[Longhorn Man]

before you go tuning the wheel on the column, you need to see if the gear box is centered. (basicly what wideside said)
With the wheels straight ahead, count the turns of the steering wheel from center to lock, then, from center to lock in the other direction.
If it is the same abount, then you can pull the steering wheel and adapter off the column (the large center nut in the adapter with a steering wheel puller, then install it centered.
