i keep thinking im right on something but it just doesnt set right. on a metric car once you get your lower arms level like they should be or at least i have always been told. shouldnt your tie rod ends be level to. I am talking about a start point before i start to adjust everything. this is a new car. all of the parts came off of junk yard cars. is something off.

The Tie Rods and Lower Control arms must move in the same arcs. The difference in their arcs is " Bump Steer" If the lower control arms are level (good starting point) the tie rods would also be level if their inner and outer pivots were equal.This would result in very little bump steer. Just because both are level does not mean it's right. It's all in the different arcs the pieces scribe as they move. If you mix and matched parts from a wrecking yard you just need to quantify your bump steer. This measures the amount of toe change as the wheel moves up or down. There are 6,587 articles in magazines on how to build a checker, many race parts places sell em too. Basically it's a frame that you can mark vertical travel of the wheel and a dial indicator front & back of the wheel circle that measures toe change.
