05 Rear Diff Whine vs. 02-04

[LiKuiD]

Hi All,

Wondering if anyone knows if the rear end whine was solved in the 05's vs. the 02-04's. My 04 has the usual terrible whine at 60mph and it's been tolerable for 40k miles but it's starting to drive me up a wall.

If the 05's had it fixed, was thinking of doing a used axle swap vs. replacing existing bearings/gears. Any thoughts?

My parents ‘03 had this. Multiple trips to the dealer up to and including them putting in a completely new rear end (not just parts) and it would always come back.
I’ve always wondered if it wasn’t due to a driveline being out of balance ever so slightly.
