It's easy enough to fix if you're moderately handy and have some spatial relations skilz... (your alignment guy should be responsible for getting this right, but in lieu of that do the following
If the wheel is off to the left, visualize this:
1) Straighten the wheel (turn to the right)
2) Your wheels are now pointed slightly right. You need to pull them back to center
3) Loosen the locking nuts on the 2 tie rod ends
4) On the left side, turn the tie rod
IN 1/2 turn (clockwise)
5) on the right side, turn the tie rod
OUT the same amount ((counterclockwise).
6) drive to see if straight, tweak from there. Be sure to make the same changes on each side and you're alignment will not be affected. Be sure to tighten the locking nuts when done.
Wheel off to the right, do the opposite.
I've done this many times and had to do it on my Z as well. Being slightly off drove me crazy!
