It would probably take some time to see the effects of rubbing on the spring, maybe some duct tape on spring would show itself. Other than that, I've seen where tie rods weren't torqued to specs causing a clunk.

If its the spring what can be done?

On my Dodge, I did my lift in multiple stages. 2in level, 3in level, all the way up to 10in of lift. I thought when I went from 2 to 3, the alignment looked alright. I didnt take it for an alignment. I had a horrible clunk, and when I took it in the alignment was pretty bad off on one side. Im not sure why but it went away after this.
And like I said previously, if you are getting metal on metal contact you will see it. It will look like someone polished it wherever you are getting contact. There is no mistaking it. Still, generally when you have the clunking after a level its either a bolt that has been under/over torqued, the spring seat not being in the proper position, or of course steering problems

Easy test is to jack up the front of the truck on drivers side. If UCA comes down enough to contact spring, then that may be it. AS touts that as the advantage of their offset spacer design (to help avoid contact between UCA and spring). You can also push in/out on top and side of tire and see if you can duplicate the clunk. Take a look at your tie rod ends while you have it in the air.
The autospring spacer instructions recommend re-torquing everything after 500 miles. You could just swing by dealer and have them re-torque everything to see if it goes away.

I'm going by the Ford dealer Monday morning, what should I have them look at beside the tie rods being re-torqued?
I'd really appreciate everyones opinion on this so I can pretty much hold the dealers hand and walk them through this. God help me if they give me the ole "can't duplicate" line, I'll make sure I take the tech for a ride and make sure he hears it....I'll duplicate it for ya lol

The most common clunking issue I've read about after a level kit/strut install is sway bar end links not being tight enough.

Any idea what causes this? Saw no signs of the springs hitting the UCR...I've noticed this knock before but not as loud...judging by the groves and the fact that my 5100s have been on for a week I think it's safe to say its been happening for more than a week

From the markings on the crossmember it appears that one of your LCA bolts is more outboard than it once was. Maybe the bolt was loose and it reamed the hole bigger from moving around? The bolt should fit snug in the hole and not be able to move inboard or outboad unless the hole somehow got oblonged.
