OK I found out what it was!

My friend is a mechanic at a local chevy dealer so I took it up there after hours and we tore it apart. I couldn't get any pictures on my own, but I found some on the net that will show. The front driveshaft CV joint that connects on the T Case end seal broke, so I need a new CV joint. Cheapest I found was about $70 plus shipping.
AND, for the record... my tires ONLY rub when going up a steep hill or popping it up a curb. There is some plastic on the fender wells that shows wear... but that's from when they rub up a hill or whatever. They don't rub while driving or turning. I can turn as sharp as I want and nothing happens. The pinch welds do not rub and they are not banged in or anything.
Believe that or not... I don't care really. Come to Amarillo, TX and I'll show you in person
Here's an image I found that shows the shaft and cv joint...

And the replacement and link just in case someone needs 1 also!
