What causes car vibrating when driven on 2007 Mercedes-Benz S550

Car is ahaking(vibrating) just started about a week ago, it has new tires new brakes new rotors and it has had an alignment. Could it be the recall ball joints the car has about 50,000 miles. We are on vacation about 400 miles from home. should we have it checked?

The person answering this question was right. The Mercedes "Flex discs" isolate vibrations on the driveshaft. The problem with them is, they fail between 50 - 100K miles on S550's between 2007 - 2010. You will initially feel a slight vibration when accelerating and ultimately, the shaft will constantly vibrate. There won't be any error messages however, IMMEDIATE action must be taken. By not replacing these pieces your transmission will fail. There are two flex joints and make sure you get the right ones (8 holes) specifically for the S550. They vary in price but you should be able to pick up a pair from eBay for about 190.00 each.
