Does anybody know what could cause a whining noise up deceleration? As soon as I take my foot off the gas there's a whining noise that lasts until I slow down to about 15mph. I don't think its the tranny cause it makes the sound in neutral too. I have a 2000 jeep cherokee sport btw.

Any help is appreciated.

is the weather cold? could be a number of things where is the sound coming from? engine bay .. below the jeep.. by the tires ? wheres it comming from does it only whine when your decelerating or is it when its idleing too?

It only whines deceleration (Alothough it might whine while driving but its not too noticeable). I live in Orlando, Florida so I doubt it's the weather. Sounds like its coming from under the body maybe mid to rear-end.

5 speed?
its possibly the throw out bearing.

Check the rear end, especially the Pinion Bearing for slop. I'm pretty sure its common for the pinion bearing to whine under decel if its shot.
