Typing this all out could get complicated sounding though it's simpler than it will sound. The key basic thing is determine "squareness", done by diagonal measurements from fixed, like located, points. To make this less complicated it would be helpful to know three things.
Is the four bar a parallel or triangulated style?
Have you ever done a 4 way alignment?
Have you followed the car down the road to notice if it runs straight or like a dog?
