Anyone around here a classic Mustang control valve expert? I'm sorry, but I don't need a lot of advice from a bunch of people who've had a control valve apart at one time or another sometime in their lifetime. I mean a real expert that could help me narrow down a problem I'm having with my 69. For the last 16 years, it has turned to the right slightly easier than it has to the left. When it is cold, it will spin automatically to the full right position. I recently rebuilt the control valve. Pristine cleanliness, everything is tight but slides freely, new seals. I still have the same problem, but it is slightly worse. Adjusting the lock nut at the end of the spool bolt has no effect. I've gone from completly tight to one and a half turns out with no change.

Three things I noticed when rebuilding. Bumper spring doesn't seem to do anything. When tightening the travel regulator, the bumper tightened hard against the ball stud seats. The travel regulator with its stop pin can stop in a variety of different locations. That is, you can 1. screw it in as far as humanly possible without breaking it, 2. screw it in until its tight, or 3. screw it in until the bumper almost bottoms out against the ball seat, but not quite. I did number 2, but wasn't sure it was right. Finally, my centering spring is worn and should be replaced, but that should only make it harder to adjust, not just always pull one way. What I mean by that is, if I were to take the spring out, and tighten the nut all the way, the steering should pull one way. If I back the nut off a few turns with no spring on there, it should pull the other way. With all that said, my question is, what effect would tightening or loosening the travel regulator have? Unfortunately, We will have to correspond by email beacuse I almost never can check this forum due to filters and firewalls at work that prevent me from accessing sites that have the word mustang in them. I'll never understand the filters and firewalls they have at my work.

just me, but if the centering spring is worn out that is your problem, because the centering spring does have an effect when the power is applied, it is designed to keep the steering centered and to keep the car from doing exactly what you are describing. it does not just have an effect on static adjustment. for instance, if your car's alignment is perfect but the car pulls to one side it can be corrected by adjusting the control valve, that is why the control valve is adjustable. if it din't have an effect it wouldn't need to be adjustable. i think you need to rethink what you're saying here. i've emailed this to you as well.
