Oh man, Steering problem

I worked at a garage and we did all the repairs for Hilsborough Co. Sherriff Dept. They were all Coronets. Like 64SignetConv explained is exactly the procedure we use when we had to reseal a P/S box. I don't know why you had so much trouble with yours, maybe the different years of the valve and your steering box? But i never had a problem centering the valve. We did it with the front wheels off the ground and we would rev the engine up before we let it down to make sure the wheels stayed center.
