'18 3.73 PP Diff whine

[SilverUri]

Is this another crashed car gray market import?

What mods have you confirmed have been done to the IRS and diff? Not saying it's not a bearing.

Nostradamus? it's you? dunno if IAAI is gray market import

GT 2020 PP1 10R80

Front crashed and repaired, no engine damage. Only the radiators needed to be replaced.

MODS? CAI JTL, TUNE, catless loud Roush exhaust, lowering springs, BMR toe rod ends
Torsen 3.55 diff. (PP1 included) There is howl sound during driving. Repleaced diff oil, and no change. I need go to good diff shop for diagnostic.

I can hear it while driving, accelerating, decelerating, but after engaging N, the sound suddenly disappears.

You didn't answer the fooking question. Put it on a lift and take a good, hard look at all the IRS/diff mounts. And put it on a Dyno so you can get a decent recording.

Funny xD No IRS/diff confirmed mods. I will let you know after diagnosis what was the reason.
