Power Steering Valve Springs
I have heard that there are two different tension springs in the power steering control valve depending on the year of the application. I do not know if this is true or not. I have also read that many vendors don't know what the valves they sell have as far as springs.
I have a 73 which has been completely restored. All (I mean everything) of the steering components are new or rebuilt. My car seems to kind of stick somewhat when you turn the wheel at the center position. It works but it seems to work all of a sudden and not so much with a light force on the wheel. The alignment is good (twice). I'm beginning to wonder about the valve causing the issue. with the front jacked up and the engine off even the slightest turn of the wheel results in movement. It just acts wired when you are driving.
Any information on the valve spring would be helpful.
Thanks

I set up an inline gauge on mine to make sure operating pressures were correct. As far as spring ratings i cannot help you, sorry. Good luck.

It could also be that the adjustment screw/lock-nut on top of the steering gearbox is a bit too tight. Hold screw in position with screwdriver; loosen lock-nut; turn screw 1/4 turn CCW; again hold it in position with driver; and tighten locknut. If that frees-up your steering, leave it alone. If that didn't change anything, put it back where it was and send a PM to Jim Shea requesting his help.
