After dicking with it for a day and a half in the cold, I was at the peak of my frustration and ready to put the truck in a ditch and walk away. I was hoping whatever was acting up would reveal itself at that point in the parking lot. That's why I was being hard on it.
Edit. Btw mechanics last name was gannon lol :slorg:
I use it on icey roads so it only engages when I need it.
I'm still surprised it was the hub as I checked it less than 1k miles ago and it seemed fine. And to add to it, it sounded like the noise was coming from the driver side.
It usually is always the opposite side of which side it sounds like. I just installed my 3rd set of Hubs in my silverado. Ask me how I know haha.
And just put it in 4HI. Auto uses clutch packs, and they wear outeasily, and turn your fluid a burnt color. 4hi, or 2hi. Only thing I use. I had it in 4lo once. definetly pulled bout out well
