Sounds like you hooked everything up without initially centering your servo.

I also like to adjust the turnbuckle between the servo arm the ackermann to make sure the car is perfectly centered, I don't use any trim setting on the radio when initially setting up a car to go straight. Also make sure the lengths of the turnbuckles on the steering links are perfectly equal, use a caliper to check length.
