Anyone use a Power Steering Pressure Reducer?

The original Factory Service alignment specs, and most alignment shop prob follow those, have the Caster set at 0 to neg Caster.
Your local market shopping buggy's front wheels have neg Caster, ever seen one whobble back and forth and chuckled !
That's what your front wheels want to do if the alignment is set to factory spec.
The new radial tires and modern driving styles suit the Spec on the Skosh Chart, this will give your vehicle better directional stability, and a steadier wheel, especially at speed.
Incorrect Toe will have a tendency to "dodge" left or right as the weight transfers from one front wheel to the other, each aimed differently.
We're it me, I'd make sure all the components are right and tight, then aligned to Skosh spec, - then, if you find fault, - mess with the pump, cuz the positive caster needs progressively more effort/work as you add more caster .
I applaud your desire to "get it done", good for you .
Good luck.
