Is this happening while sitting still in park, or when driving ? More info is needed.

no it mostly does it when accelerating and when at higher speeds and rpms

The LS has a 2 piece driveshaft with a center support bearing midway between the transmission and rear differential, (drive axle).

From your description... it sounds like that bearing is shot.

It's roughly $200-250 for the part... and roughly 2+ hours for the labor at an experienced shop.

The rear half of the exhaust has to be removed... along with the underbody shield. The rear coupler on the driveshaft is a balanced assembly... and the bolt collars have to go back into the same holes they came out of.

Plus....there are shims at the center bearing that need to go back in the same position they were in when the driveshaft is removed.

The driveshaft will have to be separated at the center bearing... and the driveshaft reassembled after the new bearring is pressed on the driveshaft.

Here's a pic of the part, and part number.

And a pic of the other side of the part.

I would not drive it anymore... until you get the bearing replaced... or you may do much worse damage.
