like the title of the thread says...

at EXACTLY 30 mph, and no other time, there is a very loud squeaking/squealing sound that i think is coming from the front driver's side of my car. the sound occurs in any gear at any rpm, but stops if i put in the clutch. i thought about it being the differential bearings, but i think i would get a more constant noise if that was the problem, right?

car is stock, maintenance is all up to date. runs great.

any input?

 

I have this weird noise coming from my seatbelts. Whenever I move I hear a squeak. Has anybody heard of this before?

 

How is the sounds only occurs when youre at 30mph and at no other time but still can be heard at any gear at any rpm?

 

yeah, my bad.

to clarify:
in 2nd @ 3k, 30 mph: whining noise
in 3rd @ 2k, 30 mph: whining noise
in 4th @ ~1.6k, 30 mph: whining noise
(i don't go 30 in first or fifth)

those are the only times it can be heard.... any gear at any rpm while going 30...
