My car all of a sudden had no power steering, and after verifying that the pump still seemed to work, I'm assuming that the hose is bad as well. I really don't know though and am still looking. Powersteering makes a really loud noise when I turn the wheel and the car is not keeping the power steering fluid.

Had a leak in the high presure side of the power streering, was leaking and the Dealer said the line had to be changed at $200.00 plus for the part and labor. Took it to a regular shop that I use. He got what he needed at NAPA for $60.00 and I got it fixed for a little over $100.00. I have found that most of the issues can be fixed by regular Auto repair shops.

power steering, the high pressure hose is leaking and has to be replaced - labor cost 485.00 - hose is 36.00 + tax we will be buying a toyota from now on. American made is not what it use to be.
