I have A 2023 Lariat with a 3.5 and since about the first week owning it (bought with 3800 miles), there has been a grinding/vibration thru the gas pedal (more grinding now). It started infrequently but now it’s all the time and obvious. It’s more so when you are giving it gas and doesn’t change between 2H/4H/neutral. I’ve been to the dealer 5x and they barely do anything. I’ve posted on numerous platforms and many have the same issue but I haven’t seen any resolution. Does anyone here have any insight to what this could be? Bearings, IWE?

 

Are you changing the text color? This is what your post looks like on mobile for me. Lol.

Edit: I can see your text if I enable Samsung Browsers dark mode but it's hidden when looking at it with just the forums dark mode.

 

I had copied/pasted my text from a different app. I guess when it pasted, it was black font. I just changed it to automatic.

 

The entire front end drive train spinning needlessly. All that rotating metal and chattering kills the front diff , and possibly other parts . It's a stupid thing .

Had a 2012 (much earlier I know). Slow build up of intermittent grinding…hard to diagnose but by switching in/out of 4x4 and 2X we felt strongly it was the IWE. Bit the bullet and replaced…curing the noise

 

That would be a fine suggestion to the OP if his truck had IWE but it does not.
