Alright guys I purchased a new 2017 chevy Silverado LTZ z71 with the 8spd trans and 5.3L motor, right now I have about 1500 miles on it Whenever I come to a stop I hear a clunk sound coming from the driveline. Possibly slip yoke issue or transmission 3-2-1 gear clunk ?Took it in to the dealer twice already. The first time they sited a TSB stating it's normal . Second time I took it and took the mechanic for a drive to duplicate the issue. Mechanic heard it said they'll look into it. Get the vehicle back a few days later , dealer said they torqued all the rear suspension/axle bolts back down and it solved the issue. I picked the vehicle up and as I was driving home the issue is still there. Clunk can be heard at 35 seconds and 56seconds In the video that I posted. Any suggestions anyone ?
