Mercedes S S500 2009 Automatic Gasoline mileage: 197 KM Peace be upon you. I have a Mercedes Panorama S500 with a vibration at around 120 speed. When I'm accelerating, there's a slight vibration, but when I take my foot off the gas at speeds of 110 and above, a strong vibration occurs in the body. I changed the engine and transmission mounts and did a wheel balancing, but the vibration remains. I heard from someone that the problem might be with the driveshaft. Has anyone experienced this problem, or do you know of a workshop in Riyadh or a specialized machine shop for Mercedes driveshafts.
