Hey guys. i own a 2004 g35 coupe AT. i bought it with around 60K miles, and now up to just below 96K. Yeah, gettin' up there, i know. Anyway, about a year after purchasing the car (early 2007), i started to notice a screeching sound (metal abrasion/rubbing sound) at around 2,900 - 3,100 rpm under hard acceleration, then proceeds to disappear until another hard acceleration. Any thoughts from our tech guys?

p.s. i am going to try to get an audio/video sample for you soon.

ALSO: what is this ''woosh'' sound, (not consistent intervals in between noises/vibarations), around 55-65mph?? Wheel Bearings worn?

Thanks guys, I do appreciate all your ideas.
