While thats true, the OP is looking for a reason that the truck now behaves
differently. This also does not explain the pull to one side or another.
IMO, he needs to find a better alignment shop, since going in a straight
line the truck should not be subject to any geometry influences.

Well, I figured it out today. Boy, do I feel like a dumbass!
I somehow got confused and installed the drag link backward.
I laid on the ground this afternoon and looked at it for a long
time... Fortunately, I had taken a couple of pictures of the parts
laying on the floor.. I remembered the tie rod ends were at a ninety
degree angle to each other when I removed the old link... with the
drag link backward, the tie rod ends were in the same plane... i
gently removed the parts and re-oriented the drag link. The mofo is
golden now. No scrubbing of tires, no binding.
Honestly, I haven't ever seen a suspension that would work with the
parts in backward. The alignment guy must not do enough of this type
of front end to notice the difference. It "looked" right. Now it
feels right. I am so glad!
Thanks for your responses. I learned about the ackerman effect, which
is ultimately what led me to realise my error of installation. I'm
just glad I didn't ruin the tires in the process or bend anything..
It's hard to admit when you screw up.. might as well do it on the
internet! LOL
