I recored a video and if you just skip ahead to 3:20 through 3:30 or maybe more you can hear a little ooooooooooo high pitched noise. Its coming from the rear of the Jeep. Im not sure where its coming from tho, maybe a wheel bearing ? Or is this differential noise.. The Jeep is a 98 5.9 Grand cherokee with 118k on it. It really only does this around 55-65mph. It does it on deceleration and acceleration, and it gets faster sounding as the car goes faster. It more noticable to the ear when the Jeep is coasting to maintain say 55mph.

Also apon decelerating to a stop around 10mph to 0mph i hear a noise that i cant really describe it sounds like maybe decelerating puuuuuuu noise then stops when the car stops. Then as i accelerate slowely from say 0-10mph it will make the same puuuuu noise cept it will be a accelerating noise and then it goes away completetlyas i go above 10mph.

It's hard to tell from that video. If it was on a hoist you could isolate the noise with a stethoscope.
My '97 w/the D44a needed new ring & pinion gears, pinion and carrier bearings, as well as both wheel bearings after I bought it.

Did you not skip to 3:20 and listen to it then ? You can hear that noise really good right there

I watched/listened to the complete video, but I'm on a lap top and the sound isn't very good.
