[MudLovingFJ]

the whine /
Whistle is there even in neutral at speed.

You know, I haven’t tried that on my truck. Will check and report back

Sound anything like this?

Or how about this?

^^^No not like that. No noise stationary.
I went to Dealer this morning. Shop manager rode with me. He heard it to. We did various tests, neutral, put in 4H/4A at various speeds. Sounds still there. It’s loudest and most noticeable around 35-45 mph where the pitch is loud/low enough it’s pretty apparent. The faster you go the higher pitch it gets and gets less noticeable.
He said to bring in and leave it’s not something he’s dealt with on these Raptors yet. Then complained they ever got rid of the V8’s. Ha!! Something we all can agree on. Nice guy, old school.

Sounds like a bad ring and pinion setup in the rear axle. At the loudest MPH, does sound change at all when going from on the gas to off the gas?

no. No change in sound. Gas off, neutral, nothing. It’s all wheels turning on the ground related. Only thing we can’t check is if it’s a bad ground wire through the speakers.
What we can’t know now is if you can hear it from the outside. Shop guy said they can take the wheels off the ground and try to pin point the noise.

Your description above is exact to mine .

It certainly could be rear axle, but I am leaning to transfer case or tail shaft side of the transmission. It will likely be a couple of weeks before mine makes it to the dealer .

I am having exact same noise! Picked up the 2020 Nov 18, 2 miles on it and the whining/whistling noise that fluctuates in tone as you go faster.
It does still make noise when put in neutral and rolling at speed! This is my 4th Raptor since 2017 and never heard this, yes you will hear turbo, but this is different! Still made noise when rolling downhill in neutral as well.

Still haven’t had time to take mine in. Hopefully this week or next.

Anyone else have any updates?

No updates here. Everything still the same with mine.

Not sure who "we" is, but no, "we all" do not all agree with that. Good luck...
