I realize that the various PC models have different alignment issues....some maybe with little to none. But our PC2350 required offset bushings to get the alignment done right. This involves some disassembly/reassembly. It's more than considered typical.
Here is what offset bushings look like. In the picture, the left gold one is slightly off center, the right silver is more extreme. A "Good" truck alignment shop will know what to do if they cannot align the rig working with the stock suspension. Such an alignment is not something a generic tire shop can do, and maybe not for some Ford dealers. I fear some shops adjust it as far as they can then consider it done....good enough.
