I am nearing trade in time on my 11. It has a noisy rear diff and the internet is riddled with stories about the rear differential/pinion issues.... have they figured it out on the 13's? may go back to Silverado if they haven't.... thanks.

There is a recall for the pinion nut loosening. Supposedly the issue was fixed from the early '12s on up as they are not included in the recall. My truck was built in 01/12 and is not included.
