Do you typically use your computer while laying on your left side? LOL!
Your steering looks pretty decent from that shot.

Not the correct term, but that doesn't matter.

You need to put the jeep on flat ground and have someone sit on your jeep with the engine running and the steering at a full lock turn while you slowly roll the vehicle forward and back to see and feel where the binding is occurring.

What you are describing sounds similar to what happens when people use 4wd on dry ground or if there is a loose/worn drag link or tie rod end that is binding.

Yes! Exactly ( using 4 wheel on dry ground) will give that a shot. Thanks

Never use 4wd on dry ground. You can damage components if you do anything other than drive straight.

Only all wheel drive can be used on dry ground--ie, Subaru.

Wow- figured it out! The damn front tires now will rub the front bumper on a tight turn! Wth? All control arms were measured exactly from teraflexs instructions. So i am assuming i will have to redjust to smaller ?

Makes sense. That would be because the teraflex arms are putting the front axle back in the center of the wheel well. You can shorten the arms, run smaller tires, put on a stubby bumper, or just live with it.

Since your alignment is all dialed in. Another option is to take a grinder or sawsall, or both to the inside of your front bumper where there is a clearance problem. If you still have the modular bumper, you could just remove the ends.

Depending on how much material you'd need to remove and how much you like the bumper, you could still remove material with a flap wheel on a grinder, or you could use a plasma cutter.

If you don't have those tools, your local exhaust shop does.

Ok a quick question- could the front lower arms be shortened a 1/2" and if so- do the upper arms have to be adjustwd accordingly also? Thanks
