Not sure as to what you mean by turning the wheel (sitting still or driving). You may want to check and see if you have the springs in their seats on the lower control arm and upper cup. This my give you the "feel" your getting.
I would also recheck the ball joints to make sure their tight. How long has it been since any front end work has been done?
With making the changes you have made, you may want to check out the tie-rod ends, idler arm, etc.
