As the rear tires of the vehicle passes over bumps 30 mph or so; I hear a rattle/ thumping type noise coming under the left rear passenger side of the vehicle. I jacked the rear off the ground; check tire rotation, side to side movement, bolts, nuts and schock security; found nothing. Shocked vehicle back and forth and bounced on the bumper; found nothing.

Can you point me in the correct direction of what can be the issue causing the noise???

The first two places I would look would be the bushings at the sway bar to frame and then the stab link.

Grab the sway bar close to the bushing and agressively push pull.

Same on the stab links. Alos be sure it in nothing on the interior laying inside any compartment and be sure the spare tire has no movement.
