Might be a long shot, but...

How did you adjust the steering box? You must make sure it is
On center first by driving straight ahead at least 10 ft. Then loosen lock nut while holding set screw at same time. Back off
Set screw about 1/2 turn. Now tighten set screw LIGHTLY till you
Feel resistance. Now hold set screw in this position while
Retightening lock nut. Like honky Kong said before , it will be all over the road, fighting it.

I’ve got the steering box where I want it now. Truck does have a serious toe out issue, too. But, I’ve got to get the driver side lower a arm replaced first

Why are the lower control arms such a hard thing to find? I can find the uppers anywhere, but LMC is about the only place that has them. Rock Auto is out along with about everybody else. Since mine was tack welded, what are my options in getting it fixed w/o replacing?
