The power steering of my 90 N/A builds resistance when I turn and makes a squeeking noise. The power steering fluid seems to be leaking, also. I took it to the local dealer and was told that all three hoses, the pump, and the steering rack need to be replaced. That's a total of $3000 including labor. I asked whether the problem could be localized but they said that everything needs to be replaced. Can I trust them or should I get a second opinion? Any advice or suggestion is greatly appreciated.
