Whine in 4x4?

[WhiteRaptor]

When I shift to 4x4 high, there is a audible whining sound that almost sounds like a vacuum leak or other issue. I went to my dealer and spoke with the Head Mechanic who told me that "this is a characteristic of the Raptor - I know of 3 others that are doing this"

Comments?

Mine doesnt audibly whine when its enabled.

It does grind and Bang when i first turn it on though, hopefully that'll be fixed today.

Take the significant other out when you 4x4?!?!

On a more serious note, I notice a slight gear whine in 4x4 but everything operates normally. If there is one thing the Raptor is not, that would be quiet. Every damn thing on this truck can make noise, but it's no biggie.

Engine - Check
Suspension - Check
Air Conditioner - Check
4x4 - Check

I've got a whine in 4x4, it has never affected anything though. Stereo, Up.

I've noticed it in mine!

Mine has always had noise, no different at 30k miles now.
The whine in 4LO at higher speeds concerned me, but the tech's couldn't find anything wrong.

Thanks, I've definitely heard worse noises! Truck is still new so was wondering about it, sounds like all is good to go.
