Model X rear left axle clunk noise

Hi! Anyone has ever experienced such clunking noise coming from rear axle? This noise appears while accelerating and regenerating at any speed. I’m sure it’s not a piece of stone being stuck in between, ‘cause driving on old stone road no noise whatsoever can be reproduced.

Video is here:
 
It's a failing half shaft and/or bushings/control arms. Are you absolutely certain it's from the rear? I felt like it was coming from the rear too but it ended up being the front. Sometimes it's hard to tell when the car is moving. Either way, Model X's half shafts and CV joints are pretty anemic and need to be replaced every 5,000 miles to remain perfect.

Thank you. I’ve double checked. The noise comes from the rear right (driver side) wheel. Front is fine. We drive only in chill mode and never do acceleration, just silky smooth driving. Bushing/control arm should be fine: a wheel alignment and full break service were performed this year in February. This noise appeared only 2 weeks ago.

Wonder if it could be a loose tire weight or something? The other alternative - when I removed the underbody plastic panel to install my Drawtite hitch, there was a metal piece (and don't ask me what - I forget now) that would "click" like that until I tightened in the 10mm bolt.

I listened to the video and have the exact same sound, coming from the rear wheel on drivers side
