I've had a lots of trouble trying to make my 73 maverick a power steering car, i had bought all pieces for the steering system (used parts) and then had them installed. After installing everything we tested the system and when we started the car the steering wheel moved by its own to the left, we thought it was adjustment so we send the control valve on its way for rebuild and calibration, when it came back we did the same test and made sure to bleed the lines and still had the same problem. At this point i thought it was a circulation issue because my pump and control valve felt real hot real fast so i thought it was the pump so we send it to get rebuild and when it came back it still had the same issue (turning on its own, steering felt hard, valve and pump heating). By this point i was annoyed and went on and buyed new control valve and pump and borrowed a cylinder from a friends working maverick, well it didnt work again. I was wondering if anyone had experienced something similar or someone who knows what my issue might be, im so close te resign and just have my car driven with manual steering. I would really appreciate if someone could help.
