I just did a power steering fluid change following this DIY link DIY: 2008 Corolla Power Steering Fluid Exchange (GEN9)
step by step and everything seemed to go fine until the very end. I am not sure if it has anything to do with the power steering fluid or not though.
When I fully turn my steering wheel to the left or to the right (to the point where it can't turn anymore) I can hear a slight hissing sound like a moving part (i.e belt) is rubbing against a stationary part. If I force it to the left or right a little more it will become a little louder. The noise will continue until I start to return the wheel to the opposite side.
Does this have anything to do with my power steering DIY? I am 99% sure that all of the air bubbles were out of the line.
My girlfriend has a Mazda 3 2005 so for fun I went out and turned on her car and the cranked the wheel to the left and the right. She had the exact same sound as in my 2006 Corolla! A slight hissing when you hit the end of the turning and it gets louder if you continue to try and turn it.
So I feel a little better knowing this but at the same time what in the world is this noise?!
2006 Corolla - 80'000km
2005 Mazda 3 - 159'000km
Does this have to do with the power steering pump? I sure hope they are not going bad because I think that is beyond my skills here. Also I would be surprised if the Corollas pump is starting to go at 80'000km. Anyways let me know what you think.
