What is this noise? Coming from the rear(soundclip)

[BlueOvalStangGT]

Hey this noise has been getting worse and worse lately. I think its coming from the rear but im not sure. Its only when the car is under load, once im coasting it goes away. If you listen closely you can hear this noise that starts at approx 48mph and stops at like 53 mph too. At the end you can hear how its only under load(I was getting on and off the gas ). Im guessing its the 3.73s, maybe they got outta place and they are whining or maybe a bearing? Can I fix it myself?

i have no idea what that sound might be but it sounds really bad. especially towards the end of the vid.

i would find out the prob asap. to prevent some serious damage

This was with the windows up and the back seat out so the camera picked up the sound real good.

I would pull the dif cover and see whats up...

I would check the pattern and see where its at for starters...Did you replace all the bearings in the swap???

Who did the swap and where things properly TQ'd ??? That might be an issue..

Corral has a good gear swap write-up and shows patterns and what noises causes them...http://www.corral.net/tech/drivetrain/gears.html

It's deffinately a whine associated with gears in the rear or trans. I can tell by the way it "disappears" when your off the throttle. Pull the cover and start counting teeth. Then start checking bearings and what have you... my old trans made noises like that before it went kaboom.

any vibration etc........i was gonna say that it may have been a u-joint..but who know......


Honestly i would have to agree with the above and say it is in the gears.....

Should I try to tackle this myself or should I bring it back to the shop that put them in?

I wouldn't open it up if SOMEONE else did the work....that way they cant bang you for messing with it....
I would go back and them to take a test drive with you...let em hear it for themselves....From what you say, I'd say the noise is more the dif than tranny??? I would check that before you bang someone on there workmanship...dont wanna be eating crow...
Where they new gears? How long ago on the install??? Was it quiet than the noise came about with miles??? What brand of gears??

I would think if its whining, that would be more the gear set-up..any clunking along with it while cornering of letting the clutch out? A whine normally isnt a bearing...that would be a squeel to me..

Good luck with it...

They are richmond gears and id say they were put on a lil less then 10k miles ago(not even a year). It started after a lil high speed cruizing to orlando one weekend.

gears

most probably gears, get em checked asap. if you have whine on coast or decel its no prob, but whine under load is a whole nother animal. it could be nothing, you could be knife blading your gears. go to the shop that did it.
