Home built suspension lift
#11
Anyways, thing off all the suspension parts linking the frame/steering/diff as lines making arcs as the travel up and down (looking at them from the front of the vehicle). With factor suspension they are designed to all arc inwards during upward and downward travel. Although they arc at different rates due to length differences (dynamic camber) they allow for proper steering alignment and optimal ride quality and control since they are all parallel. If the tie rod is angled and not parallel to the control arms, it will push/pull the knuckle against the tucking action of the control arms because it will arc out for a bit while the cas are already arcing in causing the wheel to steer outwards/inward. This is why it's called suspension geometry. This causes dangerous amounts bump steer especially once the sway bar comes off. Check out projektdortfab's heim steering mod thread and it will make a lot more sense.
That's why it's so damn important to offset all mounting points the same, excluding the CV joint as it's length changes by plunging and does not effect steering anyhow.
