I'm getting a noise from the rear end when I turn in to (or out of) parking lots which have some elevation. 5 miles per hour...imagine making a pretty sharp (but still slow) turn in to a ramped entrance to a parking lot. The noise doesn't seem to be there when going straight over speed bumps or potholes...more just the product of lateral load transitioning back and forth at slow speed. Any thoughts based on the video below? Noise can be heard a few times during the video, but perhaps clearest at the end. The noise isn't as loud as it seems in the video, but still audible to the driver.

115k miles. Fully rebuilt suspension front/rear. At the rear specifically...shocks, shock mounts, reinforcement plates, and RTABs have all been done in the past few thousand miles. Diff and subframe mounts have been inspected by multiple shops and are said to be fine.
