering box off of the later donor if you'd like.
