On Tuesday I had the shock absorbers on the rear axle changed with my car (Toyota Auris TS HSD) (at the pit stop – chain). The driving behaviour became noticeably better – but now I have a loud flap, like from a loose disguise or cover, which beats cheerfully. That was also my first thought, however, I had the trunk full and could only look at home. The disguises are all fixed, there can be nothing. I didn’t make it anymore, because I was on vacation the next day. On the way back I had traffic jams – I didn’t make it anymore. I haven’t put myself under the car yet. Someone has a clue what can clapping?!? I changed the shock absorbers in the back of a car only once, that was over 14 years ago, and there was nothing going on afterwards… The flapping (no polterns!!!) definitely comes from the rear, and is mainly from the passenger side.
