I just replaced the front steering linkage, ball joints, bushings, shocks, struts and strut mounts. The mechanic who performed the alignment indicated one of the numbers was still red and was unable to get it any better unless he "drilled" something. I don't have the print out or any more specifics since my wife dropped off and picked up the car.

The car drives much better but still pulls slightly and noticed considerably more tension/pull when turning in one direction over the other.

Any idea on what would have had to been drilled to correct this issue or any other additional adjustments that can be done in the future to correct it?

 

Probably the strut tower, to allow more movement of the top of the strut (which is basically the only adjustable part besides the tie rod ends)

Swap your front tires from side to side. If the pull or any other behavior changes, you need tires.
