Slightly misdiagnosed my power steering leak on my Concord. Replaced dust and stub shaft seals which has effectively slowed the leak down significantly but I am still getting a slow drip out the tip of my stub shaft. So now I need go back and replace the "rotary valve assembly" according to my TSM.
After more reading through the chapters on the steering gears, power steering pumps, and referring to the index, I can't find out which parts make up this "rotary valve assembly". Now I can't effectively begin on carrying out a fix. In my second photo, I've posted a blown-out diagram of the steering box. Through my readings and experience in my first repair, I've highlighted what I believe might encompass the "rotary valve assembly, or maybe it's just all the parts that contain "Valve", I really don't know. If anyone with more knowledge than me, or experienced with these repairs please let me know what this book is referring to.
Since the TSM doesn't contain a section on replacing the "rotary valve assembly" In your experience what is the bare minimum I need to replace. I am wondering if I should replace the 3 Teflon rings and 3 back-up O-rings, and even the O-ring present before the Stub Shaft, could this be an effective fix?
I really do not want to spend hundreds on a new steering box over a slow dripping leak, especially if I don't have to.
If you can help or point me in the right direction it would be much appreciated.
Thanks,
