Bringing this one back. Been dealing with a nice pop noise from under the cab whenever I leave my driveway or make a turn. I've got the new style rear mounts, and have replaced the other 4 body mounts with a mix of dorman and new GM (ebay deals). Still making the noise... Tried the TSB fix first which helped solve it for a few months but it has since came back.. I'm going insane over this stupid noise, even 5" exhaust can't hide it!
