Suspension Problem. Rear Bounces and Skips over Bumps.

Thank you for your call following the diagnostics and inspection on your vehicle. As discussed, we have found additional play and movement within Both rear Longitudinal Suspension arms. These vehicles are known for the rubber bushes on the end of the suspension’s arms dropping lower than there housing, causing the arms to have more movement and cause the issues which you are experiencing.

That’s from a ds dealer here in the UK.
Mine is going in next month.
