Mine has been doing the same thing for the past 4-5 mo's but mostly on drivers side and at low speeds in parking lots/driveways etc. replaced my sway bar end links, thrust arm rods and about to do sway bar bushings this weekend. However, mine isn't as loud/pronounced as your vid.

I will try spraying some lube on rest of the bushings and I have no visible damage to my cv boot. I'm also starting to get a crunching sound when chocking my wheel to the left all the way then turning it back right a bit...sounds like something in the steering rack or lower assembly IDK...still looking...about to just get my indie to look at it, just getting annoying I don't have the time anymore.

I have 08 4.8 w/72K now.
