Whats wrong with my Dusters front end?

Tires are 195/60/15 because late spindels and a huge -offset brought tires close to the fender. I dont know about alignment specs but the guy who did it did a great job with my -64 Valiant and my brothers -68 barracuda. And the Duster runs great too, until you turn the wheels in higher speeds... Example: Im passing a slower car at 80km/h, when im on the left lane I have to turn steering wheel to the right to go forward, and again when Im back at the right lane I have to turn steering wheel to get the car straight... :banghead:
Edit: Disc brakes and Upper Control Arm with small joint. Theres a sleeve to shim the small joint to the spindle.
