Turns out the system is fine. You have to go thru the diff warming drive cycle; don’t turn the truck off, jack up the front and check. Both of mine were fine. Trying to pay closer attention to if I only hear it in the first mile when it’s still cold, or if it’s all the time and there’s something else wrong. Still doesn’t explain pulling in 4wd on dirt.
