Well 6° of caster is in the ball park for good handling , I cant remember the numbers on pinion ....even that pitman arm could make it wag its tail I suspect.Well like i was saying, its sits so high that my control arm angle is severe. Iss it possible that i have my pinion angle so releaved that its allowing it to move badly? Maybe i should adjust it more so that my springs r not bending and possibly creating that rear movement?
