frame roll help!!!!

need help please!!!!

This is my first time doing a 4-link. i found a article online that seemed to make since to me. I set my bottom links to be level and parallel with the ground at ride height. "4 in. off the ground", the top links are 2 in. less on the x member then the axle at a downward slope. all the bolts are over each other.

when i lay the truck out, the axle is moving 1 in. forward in the notch, and the pinion angle moves a little more then 3 degrees. I'm pretty sure its something simple, but i cant find anything that deals with this problem.

Any suggestions or help would be greatly appreciated.

Your upper bars being shorter and the downward slope is the cause of pinion angle change.

The overall length of the bars is the factor that makes the axle move in the notch.
