re: "someone directly said several times early on that they were a delivery driver to several automotive shops and that this person had witnessed five or more shops physically remove the steering wheel and reposition it."
This is a no no. The steering wheel and the splined shaft that it is set on have alignment marks. When the steering wheel is at center, the steering mechanism is on what is called the "high point". This is a real physical condition inside the steering box mechanism in which slack or lash in the system is minimum because of pressure from the recirculating ball bearings. (It is actually noticeable by a slight increase of the steering wheel's turning resistance as it rotates through the null or center position.)
Adjustment at the tie rod ends is he correct procedure for adjustment of steering wheel center (along with toe).
