Adam is correct...if they are not leaking no need to replace...what I did to adjust is I took the cap over the adjustment nut off and drove it to see which way it pulled and would stop, turn the steering wheel as far right as possible to get access to the adjustment nut and make a small adjustment and would drive it again and repeat until it stopped pulling...make sure you turn off the engine before adjusting. If you should adjust it too much the steering could violantly swing the other way and hurt you while your arm is in there...TURN THE ENGINE OFF !!!!!!!

The problems with the steering control valve and my steering box being worn, is it what convince me to put the steeroids rack and pinion on Mine. I went through 3 control valve in the 12 years I have owned my 77. You should be able to jack the front up and adjust the valve for centering. if you have to make further adjustments, i would say the valve is defective. I would replace the control Valve.

Is their not a pressure releif valve on the power steering pump to keep the pressure within limits, if someone replaced the power steering pump their was is fittings that need to be transfered.

IF the valve is out of adjustment, then yes, correcting the adjustment will cure the tendency for the car to dart, and the wheel to turn by itself.

It will not stop a leak, tho.
The adjustment is under the metal cap on the end of the valve, similar to the dust-cap on the front wheel hubs, where the bearings are. I'll see if I can locate a decent pic...

Please read thru the above linked threads for the procedure, AND the safety cautions!Adams' Apple2009-04-13 20:06:10

After reading this post I went and looked at the spot where I store the Vette looking for possible engine oil leaks. Well no engine oil but a nice puddle of PS fluid was there. Got her up in the air and there was fluid leaking out of the control valve dust cap. Got a valve, popped it in, and I didn't even have to adjust it. Man I tell ya, I had no idea how bad that car was steering until I did this.

Thanks for postin Dave. This thread told me just what to do.

a good web site

http://jimshea.corvettefaq.com

The control valve must be adjusted after being disassembled as outlined in the following procedure.

1. Install the valve in the vehicle, but leave the dust cap off. Connect all hoses and fill the pump reservoir with oil. Do not connect the piston rod to the frame bracket.

2. With the car's front end off the ground, start the engine. One of the following two conditions will exist:
A) If the piston rod remains retracted, turn the adjusting nut clockwise until the rod begins to move out. Then turn the nut counterclockwise until the rod just begins to move in. Now turn the nut clockwise to exactly one-half the rotation needed to change the direction of the piston rod movement.
B) If the rod extends upon starting the pump, move the nut counterclockwise until the rod begins to retract, then clockwise until the rod begins to move out again. Now position the rod to exactly one-half the rotation needed to change the direction of the piston rod movement.
CAUTION: Do not turn the nut back and forth more than is absolutely necessary to balance the valve.

3. With the valve balanced, it should be possible to move the rod in and out manually.

4. Turn off the engine and connect the cylinder rod to the frame bracket.

5. Restart the engine. If the front wheels (still off the ground) do not turn in either direction from center, the valve has been properly balanced. Correct the valve adjustment if necessary.

6. When the valve is properly adjusted, grease the end of the valve and replace the dust cap.
