01 Denali whirling noise coming from front differential

I have a whirling or spinning noise coming from front differential at speeds above 30 mph. The noise stops when I release the accelerator, anyone have this issue? From what I read maybe the bearings, any info please help

Sounds like you have a noisy pinion bearing. You should replace pinion and carrier bearings at the same time. Its aslo possible the ring and pinion gears are noisy. The only way to tell for sure is to disassemble and inspect it all.

Ring and pinion have to be replaced, so its in the shop now,
Thanks
