Quick background, pruchased the truck 1 month ago, 99k miles has auto ESOF with auto hubs. Truck has new ball joints, and swaybar endlinks and bushings. Just yesterday it started making a loud grinding/rubbing coming from the right front wheel when turning left. Now is doing it when I turn left and go over bumps. Thinking it was something hub related, I pulled the hubs off and swapped sides and it still does the same thing. The noise will not happen with the truck jacked up. When I had it up spinning the wheels, look at the video. With both hubs in auto truck is in 2wd watch when I spin the left front, it spins the axle and the drivers side doesn't? Aslo of note the 4x4 engages and works fine with the same noise.

Here is a video of the noise while driving, turn it up its kind of hard to hear! First noise is a 3 sec, then 10 and 12 I am swerving left. Then at 22 I am turning left, and again at 42. Hope this helps thanks.
