have an 02 is300 auto with 160k miles. recently started noticing a whining noise. it sounds like it's coming from a fan somewhere closer to the driver side. but it only happens after being driven for about 20 mins and only after i take hard turns. the sound is never there at start up. once the noise start, if i park the car and turn the steering wheel, the noise gets louder as if something is rubbing. any ideas what it might be? thanks.
