My 1960 is a daily driver for almost 13 years now, it has over 112k miles on it and i think my power steering is almost broken or is broken. It still works and its not making a shhh sound like it needs more fluid. It is making a winning sound that i can feel in the brakes and it the steering column itself. It happens when i make a right or left turn. Can anyone help? its driving me insane.
First thing to check is that the belt is tight...barring a bad or loose belt, it could be the pump. It's easy to replace...(going on memory here) there's just the bolts for the bracket on the block, and there's the two hoses. Use a line wrench on the high pressure hose if you can so you don't strip the head of it. IIRC it's not that hard to rebuild if you can get a kit, otherwise you'd need to hunt down a junkyard unit. I had mine apart years ago, and I think there were two bolts holding the "guts" in the housing (once you get the pulley off). I had mine apart when I rebuilt my 394, and I cleaned and painted the housing...can't remember if I rebuilt that one or not, but I've done others before.
My first thought is definetly just to check the belt though...jerky steering and noises are almost always just the belt. At 112K, I'd be extremely surprised if it was the steering box...I've driven rigs with well over twice that and never had a problem with a Saginaw steering box. Doesn't mean it can't happen of course, but it would be last on my list
