steering problem
 

I own a Mitsubishi Montero model V66W, 4M40 diesel, 3 doors from 2002. I just changed the outer tierods, lower ball joints, sway bar links (stabilizers) on the front. I still have to line out the wheels. It drives okay, but when I turn left and drive straight my steering wheel has an angle to the left, when I turn right, the steering wheel has an angle to the right. Turning the steering wheel does not give me any slack. The transmission to the wheels seem direct.
What could this mean?
