06 Nissan Altima, bit of rattling behind one wheel, away bar end link boot is all that looks out of place. Is that my answer?
Noticed a light rattling from this corner when I hit certain bumps. Pretty new to taking care of my car, figured I'd at least take a look. Nothing looked out of place or had any play at all, except this torn boot on my (i think) sway bar end link. It sounded very light, I even thought it might be my splashguard, but that's solid too. Could this boot be my answer? Based on this picture, is it an urgent fix?
Would be happy to provide more pictures or hear more things I should try, thank you very much in advance :)
