Steering mechanism troubleshooting #2

I received this report from a friend that had bought a few cars from me (all Danburys)  I sold him a Franklin Corvette and he said the steering wheel /lower wheel synchronization was intermittent.  I offered to take it back and he said he would try a fix.  Here is his report on getting it “working A-oK”

🤷‍♂️ Thoughts from the experts on this?
