Snap noise when taking off

when i get on the gas to go i have this snap noise it sounds like a stick braking in half i had the u-joints changed at the dealer but the sound is still there could it be inside the transmission? 47k on the trailblazer 06

The problem might be with the slip yoke where the driveshaft connects to the transmission. There have been complaints of a popping/snapping noise on these vehicles when accelerating from a stop. The fix is, remove the driveshaft from the transmission, and lube up slip yoke splines with moly grease.

WELL 3K LATER AND STILL THERE GM TECH SAID ITS OK ANY OTHER INFO WOULD BE HELPFULL I ASKED THE TECH ABOUT MOLY LUBING THE YOKE NEXT TIME AROUND

DID YOU THINK IT WOULD CURE ITSELF?
