'70 Power Steering Problem
I have a '70 350/350 with a power steering problem. When I start the car, the wheels turn violently to the left. I have rebuilt the valve, replaced all the hoses, and replaced the fluid. I have not touched the cylinder so possibly that is the problem. I drive the car now with manual steering and it drives fine so the problem is definately related to the power steering components.

I've had that happen to my '70 when I was attempting to rebuild my PS. It's been about 15 years, but I believe there's an adjustment on the valve you could look at. Check out the GM Chassis Service Manual.

Thanks for the comments everyone. I forgot to mention that the steering problem developed before I touched anything (strong pulling to the left). The problem developed gradually, becomeing worse with time. I rebuilt the valve and replaced the hoses thinking that I would fix the problem but I didn't. I am nearly certain that the hoses are correct and that the valve rebuild is correct but I will check these. Jim, thanks for the papers. I will read through these as well. It could be an adjustment problem.
