I have a Toyota Camry 2001 4 cyl 64000 miles. Does this car behaves only if I service it at the dealer? I flushed and replaced the steering fluid at a station specialized on oil service. They show me that the fluid is dirty and needs to be changed after 60000 miles. I asked them if the replacement fluid is the right one for Toyota, they said yes. Two days after the change when steering, I hear that high pitch noise (it seems that noise comes from under the hood not from the steering column) and the steering wheel moves very hard. This happens when steering on both right or left side, not every time (4-6 times in 10 days) and I think when it is cold outside. The fluid it is a the right level. What might be wrong? Thank you.
