So a few nights ago I noticed as I was turning into my neighborhood, going about 5 mph, I noticed weird humming noise coming from underneath do the truck.
Not sure if it was vibration going on on or what it was but it was doing it today too. Almost like a groaning grinding noise but I can't tell if it's coming from the tires, transmission, engine, I have no clue.
Has anyone else had this?
Of course it doesn't happen every time, just started doing this at almost 17,000 miles and it's pretty subtle so I have a feeling bringing it in wont do any good and they might claim that they can't reproduce it.
Things just keep on getting better and better with these trucks

When did you rotate the tires last?

Can you describe yours? Is it all the time? Have you taken it to the dealer?

Last oil change, about 7k ago, I'll be doing it again within a couple weeks. It doesn't seem like it's the tires though

I did take it in bit that day it wasn't doing it. I notice it more when it's warmer. When it does happen it sounds like its only happening on 35% of a revolution

Bingo. I was scrolling, waiting for someone to suggest this.
Integrated Wheel End vacuum issues will cause EXACTLY what you are describing.
