I have the same problem with my '48 8N.
I was told that only the left side could be turned and that mine hadn't been touched. Also, could only turn it a quarter turn. If it needed turned more it was rebuild time or upgrade to newer steering box.
My steering has about 5-6 inches of play at the steering wheel. The left side seems tight but the right side is loose.
I see some bushings are still available on this site or just8n's site. Which ones will fix our problems?
I'd like to keep the original steering box.
