New buzzing noise in front driveline

[Uncle_Booty]

My new ‘23 302A suddenly started making a buzzing noise in the front driveline. Was driving along easily at 45 MPH and it came on sudden. Seems to intensify when turning to the left in a curve.

Feels/sounds like the transfer case or CV axle, but not certain. The pitch changes with vehicle speed, not engine speed.

2,200 miles on the truck.

Anyone else experienced this?

Is it 4WD?
If you switch to 4WD, does buzzing stop?

If so, sounds like one of the IWEs is trying to engage. Partially.

Yes, it is 4x4. I haven’t engaged 4H in 3-4 weeks.

That thread describes what I’m experiencing perfectly! It was below freezing when I left out this morning but it has done it intermittently all day.

What is an IWF, specifically? Wheel end?

Hopefully you have better luck than I did. My dealer could not hear the noise so couldn't isolate anything. Ford replied to my post on this site, but did not offer any help to getting my problem resolved. I just wait until it becomes a big enough issue to where it is more noticeable. Next time in, I might push the dealer to put some chassis ears on to see if that helps isolate the noise.

Thanks for the input. My truck has been perfect until this morning. Maybe I’ll get some help with it soon..
