04 Yukon Denali Whine At Very Light Throttle

[Graham_Denali]

I have an 04 Yukon Denali that whines at very light throttle, coast, and light deaccelertion between 40 and 70 MPH. I can pick out the whine at lower speeds, though it is not as noticable. I have 73K miles on it now, all freeway, and recently had all fluids changed at the dealer: Transmission, Differenitals front and rear, and Transfer-case. Still the noise presists and now I think it is getting louder.

 

1)Is this the differential or Transfer case.

 

2)Do you think this represents an early 'wear' condiiton that might precipitate an early T-case failure? (Assuming it is T-case)

 

I have an extended GM Warranty to 90K miles and would like this fixed, as I plan to use this Truck till 150K Miles. I love it, it is the best SUV out there.

 

3)What words can I use to persuade the warranty plan and dealer to fix this?

 

4)What criteria should be used to determine if this warrants warranty coverage, this is excess wear I presume, and represents an owners 'sticky' issue when working with the dealer. We buy these extended warranties to assure longevity.

Thanks for your help

I have the same whine on my 04 Denali, they replaced the Power steering pump and I still notice it. What did you end up finding on yours?
