My front wheel make whining sound from front. if I push gas, I hear whining sound if I let go of the gas whining sounds goes away. i'm pretty sure it's whining at higher speed as well.

I took it to dealer because I have extended warranty left. they said it's fine. nothings wrong with it. I thought it was bushing, because i see on of my bushing looks bad.

also I need alightment is not right dont know if it's because of whining sound from front, it's leaning towards my right little bit.

 

You sure it's not the front axle? Pull the front axle drain plug and look for metal on the magnet. You may have quite a bit being a Denali AWD. Just my .02...

 

I have rebuilt several front ends in Denali AWD for this complaint. You might check your'e tire presures, sizes and relative wear. Anything that makes the front end spin at a different speed than the rear will load the gears making the noise louder. Gm has a bulletin that states that some gear whine is inherent and there is a new driveshaft with a dampener that will help reduce the noise. PN 15186002. bulletin #03-04-17-005
