I have a 2020 Silverado RST z71 and am having a different noise pop up. It happens after I've been driving for a little while, 15 minutes or so, and it sounds like a higher pitched metal on metal grinding noise. No noise at all when I start driving, but it seems like once heat builds up, it starts to grind. I don't think it's a bearing, I've heard that noise before and it's not really the same. It doesn't vibrate the steering wheel or brake/gas pedals, I'm pretty sure it's on the front end and not the rear wheels, and it definitely 'grinds' every time the wheels make a rotation, and it seems to go away when I make turns. I don't have 10k miles on the truck yet, got it in July. Had the tires rotated/oil changed in early March.
