My local Ford dealer is going to look at the truck on Thursday. There are a small number of people reporting this issue on the Ford Enthusiast Forum. I assume it’s more common if there is now a TSB for it. I filled out a concern form with the HTSA and looked at some aftermarket steering stabilizers. There are not many aftermarket stabilizer kits that fit stock height trucks but I found a kit from Pro Comp that should work. If Ford doesn’t apply the TSB, I’ll spring for $160 for the Pro Comp kit and install it myself.
