It's the nature of these aging 3s if you ask me I've been having odd clicks and clacks for 20k-30k miles and I'm around 140k. My suggestion is to get under there and do the work yourself. Easier said than done, I know. I was totally intimidated when I first started but it's the only way to stay away from dropping 5k in repairs on a car that's worth around 5k lol. It's a pain and it's difficult but it's rewarding. Only thing for me is find time and a place since I live in Chicago with no parking lot
