Thanks for the clip, very interesting. Seems it is far easier today to roll it back than in days of old. Which means it is happening more frequently…Thought so too until I watched this report:
It's a 4x4 with the L9H 6.2 motor. Meaning, it has no AFM and no AWD, it's not a Denali. In 2010, all of the Denalis had the new L94 6.2 which were equipped with AFM. These also got the Saginaw 9.5" 14-Bolt axle.
