whirring sound?

[DHiser27]

I just bought a 99 Firebird a couple days ago, and i just noticed a soft whirring sound that increases as i go faster. every car Ive driven before this one has never made this sound. Im hoping its just an F-body thing. it sounds like its comming from under the car. any help?

Re: whirring sound?

first things that come to mind are, tranny and rear end.

is it coming from the front, rear or both? When you say increases as you drive or when you push on the throttle... if it does it when you are in neutral then it probably isn't the drivetrain. Give us some more info.

Re: whirring sound?

its as my speed increases. it sounds like its comming from right under me...so i hope its the tranny, cause im gonna be swapping the auto for a manual pretty soon here.

Re: whirring sound?

probably just from the driveshaft then.

so its just normal noise from the car? thank god...ive driven a Bonneville forever so im used to cars that GM took the time on making quiet. they must not have figured people that drive these cars care much about noise, which i dont, i just was hoping it wasnt a problem. Thanks guys.

I don't know if its normal but thats probably where the sounds is coming from. There isn't much else to make a sound under your seat except the driveshaft. Get under there and take a peek.

well... its hard to tell. I'm not sure what a whirring sound is. I mean it could mean something different to me. Get in the car... rev it and listen for the sound. If you hear nothing then drive it or have someone walk next to the car and listen for an exact or close area.

Get under the car, find that spot, and look for anything out of the ordinary. I'd move things around and see if anything is lose. You can see if anything makes any noises when you are investigating. I just don't know what would make a whirring noise. I mean the driveshaft may not be true.

Re: whirring sound?

well, found the problem i hope. the differential is leaking fluid, so i figure the gears may just be makin some noise because they arent properly lubricated. im gonna get readin up on how to fix said problem, if anyone can help out that'd be great. is a special fluid and gasket needed? im sure there is, i dont even know why i asked that.

Re: whirring sound?

My buddy's dad does all rear end work and pretty much amazing at it. I get the same sound as you (like a howling sound). He said it was the rear end and that it wont hurt anything. It just gets annoying.

Re: whirring sound?

are you sure? i think i need to go to a dealership and test drive one of their V6 F-bodies just to see if it gets the same noise. I checked the fluid in the differential and it definately wasnt low, just black as hell, so im gonna change it. its hard to explain the noise. its not loud at all. you can only hear it when the radio is off and the windows are up. i sure hope its nothing, just the sound of a car with a differential. this is my first rear wheel drive car, so im just hoping its not the driveshaft U-joints or anything like that.
