And did you have the recall done on the power steering hoses? There is a
recall for 2003 to have the power steering hose rerouted. I had the same
symptoms but waited forever to get it done. There was also a TSB they
performed also, I believe it had to do with a new power steering cooler.
Those two things solved my problem, but that was a month before my warranty
ran out. The recall would be free for you still, but you would probably have
to pay for the TSB for the Cooler, and I believe, it was relocated, and
installed lengthened hose.
