[BIG BLOCK JIMMY]

Tires/wheels came with the truck. Tires are the same and the wheels appear to be the same, but if I have to I will have them removed to measure.

I'll have my wife turn the steering wheel while under it again, in case I missed something before.

I did check the steering stabilizer tightness and it was good. I thought about taking it off, just for the "why not" sake of trying something.

I'm going to get the toe-in and caster adjusted as suggested as quickly as possible and will rotate the tires just in case a tire is bad (highly unlikely).
