I've owned a LR RWD for about 2.5 years now (since May 2018). I'm just shy of 30,000 miles and have had it lowered on TSportline springs since August 2018. The 1" drop put the stance right where I thought it should have been from the factory. Anyway, about 2 months ago I started hearing some noise (slight knocking/glonking?) in the rear, mainly at slower speeds going over uneven road surfaces, speed bumps, pulling into the driveway, etc. I brought it in to where I got it lowered and it was diagnosed that my rear driver's side shock was leaking and not functioning properly. I then took it in to Tesla and they agreed, actually replacing both rear shocks under warranty. Problem solved right? Wrong. The noise was still there. I took both wheels/tires off to look for any loose bolts, or to see if the rubber isolators were seated incorrectly. From what my novice eyes could see everything looked good. I attached some photos (not sure they'll help at all) but the main thing I was hoping you all could check out was the 30-second video I took. It's just me jacking the car up, and lowering it back down slowly, but you can clearly hear the sounds at the end of the video with three distinct "glonks" (haha) that get a bit louder until the car has settled back on the ground. Tesla, after having my car for nine days, didn't actually diagnose the issue. They simply stated that they believed it was the lowering springs and that I should reinstall the stock springs. Number one, I'm not convinced it's the springs. Number two, I simply can't take the stock height, with that huge fender gap. Safety is obviously the biggest concern here though. I will be taking it back to the shop where I got it lowered this week but would really love any ideas on what exactly this could be. Thank you so much in advance for any help. It is greatly appreciated.
