Exclamation Front Diff Grinding Noise?

We got a big snow fall last night so I through the ole 6.4 in 4x4 ( first time I've used it, just bought the truck a month ago) and I noticed it was making a very noticeable grinding or binding noise.

the 4X4 engages beautifully and works great, except for the nasty noise it makes, and I'm very concerned.

I did test the 4x4 when I bought the truck but I only gave it a jolt to make sure it worked, I didn't notice the noise..

Has anyone else experienced this? I hope its not baffed.

p.s. it makes the noise if the truck locking hubs are locked or on auto.

Any updates on this issue? I used 4x4 high a few times in the past couple of weeks in the snow. I get a grinding, metal-on-metal, noise when I let off the the gas and coast. This is most noticeable at speeds in the 30-40mph range. Once I press the gas again, the noise goes away. It does not make this sound in 2wd, so it is not a brake issue.

Any ideas?

Definitely a lash issue. If it's under warranty, it should be covered. If not, take it to a driveline/differential shop. It's a pretty specialized skill to set gears properly and it can be quite time consuming.

Not sure about the others since I'm assuming it's similar to what is occurring in the video.

I'm definitely not getting a noise like that video. Mine is more like the sound of a knife edge on a sharpening wheel...constantly, steady "shhhhhh"... And only in 4wd, only when coasting.

I'm waiting on my main drivetrain guy to come back from back surgery. I don't know jack about back-lash or other differential gear settings. It was suggested that I may have bad carrier bearings, because when I press the skinny pedal the yolk or bearing sort of spins tight and and the noise stops. (?)

I will let you guys know after I get it looked at.

Check the driveline to the front diff, might be warped or just worn.

Had a simmilar issue, took it to Ford and was expecting the worst. new hubs and $1k repair bill. The tech said he pulled the hubs apart and everything was bone dry. He greased it up and put it back together. Truck has been quiet since and that was 2 years ago. Cost me $90.

Mine makes that same noise as in the vid but not as loud. It started as a squeal after mudding one day and hitting a rut kinda hard "at least thats what I'm thinking did it"...I bought my 08 used w/ 100K and that was the first time out mudding kinda hard. Now that the squealing has gone away it's making that same noise. It won't do it on a lift only on the ground. It has gotten a little worse being I've had it at the track and put about 10 runs through it. I was afraid it might have been the transfer case. Guess I'll pop the diff cover off and see if there is any damage and get back to ya'll. Kinda pisses me off
