No mine does not do this, its more of just normal straight driving and going over stuff, some times it does it and other times not. Tried replicating for a dealer, but at the time car would not do it :(.

I don't know your technical ability but if you do not have access to a lift to examine things, then maybe you might want to invest in one of these. They have a price range depending on how much you want to spend.

I had a occasional RR clunk and found RR knuckle had a bad spherical upper joint took a cell video and I bought a used knuckle hub and parking brake/splash shield too about an hour to swap it. Justice Pete advised me to get it up on a lift and put a wrench on all bolts and when I did the toe arm it was easy to see
