ORD arms are 100% built right here, about 75 feet from where I sit. Other shops do sell them but they are typically marketed as our arms.
I've talked with one customer that had a problem with a hole wallowing out on one side of a pair of high steer arms. This is Fred Pierce. I also have some looseness in my steering arms but I don't know of anyone else with problems. Typically a wallowing problem is due to the end coming loose a little and the taper getting egged. It doesn't surprise me that this happened on my truck, that was a maintenance point that I ignored till it was too late. I am still running on the arms, I just keep them sucked down now and know that repair time is coming up.
The repair for a wallowed out tapered hole is to weld it up and re-drill and taper it. I have talked to Fred about options for fixing it, mostly revolving around getting the arm back here and working it in with a batch of our arms to repair. One other option that could work is using a repair sleeve, which I just found a good source for. It'a basically a hardened split tapered sleeve that would be put in a through hole. We haven't messed with this one yet so it may or may not be a good fix. It would at least be easier for a guy to do himself rather than sending the arm back to us for repair. I can understand fred not wanting to part with his steering right now since I guess AZ wheeling is just getting going.
The material is not a problem, my arms (our very first) were built from a mild steel that's not particularly hard or strong compared to what we use now. All of our newer stuff is a cold rolled material that's about twice the yield strength of the previous material so the holes aren't going to wobble out on their own. Not knowing what other manufacturers use for material, it's hard to compare ours but I would bet that what we use is as good or better than anything else out there.
Now to the original question.
High steer works well but is only cool for the clearance. And maybe the cool factor. A HD tierod in the factory location works well, is pretty durable, puts less stress on the tie rod ends and is a bit cheaper.
