My civic is making a clunking (best I can describe it) sound on the front passenger side but only when I hit bumps with that side and not every type of bump. Originally it was hard to reproduce when I wanted to really hear it, I can reproduce it every time by going over a speed bump not on the way up but as it comes over and down it. The car is under warranty and I have been to the dealer twice and both times have been told they can’t get the tech to reproduce the sound and lifted it up and checked everything(which I highly doubt as it took 4 trips with my wife’s odyssey and multiple random parts to replace her front end issue) any ideas on what I can look at myself so I can go in with some evidence and say check this?
