a mechanic once fitted balance rod on rear suspension of honda civic 95 in a way that the car used to jump more rather then running. He went through so much lessons about alignment from this incident that he runs a friendly advisory service in Faisalabad
he thought its with camber, casters and what not 
actualy the mechanic fitted the balance rod in inverted direction (changed sides) and he used some help from the big hammer to put it in.
ended up changing the rod and some other suspension stuff
moral:
always get work done from a knowledgable and expereinced fellow
