My 2016 200 Limited has been making a loud noise seemingly from the rear whenever I hit a larger bump. I'm thinking maybe the car hitting the bump stop like the shock is bad. I haven't noticed any wetness on either shock. Car doesn't overly bounce when I push up and down on the rear. Before I go ahead and replace the rear shocks is there anything else i should be looking at? Any one experience that kind of noise? Car has about 78K miles.
