01 Tahoe Rear End Whine

[Bedore]

Greetings all,

I noticed while taking an extended trip last weekend occasionally I will hear a whine that may be coming from the rear end. It's mostly when I am coasting, and seems to go away when I step on the throttle. Is this something from the rear end?

I along with many others have a whining noise too but mine is coming from the front end...It goes away when I turn left and stays if not gets louder when I turn right...
Im thinking wheel bearings going bad...
maybe you are having the same problem

Check pinion bearing

Check pinion bearing

wouldnt that be opposite? Whine when on the throttle and dissapears when you let off? or is that ring and pinion im thinking of

whao you get 60mpg? Try a rear diff service. I noticed that on mine too, But i had 2nd row folded forward, and 3rd row Removed. I dont hear it so much with everything in place.

Are any of you AWD? There was a TSB for the AWD system for an internally balanced front driveline if the coasting whine was loud enough. My denali does it but 160K miles on a set of gears, they're probably a little sloppy!

yeah more like 13mpg lol anyways i already flushed it twice with 2 different brands of synthetics still had the same noise
