Question about 1966 Ford Mustang

1 Answer

1965 FORD POWER STEERING CONTROL VALVE

POWER STEERING WORKED GOOD BEFORE I REBUILT THE CONTROL VALVE. THE BALL AND CUPS WERE WORN. NOW IT PULLS RIGHT. I HAVE A REPAIR MANUEL AND EVERYTHING IS PUT BACK RIGHT. THE ONLY QUESTION ON THAT IS THE SPOOL VALVE IS A BIT DIFFERENT IN ONE END AND IT WILL FIT EITHER WAY. I TRIED IT BOTH WAYS AND IT IS HARD TO STEER TO THE RIGHT ONE WAY AND PULLS RIGHT THE OTHER WAY. FOR SOME REASON THE SPOOL IS NOT CENTERING PROPERLY. ANY IDEA'S. I HAVE REBUILT SEVERALVALVES YEARS AGO AND HAD NO PROBLEMS. I TRIED TO ADJUST THE SPRING SEVERAL WAYS AND NO LUCK. I TORQUED THE SPRING TO 100 INCH POUNDS AND BACKED OFF 1/4 TURN. MIKE

    i put dics brakes on front of 1965 Rancharo and the steering went wild. Steering is real sensitive and at higher speeds (50+) it is hard to keep car on the road.

    obviously then, there is an internal spool problem.

    Does it move freely when disconnected? Did you check for burring or spool wear/damage while apart?

    Simply Taking apart and putting together should not cause it to malfunction in only one direction.

    I would suggest disassembly, and checking extremely close with inside mic's and calipers on the sppol to check for damage once again. Any slight variance to the tolerance will cause the valve to not operate properly.

    Where did you get the torque setting from? Do you have a manual?

    I was under the assumption that adjustment was only used to correct oversteering?

    Air in your system will cause the symptoms you are speaking of.

    Was it bled properly?

I had the same problem w/ my 65 Falcon. I adjusted the control valve a few different ways and it made a little difference. I noticed the boot for the ball stud was off-centered and was pushing the ball stud(along w/ the spool valve) to one side. Try lifting the front of the vehicle, loosen the boot strap, center the boot strap and road test the vehicle. I know it sounds like a long shot but it made a difference. My steering still isn't perfect, but it's alot better. Maybe it will work w/ your concern, it might help me figure out what's wrong w/ mine. Let me know if it helps.

1966 Mustang power steering problem


Try tightening your spool bolt. Take off the spring cap, tighten the adjusting nut till it is snug, then back it off no more than a 1/4 turn. Hopefully this will help. If you need a diagram, let me know. I have a shop manual that shows all..

Power Steering Schmatic


Not exactly know what you mean. Could you explain the problem in a little more detail? I own a 68 Mustang and restore, build early iron Mustangs for other customers. Are you using the "old school" power steering system with the ram and valve? Let me know. My email address is tiqautoperformance@live.com. Our website is www.tiqauto.com
