Driveline Shutter When De-Accelerating

[TURTLE]

Im going to replace the rear u joint and the carrier bearing tomorrow just to rule those out since Im finally home and have a shop.

Rear u joint fixed it. Also where the t-case and drive shaft link and there are two round discs that are bolted together with 4 bolts, was loose. The bolts were backing out so I tightened those up too. Smooth as silk now.
