This is what my friend might need for his 2011 Civic that recently developed random rattling after the brake pad replacement along with the fog lights and muffler. We'll take a look this weekend. ThanksGo and buy yourself a pack of these.
Then jack the car up and get underneath and see how many of those are missing from the undertrays and the inner wheel well covers. Then check the exhaust heat shields too. Just had to add 4 large washers on heat shields that had rusted through their fixings just this week. Also worth checking the exhaust mounts arent broken too.
It could also be drop links, broken springs, worn arb's, or rotten heat shields behind the brake discs.
