Technically the rear shocks aren't struts, it's just a shock so it takes no lateral loads.
I'm having a hard time deciphering what noise you're talking about in the video, is it the higher pitch pop/click (heard from 5-9sec and again at 20sec) or the lower pitch thunk/groan sound heard from 9-12sec?
The noise could be from the shock assembly itself, or any of the suspension components, or it could be the rear deck pop/noise many members had a while back.
