My 2010 LR4 with 80k miles makes a nasty scraping noise when turning hard RIGHT and backing up. Doesn't happen while turning left or moving forward. See video to hear the sound ... Both front lower control arms were replaced recently. I took the vehicle to an independent LR specialist earlier. He applied grease at some specific points where the steering locks at full turn. That seemed to have sorted the issue for 3-4 weeks, but now the noise is back. Any clues where the noise is coming from?
