Since he purchased the complete power steering kit from Larry's, I would hope that the pump output pressure matches the requirements of the control valve.Check you pump pressure to make sure if it's in spec. and not to high. This old system runs much lower pressure than todays systems. If the pressure is to high, the control valve can't handle it and will over react making the valve move back and forth rapidly, hence wobble.
Thanks, Larry's agreed with the 900 my pump generated. Larry's is working with the builder and is trying to resolve the problem. Latest guess is that I will be getting a 3rd control valve!!!!!! And just think, this conversion should have been little more than a plug and play exercise.The Ford shop manual chapter 5 page 15 says normal fluid pressure is 700-900 psi
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. Look at #13 posting of this thread.I’m glad to see you have resolved this issue.
What was causing the wobble?
I’m curious because I’m in the process of rebuilding the steering box and valve in my 55 and would like to avoid this.
Sorry for the slow response. In short, it was the control valve assembly. Rebuilding 60+ year old parts (Bendix) is not a science. I never got a response from the supposed 'best' rebuilder around but, after installing the third control valve assembly it works just fine. NO more wobbling wheels. I let myself fall victim to the suggestions of T-Bird parts supplier to have both the front end and gear box completely rebuilt. Turns out it was NOT necessary. That was about a $3,000 unnecessary expense! Did the parts supplier even offer to cover a portion of the costs of their suggested but unnecessary rebuilds - NO.I’m glad to see you have resolved this issue.
