Happy new year all, got a 1994 PS 7.3 F-350 4wheel. It has 330,000 on the clock,but is a good rig for my needs. Trouble started a couple weeks. When I'm sitting or moving slowly,it turns great to the left, but to the right it's "Armstrong Steering." Fluid in P.Steering is normal, and I rebuilt the front end 30,000 ago. I did not replace the steering box. The steering wheel itself seems to be solid,no catches,up and down movement that might indicate bearing issues. Going down the road, the steering is good. Any ideas? Any body else run into this problem?
