This happened to me a few times - hit a minor pothole with the rear and it seems like the right rear shock is about to blow - I had a rear passenger yesterday and she even remarked if everything was ok with the right rear corner. I'm not sure if the same happens to left rear or perhaps it does and I just hear the drama coming from the right rear side of car.
I do have the Sports package and running 20"s; 285/30 rear rubber....
Anyone else experience this or should I get the rear shocks checked out?
