I just changed out the belts on my 72 and noticed that after the change the power steering seemed to be acting up. Now the car is all original with 162k miles. The actual problem could have been there before that but I don't drive the car but once or twice a month on the weekends. When I bought the car it was just chattering when you went all the way to lock but now the steering is jerking and chattering any time you turn it. The pump doesn't appear to be leaking (the only thing that isn't). Is it time for a new pump and reservoir? No flaming now. I'm a rookie mechanic. Thanks for any help.
