Steering wheel not straight

There are only two ways outside of an accident/bent parts problem on a new large chassis vehicle that a steering wheel can be off center. Tie rod ends need to be adjusted and the toe in reset. The other way is that the steering wheel was installed a spline tooth off but that may be impossible with that chassis as there may be s blind spline which only allows for one way to install that wheel. Any large vehicle alignment shop can correct the off center wheel. If it's a smaller vehicle, a rack and pinion type steering gear can be installed not centered. This can be easily checked by turning the front wheels lock to lock via the steering wheel. If the wheels don't turn as far in one direction as the other, that R&P need to be adjusted - and that is, again, via tie rod end adjustment. If it's an "elderly" higher miles vehicle, there are several more potential parts contributors

To the OP, it is probably more annoying the a problem but don't guess - take it to someone that is familiar with these chassis - a Ford dealer or a truck alignment shop. If it's new, no big deal. If it's an older vehicle, be prepared to spend a couple hundred bucks plus on an alignment and maybe a few replacement parts.
