Steering is eradict and jerks. Not good when using the forks and trying to be gentle. Adjusted the linkage according to the manual using the 3/8" and 1" spacer. Made it worse. Whats next?
 
Are the alloy blocks on the pintle arms from the pump tight? They can get loose and wollow out so you tighten the bolt and it still will not hold the piltle arm tight.
Lift the cab, get a screw driver and see if you can lever the alloy arms on the pump up and knock them down. If they move, tighten them, if they still move, they need replacing.
I have an S250 that had this exact issue. It was jumpy, there was no way you could do precise work with it, it would be going slow then all of a sudden jump forward at higher speed.

I will check. One thing i did notice is when looking at right side pintle, looking from front, without the spacers in, the rollers do not touch the block under tthat bracket. The rollers also do not roll, which I know they should. I just need convinced this is a linkage problem and not some kind of hydraulic motor problem.

It doesn't sound like a hydraulic problem to me, but you never can be 100% sure on that.
The rollers should touch the stopping bar, you will needt ot adjust it so they make good contact. Not all of the machines had rolling stops too, some were just round bars, the rollers didn't wear as much.
