The wobbling was so bad with the original control valve in the kit that it resembled that all the lug nuts were loose! When the second control valve was installed, the wheels now only wobble when making a turn, like going around a corner. The wobbling is very noticeable but not nearly as bad. I'm inclined to agree with you that the second control valve assembly is defective as well.
Since the wobbling was somewhat improved after the second control valve was installed, that could indicate that the control valve piston is sticking in the valve body bore.
The
power steering control valve is easy to rebuild and you do not have to take the entire assembly off the car to do it. The
power steering valve body can be rebuilt by removing the center valve body section only.
Start by removing the
power steering hoses from the control valve body. Next, remove the two screws from the end cap and remove the cap.
Remove the nut, the washers, the spring and the spacer in the order they were removed.
Remove the two bolts that secure the valve body to the ball stud housing tube and remove the valve body from the housing tube.
Disassemble the valve body by removing the sleeve and large washer, and then push the piston out of the valve body.
Check the holes in the piston to insure they are open and fluid can pass through them. Also, check the piston to insure a smooth surface, then lubricate the piston with
WD-40 to insure free movement in the bore.
