When I accelerate from a stop, (easy or more aggressively) the rear end feels as if I am running over some small speed bumps.. .like you might encounter when coming to an intersection on a country road. it feels like perhaps 6-8 bumps.. or chatters. It sounds as if it's coming from the right rear wheel... but I realize how sound direction can be deceiving but it's definitely coming from the rear end.

There's not a lot of miles on the car and they haven't been hard miles. At first I thought it was the road but now I'm convinced it's the car. Thinking perhaps the suspension but hoping someone here has some familiarity with this symptom and can help me diagnose it more accurately.
