So, I was told by the owner that all it needs is an alignment. I believed him. DUMB, I know. So, I get the car aligned using Steeda camber caster plates. However, the car still violently goes off course when it hits a different groove than the one it is riding on. I'll be on the middle of the road and a different layer of pavement splits the road in half and the car will slip into the groove that catches one of its wheels. On straight and level roads it drives fine and smooth until...Any words of wisdom. Thanks...P
