tie rod angle

[texastrendz]

i need the help of some suspension gurus. i have a lot of bumpsteer through the cycle of my suspension. i need a little insight on how a front suspension setup is supposed to work. i have been reading pages and pages of info. the truck is airbaged, from layed out to aired up the tires swing in and out badly telling me i have a bumpsteer condition. is the tierod supposed to parrell with the lower control arm at ride height? i do not know a lot about front end geometry and want to learn. any help would be great.

it is a dual arm with center drag link style front end.
