Torsion Bar Install
Well, I took the 75 Duster to the alignment shop and they didn't know what to do with it. The caster numbers weren't impressive, but I'm convinced this isn't an alignment, tires, etc problem. I used to align this myself with 25yo components, before offset bushings, with a tape measure, with no concept of caster, and drive it down the freeway at 90mph on air shocks and 20yo tires and I didn't have this problem.
Anyway, my new theory is that the pitman arm is off 90 degrees and the gear box is not operating on center. I don't know why that would have changed, as I never removed it myself and the shop shouldn't have had to take it off, but somehow my steering wheel is 90 deg to the right while my wheels are aligned and sleeves are almost out of threads to work with on both sides.
POA: disconnect center link - turn steering wheel back and forth to find center, hopfully verify that pitman arm is 90 deg off, Hopefully find that it has 4 blind spines, correct the position, reconnect center link. Drive it to the nearest brewery.
