Stiff power steering

[coffeedart67]

Rebuilt the power steering control valve, new power steering pressure hose, and now my steering is stiffer than it was before. Before it was the typical light, oversteering chrysler steering. This is on a 67 Dart GT with 273 2 barrel automatic. I would prefer the light steering. What do I try form here? Pump? Can't really afford a new box right now.

Thanks

The pump is spinning at least at idle and reving it up, drove 18 miles to fill up with gas and didn't hear any squeals that would indicate the belt slipping. Will a pump quit pumping but still spin?

Are you talking about the spool valve in the pump or the valve in the box?

The valve on the steering box.

Should there be front to back play in the powersteering pump? I can move the pulley about an 1/8 of inch, forward and back, it is the pulley and shaft that are moving.
