So, this hard steering issue, on my recently acquired 29 Fordor, finally reached it's limit and I pulled the steering box out of the car tonight. I had previously removed the drag link from the pitman, trying to isolate where the stiffness was originating. It took a firm pull just to make the wheel turn with nothing attached. Driving the car was a 2-handed affair and very challenging.
What I found was that even though the box had been filled with grease, not 600, for years, every thing in there was fairly free and limber, except for the septor bushing, which was a bit on the dry side. I had been picking out the grease and shooting diesel fuel into the oil hole for the past week in an attempt to cut the grease down to a thinner mixture.
The absolute MAJOR culprit was the WICK within the bushing at the top of the steering column. It was dry, hard and gummy and tight as all hell on the steering shaft. It took a brass drift and a deadblow hammer to get the shaft out of it! The shaft is actually blue from friction contact in that area.
At this point, I'm not going to buy the shortened pitman arm. I'm going to put it all back together with new gaskets and bushings and take her for a spin. Thanks for everyone's input.
