So I've been dealing with this clunk on my '14 6.2 Sierra crew s/b. It is most noticeable when letting of the gas in second gear, but is also noticeable in higher gears to a lesser degree. It will clunk every time I let off the gas in second gear. The driveline will absolutely not clunk in first gear. The first time I took it in to the dealer the service manager rode with me and agreed that the clunk didn't seem normal and suspected the rear axle or driveshaft was the culprit. I was pleased that he appeared willing to dig into the problem and was hopeful for a resolution. Later that day I returned to pick up the truck and was told that they performed the TSB relating to torqueing the shackles and U bolts. I didn't expect that to fix the problem and it certainly didn't. I brought the truck back shortly after and they checked for any TCM updates to no avail and opened a case number with GM. After that they handed me the TSB stating that clunking is normal. Yesterday I went in for an oil change and told them I'm still not satisfied with the low speed clunky driveline of this truck and asked to drive one of their loaners to compare the low speed driving characteristics. The truck I drove had no noticeable clunking at all. This test drive only reinforced my belief that something in not right with mine. Of the 5 late model full size GM 4x4 vehicles I've owned none of them clunked like this 2014. An occasional clunk is to be expected especially in a 4WD and I could live with that, but this thing clunks all the time! This does not seem appropriate for what is otherwise a very nice driving and expensive vehicle. I am totally frustrated with how my dealer and or GM is handling this case. Has anyone had any luck getting this type of issue fixed? Any insight is appreciated.

I recently installed a glass pack with an axle dump on my 2006 Chevy 1500 with the 5.3. When I rev in neutral or park I get a lot of crackles and pops, but when I’m driving I get none. My truck becomes completely silent on deceleration, and i don’t hear any engine noise at all. Would I need a tune to fix this? Anyone else with this problem?
