2015 Tahoe/Grinding/rough noise from front of vehicle

[Fless]

Unless you need AUTO for changing road conditions, I would recommend running in 2HI to save wear and tear on the front drivetrain. Try 2HI anyway as a test to see if that changes your grinding noise.

Thanks, I wasn't aware of this. I didn't think it would turn on 4wd if I was driving on pavement. First car with auto 4wd.

Generally, when we’ve had vehicles with Auto4WD, we would only put it into Auto4WD if there was a chance of running into questionable road conditions, typically in the winter. Otherwise, as @Fless says, just leave it in 2WD.

Gotcha. Wish I would have know that, but who's to say the person before me wasn't driving like that either.

Either way I've been driving it around trying to diagnose and I can say even in 2wd I still hear the noise.

It's seemed milder as I've not been driving the car much for 2 days as I thought something may be broken.

It sounds like either metal rubbing/or like a creaking metal part. It's very hard to tell.

I'd say it sounds like something rotating that's metal that's not happy.

Record a video and upload to YouTube. Then attach the link if you think the sound will come through

I can try but it's very subtle. I'll give it a shot though.

Have not checked diff fluid, have not changed it since I have owned it. (Only a couple months)

It's 4wd, it seems to engage and disengage fine with no noise. Have not put it into 4-HI a.d driven off road as I have not needed too.

It has ways been on Auto since I have owned it.

It would be pretty impossible for me.to jack the car off all 4 to be honest.

1 jack, 2 sets of harbor freight jack stands and you are set my friend. Jack up front first, set on stands. Remove jack and go to rear - repeat. Viola!

It's very subtle in the video, and the road noise doesn't help. But you can hear a subtle banging noise.

Possible a bad ball joint or tie rod end maybe?

I am seriously lost.

Jacked up all 4 off the ground, spun everything I could. I can't hear anything.

Greased ever joint I could.

Feel like I have checked everything.

The noise seems lessened and I don't really feel vibrations right now, but that could also be because the cat has been sitting, but I really am not sure.
